In the garden centre sense it means “not a manufactured soluble salt”, which is why mined minerals such as rock phosphate and sulphate of potash still count. It is not the same as a whole-product organic certification logo on every bag: look for named inputs and a published rate. This collection is the browse answer for the full range; the sensible default bag inside it is \u003ca href=\"\/products\/organic-all-purpose-fertiliser-4-4-4\"\u003eAll Purpose 4-4-4\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eWhat are five examples of organic fertiliser?\u003c\/h3\u003e\n\u003cp\u003eUseful examples, not a spammy top-ten: garden compost and well-rotted manure (soil builders); seaweed meal (traces and alginates); milled plant meals such as alfalfa or rapeseed (slow nitrogen); animal meals where listed, such as bone meal (phosphorus and calcium — not vegan); and mined minerals such as rock phosphate, polyhalite, gypsum and sulphate of potash. Bagged multi-input blends combine several of those so one application covers N, P, K plus calcium, magnesium, sulphur and traces. Sort by job — soil building, general feed, or a single-nutrient correction — then browse this range rather than chasing a numbered list.\u003c\/p\u003e\n\u003ch3\u003eWhat does organic fertiliser do?\u003c\/h3\u003e\n\u003cp\u003eIt supplies the major nutrients plants take up as ions, and it feeds the soil life that unlocks them. You get steadier growth and less scorch risk than a harsh soluble feed, plus secondary nutrients many thin NPK bags skip. Organic matter left behind improves structure and water holding over seasons, not overnight. It will not “fix” dead soil in a weekend, it stalls in cold ground, and it will not correct a problem that is waterlogging, drought or root damage. For mixed plots the default bag is All Purpose 4-4-4; crop blends and singles sit beside it in this collection when the job is clearer.\u003c\/p\u003e\n\u003ch3\u003eIs organic fertiliser really better — and what are the downsides?\u003c\/h3\u003e\n\u003cp\u003eAt the root, plants take up the same nutrient ions either way. The real advantage is to the soil: steadier release, less salt spike, organic matter that builds crumb structure over seasons. Trade-offs, stated plainly: slower to act (often 2–6 weeks for granules), a lower and more variable analysis so you apply more by weight, more bulk to store, and almost nothing happens below about 4°C. “Really better” depends on the job — synthetic wins a same-week rescue; organic is the better long-term default for most British gardens.

Compost builds soil; a balanced 4-4-4 feeds generally; a potassium-led blend suits fruiting crops; singles fix deficiencies. Be wary of anything sold as best for everything with no full ingredient list.

That is how to choose — not a celebrity ranking.\u003c\/p\u003e\n\u003ch3\u003eHow do you use organic fertiliser, and how long does it take?\u003c\/h3\u003e\n\u003cp\u003eWork granules into moist soil or compost before planting, or top-dress around growing plants and water in; keep them off leaves and stems; always use the rate on the pack in front of you. On beds, most granular blends sit around every 4–6 weeks in the growing season; pots run out faster (often every 2–4 weeks) because there is less soil and more watering. Granular meals usually start within 2–6 weeks in warm, moist soil and can feed for 6–8 weeks; liquids act in days but fade fast; cold soil stalls everything. Timing detail: \u003ca href=\"\/pages\/frequently-asked-questions\"\u003ehow often to apply\u003c\/a\u003e. A 1.5 kg crop-blend bag is roughly a season for a small greenhouse or raised bed — check each product page.\u003c\/p\u003e\n\u003ch3\u003eCan you put too much organic fertiliser on plants?\u003c\/h3\u003e\n\u003cp\u003eYes. Scorch is uncommon at normal garden rates because release is gradual, but too much nitrogen still pushes soft, floppy growth that flowers poorly and attracts aphids. Phosphorus accumulates and is slow to leave soil; surplus potassium can interfere with magnesium and calcium uptake. Modest analyses such as 4-4-4 are harder to overdo than a concentrated extract, which is not a licence to heap it on. Stick to the published rate, water in, and do not reapply after ten days because “nothing happened” — nothing was going to yet.\u003c\/p\u003e\n\u003ch3\u003eWhat are the two types of organic fertiliser?\u003c\/h3\u003e\n\u003cp\u003eGarden answers usually split two practical families rather than a tidy textbook pair. First: plant and animal meals and composted matter — proteins and fibres that soil organisms mineralise over weeks (the usual “slow-release organic” bag). Second: mined minerals permitted in organic growing — rock phosphate, sulphate of potash, polyhalite, gypsum — which are not carbon-based but are not synthetic salts either. Coated synthetic pellets are a different tool again, even when the shelf says “slow release”. Meal-based slow release is covered in more depth on our \u003ca href=\"\/blogs\/the-dr-forest-blog\/organic-slow-release-fertiliser\"\u003eorganic slow-release fertiliser\u003c\/a\u003e notes.\u003c\/p\u003e\n\u003ch3\u003eWhat is another name for organic fertiliser?\u003c\/h3\u003e\n\u003cp\u003e“Natural fertiliser” is the usual synonym in garden centres, and people also say organic plant food or organic feed. Natural is a loose word: it usually means the material is milled, dried, composted or steeped rather than made as a soluble salt — not that it is automatically gentle or certified. Wood ash is natural and will raise pH if you use enough of it. In chemistry, “organic” means carbon-based, which is why some mined minerals sit awkwardly in the word but still belong in organic growing. Browse this collection for named bagged options; compost remains the free bulk answer underneath.\u003c\/p\u003e\n\u003ch3\u003eWhat is the best homemade organic fertiliser?\u003c\/h3\u003e\n\u003cp\u003eComfrey liquid is the best-known homemade feed for fruit and flowers (potassium-led); nettle liquid suits leafy growth (nitrogen-led); compost is the best homemade soil feed. Seaweed meal or alfalfa pellets can be steeped as a quicker drench. Coffee grounds: their nitrogen is bound in material that takes months to break down, so as a direct fertiliser they do little — fine on the compost heap. DIY is cheap and variable; it will not match a labelled analysis for a hungry crop in a pot. Soft option when you want a measured bag: All Purpose 4-4-4 in this range.\u003c\/p\u003e\n\u003ch3\u003eWhat is the cheapest organic fertiliser?\u003c\/h3\u003e\n\u003cp\u003eHome compost and well-rotted manure win on cost per square metre because they use waste you already have and improve structure as well as feeding lightly. Bagged feeds cost more per unit of nutrient than a supermarket soluble, and organic analyses are lower, so you apply more by weight — that is the honest trade. Within a bagged range, buy the analysis and ingredient list you need rather than the cheapest sticker: a thin NPK-only bag can waste a season. Start with compost; add a default bag such as All Purpose 4-4-4 when the crop asks for more.\u003c\/p\u003e\n\u003ch3\u003eWhat do organic farmers use for fertiliser?\u003c\/h3\u003e\n\u003cp\u003eAt farm scale in the UK, fertility still rests on rotations, green manures, livestock manures and composted organic matter, topped up with materials on the organic standards’ permitted list — things like rock phosphate, sulphate of potash, and certain plant or animal by-products where allowed. It is not one miracle bag. Home gardens borrow the same logic at smaller scale: build soil with organic matter, then use named meals and minerals (or a finished blend) for the nutrients compost cannot concentrate. Browse those bagged options here; farm certification rules are stricter than a garden-centre label, so do not assume every garden blend is farm-licence certified.\u003c\/p\u003e\n\u003ch3\u003eWhich fertilizer is called the king of fertilizer?\u003c\/h3\u003e\n\u003cp\u003eIn agronomy folklore, urea is often nicknamed the “king of fertilizers” because it is a very concentrated nitrogen source (around 46% N). That is a synthetic nitrogen story, not a badge the British garden trade hangs on one organic bag. In the garden, nitrogen, phosphorus and potassium each “rule” different jobs — leaf and stem, roots and flower set, fruiting and hardiness — so the honest answer is to match the nutrient to the plant stage, not chase a royal nickname. For a balanced organic default, use All Purpose 4-4-4; for a single nutrient, browse the nitrogen, phosphorus or potash options in this range.\u003c\/p\u003e\n\n\u003ch3\u003eBlend or single ingredient: which should I buy?\u003c\/h3\u003e\n\u003cp\u003eA blend if you want one bag to cover a crop for the season. Single ingredients if you have a specific deficiency to fix, or you are building your own programme and want to control each element. If you are unsure, start with a blend.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use these in pots and grow bags?\u003c\/h3\u003e\n\u003cp\u003eYes, all of it. Pots, grow bags, raised beds, allotments and open ground.\u003c\/p\u003e\n\n\u003ch3\u003eHow is this different from a supermarket organic feed?\u003c\/h3\u003e\n\u003cp\u003eTwo things. The blends are multi-input, so a single bag carries N, P and K plus calcium, magnesium, sulphur and a full trace element set, rather than NPK alone. And every ingredient is named on the label. For a worked comparison against the feeds most people already own, see \u003ca href=\"\/blogs\/the-dr-forest-blog\/tomorite-vs-dr-forest-tomato-feed-compared\"\u003efive UK tomato feeds compared\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eAre they safe around children, pets and bees?\u003c\/h3\u003e\n\u003cp\u003eThese feeds are built from named plant and mineral inputs (and animal meals such as bone meal where listed on the label — those blends are not vegan), not from synthetic soluble-salt cocktails. Store any fertiliser sealed and out of pets' reach, and keep it off play surfaces. Blends that contain bone meal attract dogs: they will dig for it and can eat enough to upset their stomach or, in a bad case, cause a blockage. Work those blends into the soil rather than leaving them on the surface, keep dogs off freshly fed beds, and if a dog eats a quantity call your vet. Wash hands after handling. Avoid dust near beehives on windy days as you would with any powder. Read each label: suitability for organic growing is not the same as a whole-product organic licence number on every bag.\u003c\/p\u003e\n","products":[{"product_id":"organic-scottish-seaweed-kelp-meal-fertiliser","title":"Scottish Seaweed Fertiliser | Ascophyllum Kelp Meal","description":"\u003c!-- Dr Forest — Scottish Kelp Meal Product Page (v2 — Design System v1.0) --\u003e\n\u003c!-- Prefix: drf-km- (kelp meal).

