The plant supplies sugars from photosynthesis; the fungi return phosphorus, water, nitrogen and trace elements gathered from a soil volume many times larger than the roots could explore alone.

Muriate of potash (potassium chloride) carries 47% chloride, which can accumulate in soil and damage sensitive crops. Sulphate of potash is almost chloride-free and adds 18% sulphur. For container growing, tunnel crops and chloride-sensitive plants like tomatoes, strawberries and potatoes, sulphate of potash is the safer, better-quality choice.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-sp-faq2\" type=\"checkbox\"\u003e\u003clabel for=\"drf-sp-faq2\" class=\"drf-faq-q\"\u003eIs sulphate of potash suitable for organic growing?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eYes.

Potassium sulphate is water-soluble, though the granulate dissolves more slowly than a fine grade. Stir well, or dissolve in warm water and let it stand for a few minutes.

It reflects the nutritional reality of how roses 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\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\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\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\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\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\n \u003ch3 class=\"drf-h3\"\u003eReferences\u003c\/h3\u003e\n \u003cul class=\"drf-refs\"\u003e\n \u003cli\u003eRies, S. \u0026amp; Houtz, R.

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. Stop by mid-August for most varieties — late feeding encourages soft cane growth that is killed by autumn frosts.\u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq-item\"\u003e\n \u003cinput type=\"checkbox\" class=\"drf-faq-toggle\" id=\"drf-rfq4\"\u003e\n \u003clabel class=\"drf-faq-q\" for=\"drf-rfq4\"\u003eCan I use it on all types of roses?\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.

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.

It formed during the Permian period when a vast shallow ocean — the Zechstein Sea — evaporated under hot, arid conditions across what is now northern Europe. As the water retreated, dissolved minerals concentrated into dense crystalline layers and were sealed underground for 260 million years. The world's largest known deposit sits beneath North Yorkshire, estimated at over two billion tonnes.\u003c\/p\u003e\n\u003cp\u003eThis polyhalite is extracted from Boulby Mine on the North Yorkshire coast — over 1,200 metres beneath the North Sea. It undergoes no chemical separation or industrial refining. Just mining, crushing, screening and granulation. That minimal processing gives it one of the lowest carbon footprints of any commercially available fertiliser at roughly 0.034 kg CO₂ per kg of product.\u003c\/p\u003e\n\u003cp\u003eWant the full background — how polyhalite formed, how it's mined and how it compares to other potash sources?

It formed 260 million years ago when the Zechstein Sea evaporated, concentrating dissolved minerals into dense crystalline layers beneath what is now North Yorkshire. It supplies four macronutrients — potassium, calcium, magnesium and sulphur — all as sulphates, with virtually zero chloride. It's mined, crushed and granulated with no chemical processing.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-pl-faq2\" type=\"checkbox\"\u003e\u003clabel for=\"drf-pl-faq2\" class=\"drf-faq-q\"\u003eWhat is polyhalite used for?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003ePolyhalite is used as a base mineral fertiliser to supply potassium, calcium, magnesium and sulphur — the four nutrients most often stripped out of containers, raised beds and intensively cropped soil. Gardeners use it as a chloride-free potash source, for tomatoes and other chloride-sensitive crops, for lawns and turf, and for breaking up heavy clay. It carries no nitrogen or phosphorus, so it's paired with an NPK feed for complete nutrition.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-pl-faq3\" type=\"checkbox\"\u003e\u003clabel for=\"drf-pl-faq3\" class=\"drf-faq-q\"\u003eWhat crops benefit most from polyhalite?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eCrops with high calcium, potassium and sulphur demand respond most strongly.

Where SOP gives you potash plus sulphur and nothing else, polyhalite gives you potash plus calcium, magnesium and sulphur in one product — so it covers more ground per application if your soil needs more than just potassium.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput id=\"drf-pl-faq6\" type=\"checkbox\"\u003e\u003clabel for=\"drf-pl-faq6\" class=\"drf-faq-q\"\u003eHow is polyhalite different from sulphate of potash?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eSulphate of potash (SOP) delivers 50% K₂O and 18% S — two nutrients.

