It feeds the whole garden from one application every four to six weeks, and because it carries no blood, bone or fish, it has only a mild earthy smell. Handcrafted in small batches in Stockport.\u003c\/p\u003e\n\u003cp\u003eThe balanced ratio is deliberate. Equal nitrogen, phosphorus and potassium mirrors what diverse plants in active growth actually withdraw from the soil, rather than the high-nitrogen profile most all-purpose feeds inherit from farm research. The immediate mineral fraction feeds within 48 hours; the Cambridgeshire plant meals feed for 6–8 weeks; Yorkshire Polyhalite extends the tail to 60 days. Every nutrient arrives from more than one source, at different speeds.\u003c\/p\u003e\n\u003cp\u003eIt is also a proper alternative to fish, blood and bone for gardeners who want an organic feed without the animal inputs or the smell. Phosphorus and nitrogen come from plant meals, not slaughterhouse by-products, so it suits vegan growers and stays pleasant to use in pots, beds and near the back door — with far less appeal to the cats and foxes that dig where fish-based feeds have been spread.\u003c\/p\u003e\n\u003cdiv class=\"drf-stats\"\u003e\n\u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e6-6-6\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eBalanced NPK\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e100%\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eVegan\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003eLow\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eOdour\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e11\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eIngredients\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eWhat it does across the whole garden\u003c\/h3\u003e\n\u003cul class=\"drf-uses\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeep, dark foliage\u003c\/strong\u003e — sustained nitrogen from Cambridgeshire plant extracts builds chlorophyll without the flush-and-crash of soluble feeds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoots that anchor\u003c\/strong\u003e — three phosphorus sources at different release speeds keep root tips dividing from transplant through to harvest.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBigger flowers, better fruit\u003c\/strong\u003e — chloride-free potassium drives stomatal control and sugar transport for deeper flavour, stronger colour and higher bud count.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWalls that hold\u003c\/strong\u003e — four calcium sources, continuously supplied.

The formula delivers calcium, magnesium and potassium in an approximate 3:1:3 ratio. Calcium and potassium compete directly at root cation-exchange sites: if potassium is high and calcium low, K floods in and Ca is shut out, causing tip burn, blossom end rot and weak walls despite apparently adequate potassium. The 3:1:3 balance keeps calcium uptake going even when potassium demand peaks during fruiting, with magnesium at the lower position to meet the chlorophyll requirement without antagonising the other two.\u003c\/p\u003e\n\u003chr class=\"drf-sep\"\u003e\n\u003ch3\u003eWhy a plant-and-mineral feed has so little smell\u003c\/h3\u003e\n\u003cp\u003eThe pungency of fish, blood and bone is a direct result of its ingredients. Dried blood, bone meal and fish meal are animal proteins, and as soil microbes break those proteins down they release volatile amines and sulphur compounds — the source of both the strong smell and its appeal to cats, foxes and rodents. This formula contains no animal proteins. Its nitrogen comes from a plant protein concentrate and its phosphorus from calcined plant meal, neither of which produces that volatile breakdown profile.

Each application raises electrical conductivity, which opposes the water uptake that carries nutrients into the plant, and most liquid feeds contain no calcium at all — the one nutrient that is immobile and must be continuously present. Dry organic amendments side-step all of this: nutrients release only as microbial enzymes break them down, at a rate that tracks soil temperature and moisture, which is to say plant demand.

Fish, blood and bone is a three-ingredient animal blend with essentially one release speed, low and unbalanced potassium, little usable magnesium or sulphur, and a strong fishy smell that draws cats and foxes. Dr Forest All-Purpose uses eleven plant and mineral ingredients across three release speeds, with chloride-free potassium, four calcium sources and three magnesium sources, and only a mild earthy scent. It feeds the same broad range of plants, performs at least as well, and contains no slaughterhouse by-products.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq2\"\u003eIs it vegan?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eEntirely. Every ingredient is plant-derived or mineral. No blood, bone, feather, fish or manure. It is one of very few genuinely balanced all-purpose vegan fertilisers made in the UK, and the formulation choice predates any commercial consideration.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq3\"\u003eDoes it have a strong smell?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNo. Because it contains no blood, bone or fish meal, it has only a mild earthy smell rather than the strong odour of traditional organic feeds, and that fades once watered in.

Heavy feeders such as tomatoes, courgettes and brassicas every four weeks; medium feeders such as beetroot, leeks and soft fruit every five to six; light feeders such as peas, salad and lavender every six to eight.

The balanced 6-6-6 covers the nutritional baseline of vegetables, flowers, fruit, shrubs and ornamentals.

It delivers NPK quickly but does nothing for soil biology, carries no secondary nutrients or trace minerals, and degrades soil through salt accumulation.