Around the North Atlantic, including the Scottish coast, the dominant harvested species is knotted wrack, \u003cem\u003eAscophyllum nodosum\u003c\/em\u003e, an intertidal brown seaweed the literature describes as very effective at accumulating nutrients and minerals from seawater (Pereira et al., 2020). Most published research on seaweed in horticulture uses this species, so it is the one the figures below describe.\u003c\/p\u003e\n\u003cp\u003eAn extract pulls the soluble fraction out and discards the rest. A meal keeps the whole plant: the alginate cell walls, the fibre, the ash and the minerals bound in the tissue. That is why meal conditions soil and extract mostly does not. Craigie (2011), reviewing sixty years of seaweed use in agriculture, put it plainly: the old view that seaweed works simply because of the nutrients in it is no longer tenable. The action comes from the bioactive compounds, and in a meal they arrive slowly as it breaks down.

Low nitrogen, high phosphorus, useful potash — eleven named organic inputs, released as soil life works them, not as a soluble spike that crusts the pot and locks phosphorus to calcium or iron by Tuesday. Bone meal carries the slow phosphorus and a serious calcium fraction; gypsum adds more calcium in a pH-neutral form; chloride-free sulphate of potash steadies fruit quality and flower colour; alfalfa, flaxseed, plant nitrogen, kieserite, Scottish seaweed, humic and fulvic acid, zeolite and fermented biochar fill out the blend.

Too much nitrogen at flowering gives you leaf at the expense of buds. Don't chase a huge middle number, though: extra phosphorus on its own doesn't make more flowers, and in a slow-release blend the plant draws on far less of it in the first year than the bag suggests.

Blossom end rot is a calcium shortage at the fruit, and tomatoes and chillies are the crops most prone to it, so keeping calcium well supplied is a key part of preventing it. One honest caveat: blossom end rot is often less about how much calcium is in the soil and more about calcium reaching the fruit, which uneven or erratic watering disrupts. So feed cal-mag to keep the supply up, and water steadily and evenly alongside it — together they give you the best protection.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-cm-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-cm-faq5\"\u003eWill it change my soil pH?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eNo. Gypsum is calcium sulphate and is pH-neutral, so it adds calcium without lifting your soil pH.

That's why this one is built on gypsum (calcium sulphate, pH-neutral) and kieserite (a mined magnesium sulphate that holds far less water than Epsom salt), with a deliberate trace of boron and a little fulvic acid. Lime adds calcium too, but it also raises pH, which you don't want on neutral or alkaline soil. This is a soil product, not a spray.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-cm-faq-paa3\" type=\"checkbox\"\u003e\u003clabel for=\"drf-cm-faq-paa3\" class=\"drf-faq-q\"\u003eWhat happens if you use too much cal-mag?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eCalcium and magnesium compete with each other, and with potassium, for uptake, so piling on more can cause the very imbalance you're trying to fix. Boron is the bigger concern: plants need only a trace and too much is toxic, which is why this blend holds it at about 0.1% in slow-release form. Stick to the 10% rule with each feed. If you've overdone it, stop for a few weeks and water normally; in pots, a thorough watering through the compost helps carry the excess away.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-cm-faq-paa4\" type=\"checkbox\"\u003e\u003clabel for=\"drf-cm-faq-paa4\" class=\"drf-faq-q\"\u003eWhich plants benefit most from cal-mag?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eFruiting crops first: tomatoes, chillies and peppers, which are prone to blossom end rot when calcium doesn't reach the fruit. Then anything in containers, especially in peat-free compost or watered with rainwater, which carries almost no calcium or magnesium. Leafy crops that get tip burn, such as lettuce, and plants showing yellowing between the veins of older leaves (a sign of magnesium shortage) are also good candidates.

Blossom end rot is calcium failing to reach the flower end of fast-growing fruit (Ho \u0026amp; White, 2005), and calcium travels with water, so erratic watering can cause it even in calcium-rich soil. This formula carries 6.2% calcium; your part is watering evenly.

Equal N and K at 5% provides the balanced support for both. Phosphorus is intentionally modest at 3%: established woody plants have deep root systems and do not need high P, and excess phosphorus in the slightly acidic soils roses and most flowering shrubs prefer can interfere with micronutrient uptake. It is also the reason a low-P blend is the sensible choice around hydrangeas. This is a formula calibrated for how these plants actually grow — not derived from a general-purpose template.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-callout\"\u003e\n\u003cdiv class=\"drf-callout-label\"\u003eFeeding hydrangeas — an honest note on blue\u003c\/div\u003e\n\u003cp\u003eThe 5-3-5 ratio suits general flowering-shrub feeding, and it suits pink and white hydrangeas well. Blue is a different question, and it is worth being plain about it. Blue hydrangea colour depends on acidic soil and on aluminium being present in a plant-available form — it is not something an NPK ratio delivers. Phosphorus is the classic antagonist: it binds aluminium in the soil and takes it out of circulation, which is the usual reason blueing fails on a high-phosphorus feed. At 3% P this blend is modest and will not work against you. But if blue flowers are the goal, the limiting factor is your soil pH, not your fertiliser.

It reflects the nutritional reality of how roses and flowering shrubs grow — producing both a substantial woody structure and flowers simultaneously across a season that runs from March to October in the UK.\u003c\/p\u003e\n\u003ch3 class=\"drf-h3\"\u003ePotassium and fragrance — the direct relationship\u003c\/h3\u003e\n\u003cp class=\"drf-body\"\u003eFloral fragrance in roses is produced by volatile terpenoid and benzenoid compounds synthesised in the petal tissue. The terpenoid pathway — which produces the monoterpene geraniol, the sesquiterpene germacrene D, and related rose scent compounds — is potassium-dependent: K activates the enzymes and ATP-producing proton pumps required for terpenoid biosynthesis. Plants with inadequate K or with K supplied from chloride sources produce measurably lower concentrations of these compounds.\u003c\/p\u003e\n\u003cp class=\"drf-body\"\u003eEvery gram of K in this formula comes from chloride-free sources — Sulphate of Potash and Yorkshire Polyhalite. Muriate of potash (potassium chloride), the dominant K source in most garden fertilisers, delivers Cl⁻ ions that compete with K⁺ at cellular transporters and suppress secondary metabolite synthesis. The fragrance gap between roses fed with chloride-free K formulas and those fed with standard fertilisers is not subtle to anyone who grows both.\u003c\/p\u003e\n\u003ch3 class=\"drf-h3\"\u003eTriacontanol and bud count\u003c\/h3\u003e\n\u003cp class=\"drf-body\"\u003eTriacontanol is a naturally occurring fatty alcohol present in Alfalfa Meal, first identified as a plant growth regulator in the 1970s by Ries and Houtz. Its mechanism involves activation of adenylate cyclase, raising intracellular cAMP levels and triggering cascades that increase the rate of meristematic cell division and secondary metabolite synthesis simultaneously. In rose-specific research, triacontanol application consistently increases the number of axillary buds that break and develop into flowering laterals — translating directly into more flowers per plant per flush. Professional rose growers have used alfalfa meal as a component of feeding programmes for decades; this formula incorporates it as a core ingredient.\u003c\/p\u003e\n\u003ch3 class=\"drf-h3\"\u003eCalcium and petal quality\u003c\/h3\u003e\n\u003cp class=\"drf-body\"\u003eCalcium is a structural component of pectin in cell walls. In rose petals, adequate Ca means walls with sufficient rigidity to maintain petal form throughout the life of the flower — in the garden and after cutting. Low Ca produces petals that lose form rapidly, bruise easily, and absciss prematurely. Gypsum provides immediately available Ca; Yorkshire Polyhalite provides sustained Ca across 50–60 days. The combination ensures Ca is continuously available across the full flowering season, not just immediately after application.\u003c\/p\u003e\n\u003ch3 class=\"drf-h3\"\u003eNitrogen calibration\u003c\/h3\u003e\n\u003cp class=\"drf-body\"\u003eAt 5% N, this formula is at the moderate end of the range for established roses. This is deliberate. Excess nitrogen in roses produces the conditions that create serious problems: the sappy, soft new growth that aphids colonise; the dense, poorly aerated canopy that creates the humid microclimate in which black spot and powdery mildew spread most rapidly; and the vigorous vegetative growth that produces canes and leaves at the expense of bud initiation. The organic nitrogen fractions in this formula mineralise progressively over 6–8 weeks — there is no nitrogen spike, no flush of sappy growth, and no sudden drop. The plant receives a consistent, moderate N supply that sustains growth without overwhelming it.\u003c\/p\u003e\n\u003ch3 class=\"drf-h3\"\u003eSystemic Acquired Resistance via chitin\u003c\/h3\u003e\n\u003cp class=\"drf-body\"\u003eChitin — present in Mealworm Frass — is detected by pattern recognition receptors in plant cell membranes as a marker of fungal presence or insect feeding. Detection triggers a signalling cascade that activates Systemic Acquired Resistance pathways throughout the plant: salicylic acid accumulates, defence genes are upregulated, and the plant's capacity to mount rapid responses to subsequent pathogen attack is enhanced for weeks. For roses, which face consistent pressure from three major fungal pathogens, this priming effect is meaningfully useful — it does not prevent infection, but it significantly reduces the severity and spread of the diseases that inevitably arrive in a UK summer.\u003c\/p\u003e\n\u003ch3 class=\"drf-h3\"\u003eHydrangea flower colour — what actually controls it\u003c\/h3\u003e\n\u003cp class=\"drf-body\"\u003eSepal colour in \u003cem\u003eHydrangea macrophylla\u003c\/em\u003e is produced by a single anthocyanin, delphinidin-3-glucoside. On its own that pigment is pink. It turns blue only when it forms a complex with an aluminium ion, stabilised by co-pigments in the sepal tissue. So the question is never what pigment the plant makes — it always makes the same one — but whether aluminium reaches the sepal in a form that can complex with it.\u003c\/p\u003e\n\u003cp class=\"drf-body\"\u003eThat comes down to two things, and neither of them is the NPK ratio on the bag. The first is soil pH: aluminium is soluble and root-available below roughly pH 5.5, and progressively locked up as pH rises. The second is phosphorus. Phosphate reacts with aluminium in the soil to form insoluble aluminium phosphate, removing it from solution — which is why a high-phosphorus feed is the most common reason a blueing programme quietly fails. At 3% P this formula sits at the modest end and will not work against an acidification programme, but we are not going to claim more than that: \u003cstrong\u003ethis is a fertiliser, and it does not change flower colour.\u003c\/strong\u003e If blue is the goal, the intervention is soil pH, applied with a sulphur-based acidifier and maintained over time.