No blood meal, bone meal, feather meal, hoof or horn. It is approved for use in certified organic growing systems under EU and UK organic standards, as it is a natural plant material with no chemical processing.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-am-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-am-faq2\"\u003eCan alfalfa meal burn my plants?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNo. Alfalfa meal is one of the safest organic fertilisers to use around plants, including seedlings and young transplants. Unlike fast-release nitrogen sources such as blood meal or synthetic feeds, alfalfa's nitrogen is locked into protein structures and releases only as soil microbes break it down. This biological gating means the plant cannot receive more nitrogen than its biology can process.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-am-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-am-faq3\"\u003eIs alfalfa meal a good fertiliser for roses?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes — alfalfa meal has been used by dedicated rose growers for decades and is considered one of the best organic amendments specifically for roses. The key reason is triacontanol, a naturally occurring plant growth stimulant in the waxy cuticle of alfalfa leaves. Research has linked triacontanol to increased new cane production, improved flowering, and greater overall plant vigour. Apply 100–150g per bush in early spring when soil temperature exceeds 10°C, and repeat after the first flush.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-am-faq4\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-am-faq4\"\u003eWhat is triacontanol and why does it matter?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eTriacontanol (C₃₀H₆₂O) is a naturally occurring fatty alcohol found in the waxy cuticle of alfalfa leaves. First identified by Stanley Ries at Michigan State University in the 1970s, it measurably increases photosynthetic rate, chlorophyll content, root growth, and crop yield at vanishingly small concentrations. A 2020 meta-analysis confirmed positive effects across more than 40 crop species. No synthetic fertiliser contains it — it is unique to natural alfalfa sources.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-am-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-am-faq5\"\u003eHow long does alfalfa meal take to work?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eIn warm, moist soil above 12°C with active biology, meaningful nitrogen release begins within 1–2 weeks, peaking around weeks 2–4, with residual release continuing for 4–8 weeks total. In cooler early-spring conditions, breakdown is slower — but this is a useful feature, as the feed kicks in properly just as growing conditions improve. For faster results, brew the pellets into alfalfa tea (3–5 days steeping) and apply as a liquid drench.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-am-faq6\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-am-faq6\"\u003eHow much alfalfa meal should I use per plant?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eRoses and larger shrubs: 100–150g per bush.

Because magnesium is mobile in the plant, it is pulled from old leaves to supply new growth, so symptoms always appear on the lower and middle leaves first. In severe cases, leaves develop brown necrotic patches and drop prematurely. Tomatoes, peppers, roses, and citrus are particularly susceptible.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-mm-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-mm-faq2\"\u003eHow is Micro-Mag different from Epsom salt?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eEpsom salt (magnesium sulphate) is fully water-soluble and fast-acting but leaches rapidly — it needs frequent reapplication. Micro-Mag is micronised magnesium carbonate: it provides more sustained release, has a mild pH-buffering effect that helps acidic soils, and has a lower salt index. Epsom salt also provides sulphur, which is useful where both magnesium and sulphur are deficient — but for magnesium correction alone, Micro-Mag is more persistent and effective.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-mm-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-mm-faq3\"\u003eCan I use Micro-Mag as a foliar spray?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes — the micronised particle size allows it to be suspended in water and applied through a sprayer. Stir or shake the solution regularly during use as the particles will settle. Magnesium absorbed through the leaves is phloem-mobile and can be transported to wherever the plant needs it most. Foliar application is the fastest way to correct visible deficiency symptoms.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-mm-faq4\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-mm-faq4\"\u003eWhy do my tomatoes keep getting magnesium deficiency?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eTomatoes are heavy feeders with high potassium demand during fruiting. Most tomato feeds are potassium-rich, and potassium competes directly with magnesium for root uptake. The more potassium you apply, the more likely you are to induce magnesium deficiency — even in soil that contains adequate Mg. The solution is to supplement magnesium alongside your potassium-rich feed, not to reduce potassium. Micro-Mag as a fortnightly foliar spray during fruiting is an effective preventive approach.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-mm-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-mm-faq5\"\u003eWill Micro-Mag change my soil pH?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eMagnesium carbonate has a mild alkalising effect — it will gently raise the pH of acidic soils over time. This is a benefit in most cases, as magnesium deficiency is most common in acidic conditions. However, if you are growing acid-loving plants like blueberries or rhododendrons and want to avoid raising pH, use Micro-Mag as a foliar spray only — foliar application delivers magnesium to the plant without affecting soil pH.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-mm-faq6\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-mm-faq6\"\u003eIs Micro-Mag suitable for organic growing?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes.

Magnesium is directly responsible for the depth of green colour in turf. Deficient lawns appear pale and yellowish even with adequate nitrogen. Apply 50–80g per m² as a dry broadcast, or dissolve in water and apply with a watering can or sprayer.

Chitin is the key bioactive component: it triggers induced systemic resistance (ISR) in plants — activating the plant's own immune pathways against fungal pathogens, root-knot nematodes and foliar pests, before infection occurs. It also stimulates chitinase enzyme production, which directly degrades fungal cell walls (Poveda et al., 2019).\u003c\/p\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e03\u003c\/span\u003e\u003ch4\u003eSulphate of Potash (SOP)\u003c\/h4\u003e\n\u003cp\u003ePrimary immediate-release potassium and sulphur carrier.