This is the signal that the plant has moved out of dormancy and root activity has resumed. Applying before bud break is premature: the organic nitrogen fractions require active soil microbial activity to mineralise, and cold soil slows this significantly. Apply around the drip line of the plant, water in well, and repeat every 4–5 weeks through to mid-August for roses. Flowering shrubs need fewer applications and should finish earlier — see the How to Use tab.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq2\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq2\"\u003eWhy is the NPK 5-3-5 rather than high potassium like a tomato feed?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eRoses and flowering shrubs produce both a large vegetative structure (canes, stems, leaves) and flowers simultaneously across a long season — they are not fruiting plants. Equal N and K at 5% provides balanced support for stem strength, leaf health and bloom production. Phosphorus at 3% is intentionally modest — established woody plants do not need high P, and excess phosphorus can compete with micronutrient uptake in the slightly acidic soils roses and most flowering shrubs prefer. Around hydrangeas a low-phosphorus feed is the sensible choice for a further reason, covered below.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq3\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq3\"\u003eHow often should I feed during the season?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eEvery 4–5 weeks from late March to mid-August for most garden roses. Once-blooming roses (ramblers, many old garden roses) need only two applications — one in March and one after flowering. Repeat-flowering roses benefit from three to four applications spread through the season. Flowering shrubs need less: two to three applications is normal, and mophead and lacecap hydrangeas should be finished by the end of June. Stop by mid-August for most rose varieties — late feeding encourages soft cane growth that is killed by autumn frosts.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq4\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq4\"\u003eCan I use it on all types of roses and flowering shrubs?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eYes — the 5-3-5 formula works for hybrid teas, floribundas, shrub roses (including English roses), climbing roses, ramblers, miniature roses and ground cover roses, and equally for hydrangeas, camellias, rhododendrons, azaleas, philadelphus, weigela, buddleja, lilac, viburnum and the general run of flowering shrubs. Because calcium comes from pH-neutral gypsum rather than lime, it is safe on the acid-loving shrubs as well. Feeding rates and timing vary by type — see the How to Use tab for the full table.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq5\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq5\"\u003eWill it improve the fragrance of my roses?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eYes — directly. Floral fragrance compounds in roses are potassium-dependent secondary metabolites. This formula uses exclusively chloride-free potassium (Sulphate of Potash and Yorkshire Polyhalite) — muriate of potash, the K source in cheaper fertilisers, suppresses these scent pathways. Alfalfa Meal adds triacontanol, which increases secondary metabolite production including fragrance compounds. The combination consistently produces stronger, more complex scent compared to plants given standard balanced feeds.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq6\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq6\"\u003eCan I use it on roses and shrubs in pots and containers?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eYes. For potted roses and shrubs, use 3–4g per litre of compost as an initial charge when potting, then top-dress at 2g per litre every 4 weeks. Always water very thoroughly after applying. The fermented biochar component helps retain potassium and other nutrients between waterings — particularly valuable for container roses and potted hydrangeas in free-draining terracotta pots that can dry quickly in summer.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq7\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq7\"\u003eWhen should I stop feeding in late summer?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eStop by mid-August for most garden roses. Late feeding encourages soft new cane growth that does not have time to lignify before the first frosts — this new growth is then killed back, leaving open wounds that can introduce disease. The exception is climbing roses on warm south-facing walls, which can be fed until early September as the wall warmth extends the hardening-off period. Flowering shrubs should stop earlier: mophead and lacecap hydrangeas after their June feed, most other shrubs by late July, so the wood has the rest of the summer to ripen.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq9\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq9\"\u003eWhat soil pH is best for roses and shrubs?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eRoses prefer slightly acidic to neutral soil, pH 6.0–7.0, with the ideal around 6.5. Below pH 6.0, manganese and aluminium can reach toxic levels; above pH 7.5, iron and manganese become locked up and yellow leaves appear. The humic and fulvic acid in this formula helps buffer micronutrient availability across a wider range, but soils significantly outside 6.0–7.0 should be adjusted with lime (too acidic) or sulphur (too alkaline). Camellias, rhododendrons, azaleas and hydrangeas want it lower, around 5.0–6.0. This blend is pH-neutral, so it will not push soil pH up underneath them, but it is a feed rather than an acidifier — for that use our \u003ca href=\"\/products\/sulphur-soil-acidifier\"\u003eSulphur Soil Acidifier\u003c\/a\u003e.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq10\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq10\"\u003eCan I use it alongside a liquid rose or shrub feed?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eIt is compatible with \u003ca href=\"\/products\/organic-seaweed-powder-concentrated-100-soluble-fertiliser-dr\"\u003eSeaweed Extract Powder\u003c\/a\u003e and other low-nutrient biostimulant liquids. If using a liquid rose or shrub feed as well, reduce the dry powder application to half rate or skip that cycle — combining two full-rate programmes pushes nitrogen above what the plant can use efficiently, resulting in soft, disease-prone growth. The dry powder is the better baseline for sustained nutrition through the season; liquid feeds work best as a boost just before the main June flush.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq11\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq11\"\u003eCan I use this as a hydrangea feed?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eYes. Feeding hydrangeas is one of the main uses this blend is built for. The 5-3-5 ratio gives them the nitrogen for leaf and stem and the chloride-free potassium that supports flower substance, and the phosphorus is deliberately low — which matters more for hydrangeas than for most plants. Feed mophead and lacecap types at bud break in late March and again in June, then stop, so the wood ripens before autumn and next year's buds survive the winter. Hydrangea paniculata and arborescens flower on the current season's growth and can take their second feed in late May instead. Rates are in the How to Use tab.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq12\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq12\"\u003eWill this turn my hydrangeas blue?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eNo, and we would rather say so plainly than sell you something on a hope. Blue hydrangea colour is not produced by a fertiliser. It happens when the soil is acidic — around pH 5.5 and below — and aluminium is present in a form the roots can take up and carry to the sepal, where it complexes with the plant's own pigment. Phosphorus is the classic antagonist here: it binds aluminium into insoluble compounds and takes it out of circulation, which is why high-phosphorus feeds are the usual reason a blueing programme fails. At 3% P this blend is modest and will not obstruct you, but the limiting factor for blue flowers is your soil pH, not your feed. If that is your goal, lower the pH with our \u003ca href=\"\/products\/sulphur-soil-acidifier\"\u003eSulphur Soil Acidifier\u003c\/a\u003e and see the \u003ca href=\"\/collections\/hydrangea-ericaceous\"\u003ehydrangea and ericaceous range\u003c\/a\u003e.

The calcium in this formula comes from gypsum, which is pH-neutral — unlike lime, it supplies calcium without raising soil pH, so it will not work against an acid soil the way a limed general fertiliser can. Feed at bud break and again immediately after flowering, which is when next year's buds are being set. Scatter it on the surface rather than forking it in: the roots of all three sit in the top few centimetres and are easily damaged. If the leaves are yellowing between the veins on an otherwise well-fed plant, the problem is soil pH locking up iron rather than a shortage of nutrients, and the fix is an acidifier.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq14\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq14\"\u003eWhen should I feed flowering shrubs, and how does it differ from roses?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eThe useful question is which wood the shrub flowers on. Shrubs that flower on last year's wood — mophead hydrangea, philadelphus, weigela, forsythia, deutzia — should be fed at bud break and again straight after flowering, then left alone so the new growth ripens. Shrubs that flower on this year's wood — hydrangea paniculata, buddleja, caryopteris, hardy fuchsia — are cut back hard in March and fed through spring and early summer, since they have a whole season's growth to build. Either way, flowering shrubs need fewer applications than a repeat-flowering rose and should finish earlier in the summer.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq15\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq15\"\u003eMy hydrangea has plenty of leaf but very few flowers. Is that a feeding problem?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eUsually not. On mophead and lacecap hydrangeas the most common cause is that the flower buds were lost — either pruned off in spring, or frosted, because these types carry next year's buds on the wood they made last summer. Cutting them back in autumn or early spring removes the flowers before they open. The second most common cause is too much shade. A high-nitrogen feed applied late in the season can contribute by pushing soft growth that never ripens, which is one reason this blend is moderate at 5% N and why we suggest stopping hydrangea feeding after June. If you want a hydrangea that tolerates hard spring pruning, grow a paniculata or arborescens type instead.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- PAA FAQ additions 2026-10-05 (proposed) --\u003e\n\u003cdiv class=\"drf-faq-item\"\u003e\n\u003cinput class=\"drf-faq-toggle\" id=\"drf-rfq-paa1\" type=\"checkbox\"\u003e\n\u003clabel class=\"drf-faq-q\" for=\"drf-rfq-paa1\"\u003eWhat is the best feed for roses?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003eA slow-release feed with nitrogen and potash in balance and modest phosphorus, because roses build canes and leaf at the same time as they flower. That's this 5-3-5, with chloride-free potash and calcium from gypsum, which doesn't raise soil pH. For most bush roses, scatter 80–100 g per m² over the root zone in late March as the buds break and again after the first flush, lightly worked in and watered. Stop by mid-August so new growth can harden before frost.

Then soil that drains but holds moisture, with a mulch of compost or well-rotted manure each spring, and a deep watering in dry spells rather than a daily sprinkle. Feed in late March and again after the first flush, deadhead repeat-flowerers through summer, and stop feeding by mid-August. Rose soil is happiest around pH 6.5.

Nitrogen, potassium and magnesium are pulled out of old leaves and sent to new growth when supply runs short. Calcium is different. It travels up the xylem in the transpiration stream and, once it has been laid down in a cell wall or a vacuole, it stays put. The phloem carries almost none of it (Hocking et al., 2016). So a tomato fruit, which transpires little, competes badly with leaves for calcium even when the soil has plenty.

A 2023 Latvian greenhouse trial of five commercial preparations, one of them a complexed calcium, sprayed weekly onto young fruit found none raised fruit calcium or cut the share of affected fruit (Karlsons et al., 2023).

It is used for blossom end rot, tip burn and general calcium feeding.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ac-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ac-faq2\"\u003eWill it fix blossom end rot on fruit that already has it?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNo. Once the black patch appears, that fruit is finished; the cells have already collapsed. Calcium sprays are for the fruit that has not set yet. Start when the first flowers open, spray the young fruit weekly, and sort your watering, because uneven watering is the biggest single trigger. The research on foliar calcium for blossom end rot is mixed, which is why we say even watering first, spray second.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ac-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ac-faq3\"\u003eWhy not just add lime or gypsum to the soil?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eMost garden soils already hold enough calcium. The problem is usually transport: calcium moves up the xylem with water and cannot be sent from leaves to fruit. If watering is erratic or the plant is growing fast, the fruit runs short even in calcium-rich soil. Lime also raises pH, and gypsum is a soil amendment rather than a spray. A soluble chelate lets you put calcium directly onto the tissue that needs it.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ac-faq4\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ac-faq4\"\u003eHow is this different from a calcium chloride spray?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eCalcium chloride is the cheap, standard foliar calcium. The difference is what comes with the calcium. Calcium chloride delivers chloride; this delivers 8% amino acid nitrogen and nothing else. The solution is mildly acidic rather than salty, and the amino acids are a food source for soil life when you drench. We do not claim it is absorbed several times better than a salt; that number appears in a lot of marketing and we could not find it in the literature.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ac-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ac-faq5\"\u003eIs chelated calcium suitable for organic growing?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eIt is made with organic ingredients: amino acids from enzyme digestion of non-GMO soybeans, and calcium from calcium carbonate.

A protein hydrolysate is protein cut back down into those units, either by enzymes at low temperature or by strong acid at high temperature. The method matters. Colla et al. (2015, \u003cem\u003eScientia Horticulturae\u003c\/em\u003e) note that acid hydrolysis destroys tryptophan, partly loses cysteine, serine and threonine, and racemises a portion of the rest from the L-form into the D-form, which plant enzymes cannot use. Enzymatic hydrolysis avoids all three problems.\u003c\/p\u003e\n\u003cp\u003eThe result is 84.8% total amino acids, 20% of it free amino acids and the rest short peptides. The 13% nitrogen is the nitrogen inside those amino acids, so it arrives as organic nitrogen rather than a soluble salt. du Jardin (2015) defines a biostimulant as anything applied to plants to improve nutrient use efficiency, stress tolerance or quality regardless of what nutrients it contains; a hydrolysate with 13% nitrogen sits on both sides of that line.

First, the total amino acids: this is 84.8%, with 20% as free amino acids and the rest short peptides. Second, the form: plant enzymes use the L-form, and enzymatic hydrolysis keeps the amino acids in that form, whereas acid hydrolysis at over 121 °C converts some of them. Third, what else comes with it: here that's 13% organic nitrogen, 8% potassium and 3,000 ppm amino-chelated iron, all fully soluble with no residue.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-aa-faq-paa3\" type=\"checkbox\"\u003e\u003clabel for=\"drf-aa-faq-paa3\" class=\"drf-faq-q\"\u003eHow often should I apply it?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eUse it a few times a season rather than as a weekly feed. For iron chlorosis or stress recovery, spray 2 g per litre onto the affected foliage every 7–10 days until the green returns. Otherwise, apply it at key moments such as transplanting, the start of flowering, or after heat, cold or drought. Make it up fresh each time, because the diluted solution starts to ferment if it's left.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- \/PAA FAQ additions --\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n","brand":"Dr Forest","offers":[{"title":"40g","offer_id":44719187919035,"sku":"DF-AMINO-40G","price":6.0,"currency_code":"GBP","in_stock":true},{"title":"120g","offer_id":44719187951803,"sku":"DF-AMINO-120G","price":8.99,"currency_code":"GBP","in_stock":true},{"title":"250g","offer_id":44719187984571,"sku":"DF-AMINO-250G","price":13.49,"currency_code":"GBP","in_stock":true},{"title":"500g","offer_id":44719188017339,"sku":"DF-AMINO-500G","price":21.99,"currency_code":"GBP","in_stock":true},{"title":"1kg","offer_id":44719188050107,"sku":"DF-AMINO-1","price":44.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0049\/8194\/8504\/files\/organic-amino-acid-bio-stimulant-fertiliser-fertiliser-golden-yellow-677.webp?v=1786553588"},{"product_id":"rock-phosphate-fertiliser-uk-31","title":"Rock Phosphate Fertiliser | 31% P₂O₅, 49% CaO, Micronised","description":"\u003c!-- Dr Forest — Rock Phosphate Fertiliser (Micro Cal-Phos) Product Page (v2 — Design System v1.0) — prefix drf-rp- --\u003e\n\u003cstyle\u003e\n  .drf-wrap *, .drf-wrap *::before, .drf-wrap *::after { box-sizing: border-box;

In the soil it releases phosphorus, which drives root growth, flowering and fruit fill, and calcium, which builds cell walls. This one is a soft rock phosphate micronised to a fine powder, analysing at 31% total P₂O₅ and 49% CaO, with up to 20% of the phosphorus in the formic-acid soluble form that counts for the coming season.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-rp-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-rp-faq2\"\u003eWhat is the difference between soft rock phosphate and ordinary rock phosphate?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eThe raw mineral is the same: natural calcium phosphate. The difference is grind. Standard rock phosphate is relatively coarse (100–500 microns or larger) and dissolves very slowly, releasing phosphorus over years. This soft rock phosphate is micronised, which exposes far more surface to soil water, root exudates and microbial acids, so substantially more phosphorus becomes available in the first growing season. The fine particle size also makes a liquid drench practical, which coarser rock phosphate cannot do.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-rp-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-rp-faq3\"\u003eMy tomatoes have purple leaves.

It is common in early spring when compost is cold and phosphorus is temporarily immobile. For the fastest correction, mix 1–2 g per litre and apply as a root zone drench to warm, moist compost; uptake slows right down when the roots are cold, so warming the plant up matters as much as the drench. New growth should improve in colour over 7–14 days.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-rp-faq4\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-rp-faq4\"\u003eWill rock phosphate help with blossom end rot?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eAt 49% CaO it is a good long-term calcium source for soil application. Blossom end rot, though, is more often caused by uneven watering interrupting calcium delivery to the fruit than by a shortage of calcium in the growing medium, so the first fix is consistent watering. For active blossom end rot, a water-soluble calcium such as \u003ca href=\"\/products\/liquid-gypsum\"\u003eLiquid Gypsum\u003c\/a\u003e works faster.

At the rates on this page, with a slow-release mineral rather than a soluble phosphate, the risk of complete suppression is low.

Bone meal can't.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-rp-faq-paa5\" type=\"checkbox\"\u003e\u003clabel for=\"drf-rp-faq-paa5\" class=\"drf-faq-q\"\u003eIs rock phosphate suitable for organic growing?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eIt's a single quarried mineral, ground with nothing added and no acid treatment, and it has no animal-derived ingredients.