Safe for children, pets, bees and pollinators once watered in.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ff-faq7\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ff-faq7\"\u003eWhy is the potassium level higher than most flower fertilisers?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eBecause the science says it should be. Marschner (2012) and Römheld \u0026amp; Kirkby (2010) identify potassium — not phosphorus — as the primary driver of flower colour, sugar transport to buds, drought tolerance and disease resistance in flowering annuals. The optimal K:N ratio for flowering annuals is 1.5:1 to 2:1 in soil solution. At 3-3-6, this formula delivers exactly 2:1. Most commercial bloom boosters prioritise phosphorus — a legacy of 1970s agronomy that modern mycorrhizal ecology has clearly refuted.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ff-faq8\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ff-faq8\"\u003eCan I mix this into compost when potting up?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes — and this is one of the most effective ways to use it. Add 4–5g per litre of compost (approximately 1 level teaspoon) when making up your potting mix. This pre-loads the substrate with minerals, biological life and humates before the plant goes in. Use 4g\/L for medium feeders like impatiens and begonias, and 5g\/L for heavy feeders like petunias and fuchsia.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ff-faq9\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ff-faq9\"\u003eWhy do I need to wear a dust mask?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eThe micronised mineral ingredients can produce fine airborne dust when poured. There is no toxic hazard, but inhaling any fine mineral dust repeatedly is not advisable. The simplest solution — and our recommended method regardless of dust — is to mix each dose with an equal volume of compost before applying. The microbial life in the compost immediately begins breaking down the organic fractions, accelerating nutrient availability to roots. It also cuts dust significantly. Apply outdoors or in a well-ventilated area and wear a basic mask when handling dry. Once applied and watered in, the product is completely safe for children, pets and wildlife.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ff-faq10\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ff-faq10\"\u003eI can see white or fluffy growth on the soil surface after applying — is this normal?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eCompletely normal, and a sign the formula is working. What you're seeing is microbial activity — soil bacteria and fungi colonising the organic ingredients and breaking them down into plant-available nutrients. This is the biological layer of the formula doing exactly what it is supposed to do. It is harmless to plants. If you find the appearance unsightly, apply the fertiliser as normal and then cover with a light layer of compost — this conceals the surface activity while allowing the microbial process to continue undisturbed beneath.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ff-faq11\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ff-faq11\"\u003eWhat is the difference between humic and fulvic acid?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eBoth are fractions of decomposed organic matter but they work differently. Humic acid has a larger molecular weight and operates in the soil — it chelates micronutrients including iron and manganese to keep them plant-available at the slightly alkaline pH typical of UK tap-water-irrigated containers. Fulvic acid has a much smaller molecular weight, is fully soluble across all pH ranges, and can penetrate root cell membranes directly. It acts as a natural biostimulant, increasing membrane permeability and improving the efficiency of nutrient uptake from the root zone.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ff-faq12\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ff-faq12\"\u003eCan I use this on dahlias in pots?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes — dahlias respond very well to the 3-3-6 formula, particularly when container-grown. A 2:1 K:N ratio drives flower head production and improves stem strength in taller cultivars. Apply at 4g per litre of pot volume — so 40g for a 10L pot, 60g for a 15L pot — mixed into the potting compost at planting, then top-dress at the same rate every 5–6 weeks through the flowering season.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n \u003c\/div\u003e\n\u003c!-- end panels --\u003e\n\u003c\/div\u003e\n\u003c!-- end tabs-wrap --\u003e\n\u003c\/div\u003e\n\u003c!-- end drf-wrap --\u003e\n\u003c\/div\u003e","brand":"Dr Forest","offers":[{"title":"1.5kg","offer_id":57443671572854,"sku":null,"price":11.5,"currency_code":"GBP","in_stock":true},{"title":"4kg","offer_id":57443671605622,"sku":null,"price":23.5,"currency_code":"GBP","in_stock":true},{"title":"9kg","offer_id":57443671638390,"sku":null,"price":44.0,"currency_code":"GBP","in_stock":true},{"title":"15kg","offer_id":57443671671158,"sku":null,"price":60.49,"currency_code":"GBP","in_stock":true},{"title":"30kg","offer_id":57443671703926,"sku":null,"price":120.0,"currency_code":"GBP","in_stock":true},{"title":"60kg","offer_id":57443671736694,"sku":null,"price":225.0,"currency_code":"GBP","in_stock":true},{"title":"120kg","offer_id":57443671769462,"sku":null,"price":420.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0049\/8194\/8504\/files\/Flower4.png?v=1773180810"}],"url":"https:\/\/www.drforest.co.uk\/collections\/rose-flower-fertilisers.oembed","provider":"Dr Forest","version":"1.0","type":"link"}