Use 50 g as maintenance and up to 150 g when building new or depleted ground or correcting a phosphorus shortage. In established containers, top-dress at 0.2–0.5 g per litre of soil every 6–8 weeks. In new potting mixes, stir it through before planting. As a drench, mix the powder with a little water first, then top up and keep it stirred, because it settles.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- \/PAA FAQ additions --\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n","brand":"Dr Forest","offers":[{"title":"500g","offer_id":44828087353531,"sku":"DF-ROCKPHOS-500G","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"1.5kg","offer_id":44826364412091,"sku":"DF-ROCKPHOS-1.5","price":14.0,"currency_code":"GBP","in_stock":true},{"title":"3kg","offer_id":44826364444859,"sku":"DF-ROCKPHOS-3","price":24.0,"currency_code":"GBP","in_stock":true},{"title":"9kg","offer_id":46265253691579,"sku":"DF-ROCKPHOS-9","price":56.49,"currency_code":"GBP","in_stock":true},{"title":"15kg","offer_id":46265255329979,"sku":"DF-ROCKPHOS-15","price":92.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0049\/8194\/8504\/files\/organic-micro-cal-phos-31-phosphorous-micronised-rock-phosphate-445.webp?v=1785512767"},{"product_id":"organic-alfalfa-meal-pellets-2-5-0-3-2","title":"Alfalfa Meal Pellets | Organic Plant Feed","description":"\u003c!-- Dr Forest — Alfalfa Meal Pellets Product Page (v2 — Design System v1.0) --\u003e\n\u003c!-- Prefix: am · 4-tab layout --\u003e\n\u003cstyle\u003e\n  .drf-wrap *, .drf-wrap *::before, .drf-wrap *::after { box-sizing: border-box;

The whole shoot, leaf and stem, is cut, dried and milled. Because it is a legume, the crop fixes its own nitrogen from the air and stores it as protein in the leaf, which is where the 2.5% nitrogen in the meal comes from. In a 52-week incubation, Dion and colleagues (2020, \u003cem\u003eCanadian Journal of Soil Science\u003c\/em\u003e) measured alfalfa meal at 2.59% total nitrogen, which sits neatly against the 2.5% on our label.\u003c\/p\u003e\n\u003cp\u003eThere is no chemical processing. The pellet is the plant, dried and pressed. That matters because everything else the leaf contains comes along with the nitrogen: amino acids, potassium, trace minerals and the waxy cuticle that carries triacontanol.

All of it is locked in protein; none of it sits in the bag as soluble nitrate. Dion et al. found alfalfa meal mineralised 34–53% of its nitrogen over the year depending on the growing medium, with a short period of net immobilisation in the first week as microbes took up nitrogen to build their own biomass, and release levelling off after roughly 60 days.

It also suits tomatoes and cucumbers, soft fruit, leafy vegetables and lawns, and it's gentle enough to mix into seed and potting compost. It's a mild nitrogen feed (2.5-0.3-2), so heavy fruiting crops will still want a potash feed once they set fruit.

On vegetable beds use 100–150 g per m² before planting or as a side dressing every 4–6 weeks. For tomatoes and cucumbers, use 50–100 g per plant at planting and again at first flower set. For soft fruit, use 75–100 g per plant in early spring. In potting compost, mix in 5 g per litre before sowing or potting on.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-am-faq-paa3\" type=\"checkbox\"\u003e\u003clabel for=\"drf-am-faq-paa3\" class=\"drf-faq-q\"\u003eCan I add alfalfa pellets to my compost heap?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eYes. At 2.5% nitrogen, alfalfa is a nitrogen-rich \"green\" that helps a heap full of woody, carbon-rich material heat up and break down. Scatter a light sprinkling between layers as you add material; there's no precise rate. For feeding plants directly, though, it does more good in the soil, where the slow release over four to eight weeks feeds both the plant and the soil life.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-am-faq-paa4\" type=\"checkbox\"\u003e\u003clabel for=\"drf-am-faq-paa4\" class=\"drf-faq-q\"\u003eHow long do alfalfa pellets keep in the bag?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eKeep the bag sealed, cool and dry, and the pellets stay in good condition. Damp is the problem: pellets that get wet swell and start to break down in the bag, and the smell will tell you. Store the bag out of reach of dogs, who find the smell interesting.

A blend of igneous rock (the source of most of the potassium, magnesium and iron) and sedimentary rock (the main source of phosphorus and calcium), quarried, crushed, sieved and blended. No acid treatment, no chemical processing. The nutrients are held in the crystal lattices of minerals such as feldspar, mica, apatite and calcite, and they only become plant-available when those minerals dissolve.\u003c\/p\u003e\n\u003cp\u003eThat dissolution is what everything else on this page depends on. Harley and Gilkes (2000) reviewed the geochemistry of silicate rock powders and found that release depends on how far the soil solution is from equilibrium with the mineral, on the surface area exposed (which is why the powder is ground fine), and on biological activity in the root zone, which supplies the acids that attack mineral surfaces [1]. Swoboda, Döring and Hamer (2022) reached a similar conclusion: slow and inconsistent weathering held rock powders back historically, and results in any trial come down to the rock, the grind, the rate and the soil [2]. Best to be straight about that. Ground rock builds a reserve over seasons, and how fast depends on the soil it lands in.\u003c\/p\u003e\n\u003chr class=\"drf-sep\"\u003e\n\u003ch3\u003eFull mineral analysis\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eNutrient\u003c\/th\u003e\n\u003cth\u003eDeclared as\u003c\/th\u003e\n\u003cth\u003eAnalysis\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhosphorus\u003c\/td\u003e\n\u003ctd\u003eP₂O₅\u003c\/td\u003e\n\u003ctd\u003e5.10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePotassium\u003c\/td\u003e\n\u003ctd\u003eK₂O\u003c\/td\u003e\n\u003ctd\u003e5.00%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalcium\u003c\/td\u003e\n\u003ctd\u003eCaO\u003c\/td\u003e\n\u003ctd\u003e11.40%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnesium\u003c\/td\u003e\n\u003ctd\u003eMgO\u003c\/td\u003e\n\u003ctd\u003e3.10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSulphur\u003c\/td\u003e\n\u003ctd\u003eSO₃\u003c\/td\u003e\n\u003ctd\u003e4.20%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIron\u003c\/td\u003e\n\u003ctd\u003eFe₂O₃\u003c\/td\u003e\n\u003ctd\u003e3.30%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManganese\u003c\/td\u003e\n\u003ctd\u003eMn\u003c\/td\u003e\n\u003ctd\u003e0.05%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCopper\u003c\/td\u003e\n\u003ctd\u003eCu\u003c\/td\u003e\n\u003ctd\u003e0.01%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoron\u003c\/td\u003e\n\u003ctd\u003eB\u003c\/td\u003e\n\u003ctd\u003e0.01%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZinc\u003c\/td\u003e\n\u003ctd\u003eZn\u003c\/td\u003e\n\u003ctd\u003e0.003%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eTwo things stand out.

The three numbers are the NPK analysis: 0% nitrogen, 5.1% phosphorus as P₂O₅ and 5.0% potassium as K₂O. This one is a ground rock mineral rather than a processed salt, and it also carries 11.4% calcium (CaO), 3.1% magnesium (MgO), 4.2% sulphur (SO₃), 3.3% iron (Fe₂O₃) and traces of manganese, copper, boron and zinc.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-pk-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-pk-faq2\"\u003eWhy is there no nitrogen in it?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eBy design. Nitrogen drives leaf and stem growth. During flowering and fruiting, more nitrogen than the plant needs pulls energy into leaf, and in autumn it pushes soft growth at the wrong time of year. A zero-nitrogen feed lets you build phosphorus, potassium, calcium and magnesium whenever you like. During vegetative growth, pair it with a feed that does contain nitrogen, such as \u003ca href=\"\/products\/organic-all-purpose-fertiliser-4-4-4\"\u003eAll Purpose 4-4-4\u003c\/a\u003e.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-pk-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-pk-faq3\"\u003eIs this a PK booster?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNot in the sense most people mean. A PK booster is usually a soluble liquid or salt that gives a fast hit of phosphorus and potassium over a couple of weeks. This is ground rock. It releases over months as roots and soil microbes weather it, and it is far better suited to building a reserve in beds, borders and around fruit trees than to a quick pre-flower push.

Two things drive release: organic acids from plant roots, and weathering by soil bacteria and fungi. That is slower than a water-soluble feed but it lasts across a season and beyond. For the best chance of seeing an effect on this year's crop, apply 2–4 weeks before planting so weathering has started by the time roots arrive.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-pk-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-pk-faq5\"\u003eCan I use it on all plants, including tomatoes?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes.

Surviving that has driven it to accumulate an unusual density of protective compounds: alginates, fucoidans, laminarin, mannitol, betaines and phenolics. Applied to land plants, several of those compounds behave as signalling molecules rather than nutrients. This is the reason A. nodosum, rather than kelp or Sargassum, dominates the peer-reviewed biostimulant literature.\u003c\/p\u003e\n\n    \u003ch3\u003eAlginic acid is the number worth reading\u003c\/h3\u003e\n    \u003cp\u003eAlginic acid is the fraction that does most of the soil work.

At \u003cstrong\u003e19.38%\u003c\/strong\u003e, this material sits above the alginic acid content typically declared by mainstream Ascophyllum powders, which is the single most useful comparison figure when you are looking at competing seaweed products.\u003c\/p\u003e\n\n    \u003ch3\u003eThe potash is real, and it is not chloride-heavy salt\u003c\/h3\u003e\n    \u003cp\u003eSeaweed accumulates potassium from seawater.

If you grow under a certification scheme yourself, check with your certifier before adding any input to your programme.\u003c\/div\u003e\u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"drf-faq\"\u003e\n      \u003cinput type=\"checkbox\" id=\"drf-sw-faq2\"\u003e\n      \u003clabel class=\"drf-faq-q\" for=\"drf-sw-faq2\"\u003eIs seaweed feed high in nitrogen?\u003c\/label\u003e\n      \u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNo, and this is the most common misunderstanding about seaweed. The analysis here is 1.20% N, 0.89% P and 17.89% K₂O. Seaweed is potash dominant with very little nitrogen. If your plants are pale and hungry, they need a nitrogen source, not more seaweed. Use seaweed for rooting, stress tolerance and the potash contribution, and feed nitrogen separately.\u003c\/div\u003e\u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"drf-faq\"\u003e\n      \u003cinput type=\"checkbox\" id=\"drf-sw-faq3\"\u003e\n      \u003clabel class=\"drf-faq-q\" for=\"drf-sw-faq3\"\u003eWhat is the NPK of seaweed fertiliser?\u003c\/label\u003e\n      \u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eFor this soluble seaweed extract powder, 1.20 – 0.89 – 17.89 on the label, expressed as N, P and K₂O.

At garden dilution rates it will not replace a dedicated potash feed for a heavy-cropping tomato or a mature rose, but it does mean you are getting nutritional value alongside the biostimulant effect rather than the biostimulant effect alone.\u003c\/div\u003e\u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv class=\"drf-faq\"\u003e\n      \u003cinput type=\"checkbox\" id=\"drf-sw-faq5\"\u003e\n      \u003clabel class=\"drf-faq-q\" for=\"drf-sw-faq5\"\u003eIs seaweed fertiliser acidic or alkaline?\u003c\/label\u003e\n      \u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eThis powder is alkaline, with a pH close to 10 as supplied.

The bag or liquid already pushed leaf; potassium and water timing still decide how much sugar reaches the fruit; and a cheap brown bottle of “seaweed” is mostly water with a kelp story. You do not need more nitrogen. You need a signal the plant can use — and an honest feed beside it.\u003c\/p\u003e\n\n\u003cp\u003eDr Forest’s Brix+ is a concentrated liquid seaweed biostimulant, not a fertiliser in disguise. It carries triacontanol as the lead compound alongside cytokinins, gibberellins, auxins, betaines and mannitol, plus a declared trace-mineral load from kelp. Used little and often as a foliar spray or a root drench, it nudges the plant’s own growth signalling: more photosynthesis per hour of light, more sugar in the sap, steadier root establishment, and a buffer before a forecast frost, drought or heat. The name is the refractometer reading — degrees Brix — for dissolved solids in sap and fruit juice. Nitrogen is 0.26% and potassium 1.65% on purpose. That is the point: signalling, not another NPK can.\u003c\/p\u003e\n\n\u003cp\u003eDose economy is the other half of the product. At 2 to 2.5 ml per litre as a foliar, a litre bottle makes 400 to 500 litres of spray. If a litre of garden-centre seaweed only fills a watering can, you bought water. Raise frequency before you raise strength; the pathways respond to a regular dilute tickle, not a single heroic pour after the plant has already collapsed.\u003c\/p\u003e\n\n\u003cdiv class=\"drf-stats\"\u003e\n  \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e7\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eGrowth promoters\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e74\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eOcean trace minerals\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e2–2.5 ml\/L\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eFoliar rate\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e0.26% N\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eNot a nitrogen feed\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eWhat this bottle is for\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFruit that looks ripe but tastes bland\u003c\/strong\u003e — Brix+ nudges sap sugars; it does not replace a potassium-led crop feed.

Brix+ works at 2 to 2.5 ml per litre as a leaf spray, so a 1 litre bottle makes 400 to 500 litres of spray.

Tomatoes are one of the crops it's used on most. Spray the leaves at 2 to 2.5 ml per litre every 10 to 14 days. Brix+ nudges sap sugars, but you still need a potassium-led feed such as Organic Tomato Feed 3-4-6 to move those sugars into the fruit.

Zinc, manganese, iron and copper all lock up as soil pH rises, which is why deficiencies cluster on chalky and heavily limed ground. Zinc deficiency is the most widespread micronutrient problem in world crops, with high pH, free lime and high phosphate among the soil factors behind it (Alloway, 2009). Manganese deficiency is common on dry, well-aerated, calcareous soils (Alejandro et al., 2020).\u003c\/p\u003e\n\u003chr class=\"drf-sep\"\u003e\n\u003ch3\u003eComposition\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eElement\u003c\/th\u003e\n\u003cth\u003eContent (% w\/v)\u003c\/th\u003e\n\u003cth\u003eMain job in the plant\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZinc (Zn)\u003c\/td\u003e\n\u003ctd\u003e0.75%\u003c\/td\u003e\n\u003ctd\u003eEnzyme cofactor, leaf size, fruit set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManganese (Mn)\u003c\/td\u003e\n\u003ctd\u003e0.65%\u003c\/td\u003e\n\u003ctd\u003eWater-splitting in photosystem II\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIron (Fe)\u003c\/td\u003e\n\u003ctd\u003e0.60%\u003c\/td\u003e\n\u003ctd\u003eChlorophyll synthesis, electron transport\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCopper (Cu)\u003c\/td\u003e\n\u003ctd\u003e0.23%\u003c\/td\u003e\n\u003ctd\u003eLignin and cell wall strength\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoron (B)\u003c\/td\u003e\n\u003ctd\u003e0.16%\u003c\/td\u003e\n\u003ctd\u003ePollen viability, sugar transport, cell walls\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMolybdenum (Mo)\u003c\/td\u003e\n\u003ctd\u003e0.02%\u003c\/td\u003e\n\u003ctd\u003eNitrate reductase, nitrogen metabolism\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCobalt (Co)\u003c\/td\u003e\n\u003ctd\u003e0.01%\u003c\/td\u003e\n\u003ctd\u003eNeeded by nitrogen-fixing bacteria in legume nodules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eAlso contains fulvic acid, natural saponins and carbohydrate-based microbial promotants.\u003c\/em\u003e There is more on fulvic acid in \u003ca href=\"\/blogs\/the-dr-forest-blog\/what-is-fulvic-acid\"\u003ewhat is fulvic acid\u003c\/a\u003e.

Plants are known to need eight of them, and Micro-7 supplies six (iron, zinc, manganese, copper, boron and molybdenum), plus cobalt for the nitrogen-fixing bacteria in legume roots, all as a chelated liquid you dilute and apply as a leaf spray or a soil drench. It does not supply nitrogen, phosphorus or potassium, so use it alongside a normal fertiliser.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-m7-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-m7-faq2\"\u003eHow do I know if my plants need micronutrients?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYellowing between the veins points to iron, which shows on the youngest leaves first, or manganese; small, narrow or bunched new leaves to zinc; hollow stems in brassicas, or brown heart in swedes and turnips, to boron. Chalky, high-pH and heavily limed soils are the usual culprits because the metals lock up as pH rises.

Use when you see nitrogen deficiency symptoms: pale green or yellowing lower leaves, reduced growth rate, stunted development. The amino acid nitrogen is taken up through the leaf as free amino acids, so it is available without first being converted from nitrate or urea. This is a correction rate, not a maintenance rate — revert to 3 ml\/L once the deficiency is resolved.

The first is magnesium carbonate, milled to a fine particle size so it stays in suspension and presents a large surface area to soil moisture. Carbonate is only sparingly soluble, which is the point: it releases magnesium a little at a time as the soil water around it turns over. The second is fulvic acid, the smallest, most mobile fraction of humic substances. In this product it is both the suspension carrier and a chelator for the magnesium.\u003c\/p\u003e\n\u003cp\u003eFulvic acid is a low-molecular-weight organic acid with plenty of acid groups that bind metal ions. The case for it as a carrier is that magnesium held in a fulvic complex should cross the waxy leaf cuticle and the root cell membrane more readily than a bare ion.

Tomatoes in pots on a high-potash feed are the classic case; \u003ca href=\"\/blogs\/the-dr-forest-blog\/why-are-my-tomato-leaves-turning-yellow\"\u003eour guide to yellow tomato leaves\u003c\/a\u003e walks through telling the causes apart.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-lm-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-lm-faq3\"\u003eIs this better than Epsom salt?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eDifferent job. Epsom salt is fully soluble, so the whole dose is available straight away and then moves on with drainage water; it also brings sulphur. This suspension releases from carbonate particles over weeks and comes with a fulvic acid carrier that helps uptake through leaf and root. There is nothing to weigh out; you shake the bottle and measure it into the can. For a foliar spray or feeding a few pots, use this. For correcting a whole bed cheaply, use a soluble magnesium sulphate such as our \u003ca href=\"\/products\/kieserite-magnesium-sulphate-fertiliser\"\u003eKieserite\u003c\/a\u003e.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-lm-faq4\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-lm-faq4\"\u003eCan I use it as a magnesium foliar spray on tomatoes and roses?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes, that is its main use. Mix 3–6 ml per litre, spray both leaf surfaces early morning or late evening, and repeat every 2–4 weeks through the growing season. For a plant that is visibly deficient, use the 6 ml foliar rate together with a 10 ml per litre drench every 2–3 weeks until the symptoms resolve.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-lm-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-lm-faq5\"\u003eWhat does the fulvic acid do?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eThree things. It keeps the micronised particles in suspension so the bottle stays usable. It binds the magnesium in an organic complex, which is meant to help it into the leaf and the root.

But blossom end rot is mainly a water-supply disorder: calcium reaches the fruit with water, and the rot is thought to start when delivery falls behind (Ho \u0026amp; White, 2005). For severe or recurring cases, supplement with Dr Forest Liquid Gypsum as a root drench every 2–3 weeks once fruit is setting.

When 166 consumers rated fruit from 35 varieties and breeding lines, sweetness and strawberry flavour intensity drove how much they liked it: total sugars explained nearly half the variation, and sourness made no measurable difference (Schwieterman et al., 2014).\u003c\/p\u003e\n\u003ch3\u003eWhy a 3-2-7 ratio for strawberries\u003c\/h3\u003e\n\u003cp\u003ePotassium is sometimes called the quality element: it runs enzymes in photosynthesis and regulates the stomata, and without enough of it the plant makes and uses less sugar (Hasanuzzaman et al., 2018). Strawberry plants short of it give shrivelled, poorly coloured, pulpy fruit (Taghavi et al., 2019). Nitrogen cuts both ways: more yield, but lower sugars in one of two varieties in a Florida trial (Agehara, 2021).

The first and biggest, 10, is nitrogen, the nutrient that makes grass grow thick and green. The other two feed the roots and toughen the grass against drought and wear. What makes this feed different is where the nitrogen comes from: instead of a harsh chemical salt, it is a natural protein made from fermented plant sugars (molasses — the dark syrup left over from making sugar). Grass takes it up fast for a quick green, but because it is a gentle, low-salt protein rather than a soluble salt, it won't scorch the lawn, and it feeds steadily instead of dissolving and rushing straight through after the first heavy rain.\u003c\/p\u003e\n\u003cp\u003eMost lawn feeds only colour the grass. This one also feeds the living soil underneath, using natural conditioners drawn from a soft, ancient form of brown coal. They wake up the tiny life in the soil that does the real work of feeding your grass, so a tired lawn slowly comes back to health rather than just getting a quick coat of green. And it is a feed, not a weed-and-feed: there is no weedkiller in it, just food for the grass and the soil.\u003c\/p\u003e\n\u003cdiv class=\"drf-callout\"\u003e\n\u003cspan class=\"drf-callout-title\"\u003eSafe for pets, children and wildlife\u003c\/span\u003e\n\u003cp\u003eThere's no weedkiller and no pesticide in the bag — just food for the grass and the soil.

Roughly half the nitrogen is ready for the grass within the first two weeks, so you see a green-up fast. The difference from a cheap chemical feed is what happens next: the rest feeds steadily over the following weeks, and because the nitrogen is a natural protein and not a salt, you get that speed without the burn, the quick fade, or the feed washing away in the rain.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-ln-faq4\" type=\"checkbox\"\u003e\u003clabel for=\"drf-ln-faq4\" class=\"drf-faq-q\"\u003eWill it burn or scorch my lawn?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eIt is very unlikely to.

Water it in, unless rain is due in a day or two.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-ln-faq-paa2\" type=\"checkbox\"\u003e\u003clabel for=\"drf-ln-faq-paa2\" class=\"drf-faq-q\"\u003eGranular or liquid lawn feed: which should I use?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003e\u003cp\u003eThis granular feed goes down every six to eight weeks from mid-spring to the end of summer, at 45 to 60 g per square metre, and feeds steadily in between.

MAGNESIUM AND TRACE ELEMENTS: STRIPPED OUT.                        --\u003e\n\u003c!--    The 5-2-5 draft claimed \"+ magnesium and trace elements\". The      --\u003e\n\u003c!--    published spec for the 7-2-3 grade does not list magnesium (the    --\u003e\n\u003c!--    Mg-enriched grades in that range are the 6-2-3 Vegaline types).    --\u003e\n\u003c!--    Every Mg and trace-element claim has been removed rather than      --\u003e\n\u003c!--    carried across on assumption. Check the label\/spec sheet: if Mg    --\u003e\n\u003c!--    and trace are confirmed, search this file for \"MG-REINSTATE\" and   --\u003e\n\u003c!--    put them back in the four marked places.                           --\u003e\n\u003c!-- --\u003e\n\u003c!-- 2. APPLICATION RATE: DERIVED, NOT PUBLISHED BY THE MAKER.             --\u003e\n\u003c!--    ~7.5 ml product per m2 per feed = ~0.53 g N\/m2, ~3.5 g N\/m2\/year   --\u003e\n\u003c!--    over 7 feeds. Assumes 7% N w\/v (70 g N\/litre). If the analysis is  --\u003e\n\u003c!--    w\/w and the density is ~1.2 kg\/l, the true figure is ~6 ml\/m2 and  --\u003e\n\u003c!--    every coverage number below improves by roughly 20%. Sanity check: --\u003e\n\u003c!--    the maker's own agricultural rate for this grade is 30-50 l\/ha     --\u003e\n\u003c!--    fortnightly = 3-5 ml\/m2 per application, i.e. 6-10 ml\/m2 a month.  --\u003e\n\u003c!--    The rate here sits inside that band.

Its nitrogen, phosphorus and potassium are recovered from plant material and held in solution, so the grass can use them straight away. It greens a lawn quickly, the way a mineral feed does, but at a fraction of the salt. That means far less risk of scorching the grass, and a feed that is kinder to the soil and the life underneath it.\u003c\/p\u003e\n\u003cp\u003eThe 7-2-3 ratio is built for turf. Grass is grown for its leaves, not its flowers or fruit, and leaves run on nitrogen, so a lawn wants a feed that leads with N and keeps phosphorus low. That is exactly what this is: seven parts nitrogen to two of phosphorus and three of potassium, with the potassium there to toughen the plant and help it stand up to drought, wear and cold.\u003c\/p\u003e\n\u003cp\u003eIt is made without mining and without fossil-fuel nitrogen.

In one turfgrass trial, three amino acids applied to creeping bentgrass were absorbed about as well as urea, the synthetic standard, with uptake across all the nitrogen sources tested running between 31% and 56% within eight hours (Stiegler et al., 2013). That study measured uptake through the leaf on a golf green rather than through the roots of a home lawn, so read it as evidence that soluble organic nitrogen is genuinely usable by grass, not as a prediction of what any one lawn will do.\u003c\/p\u003e\n\u003cp\u003eThe gentleness comes down to salt. It is the salt in concentrated feeds, not the nitrogen itself, that scorches a lawn when feed goes on too heavily or onto dry grass.

Visually: hollow or brown heart in swede and beetroot, hollow stem in cauliflower and broccoli, corky patches on apple and pear, flowers dropping without setting fruit, and distorted or brittle new growth.

The gap between enough and too much is narrower for boron than for any other essential nutrient. Weigh the dose, apply once per bed per season, and do not combine with another boron-containing feed.

Those products settle, need agitating, and have to dissolve in the soil before a root can take anything up. This feed is a true solution. The potassium is already dissociated as K⁺, which is the only form a root hair or a leaf cuticle can absorb. There is no dissolution step to wait for.\u003c\/p\u003e\n\u003cp\u003eThat is what makes the same bottle work as a foliar spray. Foliar uptake happens through cuticular pores measured in nanometres. A suspended particle cannot pass, but an ion in solution can.

Sustained heavy potash feeding can therefore induce magnesium deficiency even where soil magnesium is adequate, showing as interveinal yellowing on older leaves. This is the single most common self-inflicted problem in a long high-potash tomato season, and the reason a calcium and magnesium source belongs in the programme alongside a potash feed rather than after it.\u003c\/p\u003e\n\u003ch3\u003eChloride and the source of your potash\u003c\/h3\u003e\n\u003cp\u003eChloride is a micronutrient, so plants need a little. The problem is dose. Muriate of potash is close to half chloride by weight, so a season of potash feeding in a container can deliver chloride well beyond the micronutrient requirement. Chloride is highly mobile and osmotically active, so it raises the salt load of the root zone and competes with nitrate uptake at the root surface (Xu et al., 2000). In open ground on free-draining soil, winter rainfall flushes it out. In a grow bag or a 10-litre pot, it does not. Tomatoes, strawberries, potatoes and beans are the crops where chloride sensitivity shows earliest, which is unfortunate, because those are also the crops gardeners feed the most potash to. It is worth knowing which potassium source you are actually using.\u003c\/p\u003e\n\u003chr class=\"drf-sep\"\u003e\n\u003ch3\u003ePlant-derived rather than mined\u003c\/h3\u003e\n\u003cp\u003eThe potassium here is plant-derived, with the feedstock drawn partly from agricultural residual streams. Conventional potash is mined, refined and freighted a long way before it reaches a British garden. Plant-based nutrient sources avoid that entirely, and the literature on bio-based fertilisers describes them as a credible route to reducing the extraction footprint of fertiliser production (Chojnacka et al., 2020).\u003c\/p\u003e\n\u003cp\u003eOne honest consequence: because the feedstock is natural plant material, the nutrient content varies slightly between batches.

Above about pH 7 it precipitates with calcium as increasingly insoluble calcium phosphates. Below about pH 5.5 it binds to iron and aluminium oxides. The window of maximum availability is narrow — roughly pH 6 to 7 — and even inside it, phosphate moves through soil by diffusion alone, at rates measured in millimetres. A root does not find phosphate; phosphate has to be within a millimetre or two of a root hair.\u003c\/p\u003e\n\u003ch3\u003eWhat phosphorus does inside the plant\u003c\/h3\u003e\n\u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e01\u003c\/span\u003e\n\u003ch4\u003eEnergy transfer\u003c\/h4\u003e\n\u003cp\u003eEvery energy transaction in a plant cell runs through ATP, and the phosphate groups are the energy carrier.

Broadcasting dry phosphate across a bed maximises that contact and therefore maximises loss.

At pH 3.5 to 4.5 the applied solution briefly lowers pH in the immediate root zone, which is the same trick roots themselves use — root exudation of organic acids to solubilise bound phosphate is a well-described mechanism (Hinsinger, 2001).\u003c\/p\u003e\n\u003ch3\u003eA finite resource, and a plant-derived alternative\u003c\/h3\u003e\n\u003cp\u003ePhosphate rock is a non-renewable mineral resource with no substitute in agriculture, concentrated in a small number of countries.

It sits at the centre of the chlorophyll molecule, which is why deficiency shows as yellowing. The plant is dismantling chlorophyll in old leaves to move the nitrogen to new growth. That mobility is diagnostic: nitrogen deficiency always appears on the oldest leaves first, where iron or sulphur deficiency appears on the newest (Marschner, 2012).\u003c\/p\u003e\n\u003cp\u003eIt is also the nutrient most easily overdone. Excess nitrogen produces large, soft, thin-walled cells that are more attractive to aphids, more susceptible to fungal problems and slower to ripen. The advantage of a peptide-based nitrogen source is that release is somewhat buffered by the need for partial microbial processing, which softens the peaks that a soluble nitrate salt produces.\u003c\/p\u003e\n\u003ch3\u003eSodium, chloride and container growing\u003c\/h3\u003e\n\u003cp\u003eThe formulation is free of sodium and chlorine. In open ground this matters little. In pots, grow bags and any recirculating system it matters a great deal, because there is no rainfall flushing the root zone. Sodium and chloride accumulate through a season of feeding, raise the osmotic load at the root surface and reduce water uptake. The plant then behaves as though it is short of water while sitting in wet compost.\u003c\/p\u003e\n\u003ch3\u003ePlant-derived rather than manufactured\u003c\/h3\u003e\n\u003cp\u003eIndustrial nitrogen fixation through the Haber-Bosch process consumes roughly 1% to 2% of global energy production.

Push one hard and you suppress the others. This is real and well documented, but it does not support the older Base Cation Saturation Ratio theory, which held that soils should be balanced to fixed cation percentages. That framework has not survived testing. Sufficiency of each nutrient matters far more than the ratio between them (Kopittke and Menzies, 2007).\u003c\/p\u003e\n\u003cp\u003eThe practical version is simpler.

That has three consequences. Uptake is immediate, because roots and leaf cuticles absorb ions rather than particles. Nothing settles out in the bottle. And the same product can be used as a foliar spray, because foliar uptake happens through cuticular pores measured in nanometres, far too small for suspended mineral particles.\u003c\/p\u003e\n\u003ch3\u003eOrganic and mineral feeding read honestly\u003c\/h3\u003e\n\u003cp\u003eAcross 537 experiments in grasslands and croplands, organic fertilisation raised aboveground biomass by 56% against 42% for mineral fertilisation, and only the mineral treatments reduced plant diversity (Shi et al., 2024). A separate synthesis of 7,859 paired observations from 551 field experiments found fertiliser lifted crop yield by 30.9% and nutritional quality by 11.9%, with potassium, magnesium and micronutrients doing much of the quality work, and combined organic plus mineral inputs performing best of all (Ishfaq et al., 2023). Vegetables were the most responsive crop group in that dataset.\u003c\/p\u003e\n\u003cp\u003eThat last finding is the argument for this feed rather than a straight NPK.

The usual cause is a balanced feed continued past first fruit set. Nitrogen promotes vegetative growth, and a plant given the option will keep growing rather than ripening. Dropping nitrogen and raising potassium is how you tell it to change priority.\u003c\/p\u003e\n\u003cp\u003eThe same logic applies to flowering ornamentals.

In open ground rainfall flushes chloride through. In a grow bag it does not, and tomatoes, strawberries and potatoes are all measurably chloride-sensitive (Xu et al., 2000).

Between 15 and 35% of the magnesium in a leaf is committed to chlorophyll; the rest activates enzymes and stabilises ribosomes in the cytoplasm (Marschner, 2012). When supply runs short, the plant strips magnesium out of its oldest leaves and moves it to the growing tip. That is why deficiency shows as yellowing between the veins on the \u003cem\u003elower\u003c\/em\u003e leaves first while new growth still looks healthy.\u003c\/p\u003e\n\u003cp\u003eThe damage starts before the yellowing does. Cakmak and Kirkby (2008) showed that magnesium shortage blocks sugar export from the leaf well before any visible symptom appears. Sugars accumulate, photosynthesis backs up, and surplus light energy generates reactive oxygen species that bleach the tissue. A plant can be losing yield for weeks while still looking green.\u003c\/p\u003e\n\u003chr class=\"drf-sep\"\u003e\n\u003ch3\u003eHow magnesium behaves in soil\u003c\/h3\u003e\n\u003cp\u003eMagnesium is a divalent cation held on clay and organic matter, but it binds more weakly than calcium and carries a larger hydration shell, so it sits further from the exchange surface. Gransee and Führs (2013) identify this as the reason magnesium leaches more readily than any other major cation. On sandy or free-draining ground, a wet UK winter strips a meaningful fraction of exchangeable magnesium out of the root zone.\u003c\/p\u003e\n\u003cp\u003eUptake is competitive too. Potassium, calcium and ammonium all compete with magnesium at the root surface, and high concentrations of any of them suppress it (Senbayram et al., 2015). This is the trap most tomato growers fall into: a summer of high-potash liquid feed drives magnesium deficiency in a soil that has plenty of magnesium in it.\u003c\/p\u003e\n\u003ch3\u003eMechanisms of action\u003c\/h3\u003e\n\u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e01\u003c\/span\u003e\n\u003ch4\u003eChlorophyll assembly\u003c\/h4\u003e\n\u003cp\u003eMagnesium chelatase inserts magnesium into the protoporphyrin ring, the committed step of chlorophyll biosynthesis.

It is mined, dried and graded rather than chemically manufactured. As a garden fertiliser it supplies 25% MgO (15% magnesium) and 50% SO₃ (20% sulphur), both as sulphate, which is the form plant roots take up directly. Magnesium sits at the centre of the chlorophyll molecule; sulphur builds the amino acids cysteine and methionine.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ks-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ks-faq3\"\u003eWhat is the difference between kieserite and Epsom salts?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eWater of crystallisation, which changes the concentration and the format rather than the speed. Epsom salt is magnesium sulphate heptahydrate — seven water molecules, 9.8% magnesium, 710 g\/L soluble. Kieserite is the monohydrate — one water molecule, 15% magnesium, 393 g\/L soluble. Both are fully soluble sulphates and both act quickly. The practical split is format. Kieserite comes as a granule for broadcasting over soil and gives you half as much magnesium again per kilo; Epsom salt is a fine crystal that dissolves in seconds. If you want to spray kieserite you can, but it needs two to four hours in water and a strain first — see the liquid feed section under How to Use, which includes the conversion table for turning any published Epsom rate into a kieserite one.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ks-faq4\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ks-faq4\"\u003eHow much magnesium fertiliser do I need per square metre?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eFor most garden plants, 15–25 g\/m² once a year in spring. Potatoes and top fruit take the upper end at 25–30 g\/m². Leafy vegetables and ericaceous shrubs need less, around 15 g\/m². A level tablespoon is roughly 15 g.

Magnesium deficiency yellows the tissue between the veins while the veins themselves stay green, and it always starts on the older, lower leaves because the plant moves magnesium up to new growth. A uniformly pale leaf points to nitrogen. Yellow new leaves with green veins point to iron. A soil test giving a Magnesium Index settles it properly.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ks-faq6\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ks-faq6\"\u003eWill kieserite change my soil pH?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eNo. Magnesium sulphate is pH neutral in solution, which is the main reason to choose it over dolomitic lime.

Both are pH neutral and both are granular, so they spread in the same pass. It also sits happily alongside granular fertilisers. Two things to avoid: applying it in the same season as dolomitic lime, since both supply magnesium; and dissolving it into the same tank as any calcium feed, which precipitates calcium sulphate and takes both nutrients out of solution.

It is fully soluble at around 393 g\/L, so a foliar spray or a soil drench both work. The catch is time: a 2–5mm granule needs two to four hours in water, ideally started warm and stirred at both ends. Because this is mined rock rather than a refined salt, let the solution settle and decant or strain it before it goes in a sprayer. As a rule of thumb, kieserite carries about half as much magnesium again per gram as Epsom salt, so use roughly two-thirds the weight of any published Epsom rate — the standard 2% foliar solution works out at 13 g of kieserite per litre.

The humic and fulvic fractions are soil-first: dissolve and water them in, and they go on working between feeds. The seaweed plant food is the one you reach for during the season, on a fortnightly rhythm through the growing months, as a watered-on feed or a dilute spray on the leaf.\n\nWe would rather not overclaim for any of the three. Seaweed extracts have a reasonable evidence base as biostimulants; the humic fraction has a good one for cation exchange and nutrient retention. None of them replaces feeding the soil properly.\n\nHandcrafted in Stockport. Each carries its own dilution and application rate, unchanged in the trio.

As a standard root drench for vegetables, plants and pots, use ¼–½ teaspoon (about 1–2.5 g) per litre every 1–2 weeks while plants are growing. At transplanting, use ¼ teaspoon per litre and repeat after 7–10 days. For pale or sluggish plants, give ½ teaspoon per litre twice, 5–7 days apart, and you should see greening within 3–7 days.
