An even ratio of nitrogen, phosphorus and potash covers leaf, root and flower together, released slowly through soil biology so there are no salt spikes and no scorched roots. Dr Forest blends it by hand in Stockport from ten organic inputs, with slow-release phosphorus and calcium from bone meal and natural biostimulants from Scottish seaweed and alfalfa.\u003c\/p\u003e\n\u003cdiv class=\"drf-badge-row\"\u003e\n\u003cspan class=\"drf-badge drf-badge-green\"\u003eBalanced 4-4-4 NPK\u003c\/span\u003e \u003cspan class=\"drf-badge drf-badge-green\"\u003e10 Organic Inputs\u003c\/span\u003e \u003cspan class=\"drf-badge drf-badge-green\"\u003eVeg · Fruit · Flowers\u003c\/span\u003e \u003cspan class=\"drf-badge drf-badge-gold\"\u003eSlow \u0026amp; Steady Release\u003c\/span\u003e \u003cspan class=\"drf-badge drf-badge-green\"\u003ePots, Beds \u0026amp; Allotments\u003c\/span\u003e \u003cspan class=\"drf-badge drf-badge-dark\"\u003eHandcrafted in Stockport\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cp\u003eIt takes over from our Veg 4-4-4. Growers kept using that right across the plot rather than only for leafy growth, so we reformulated it as a true all-purpose feed — the same balanced 4-4-4 ratio, but a new recipe with some different ingredients chosen to suit the whole garden. The even ratio covers the majority of what UK gardeners grow, and the feeding guide simply matches the rate to how hungry each plant is.\u003c\/p\u003e\n\u003cp\u003eIt is a granular dry amendment — sprinkle it on or mix it in, with no dissolving, no measuring pH and no weekly liquid feeding. Because the nutrients come from organic meals and slow-release minerals rather than soluble salts, soil microbes release them at the pace the plant demands, building soil health rather than degrading it.

Light feeders prefer lean soil: peas, beans and other legumes (which fix their own nitrogen), carrots, parsnips, beetroot, onions, garlic, and Mediterranean herbs like rosemary and thyme. Most other crops — potatoes, salad, soft fruit, bedding and perennials — are medium feeders. Full rates for each group are on the How to Use tab.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq5\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq5\"\u003eCan I use it on tomatoes, roses and vegetables from one bag?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eYes — that is the point of an all-purpose feed. Tomatoes and roses are heavy feeders, so feed them at the upper rate every 2–3 weeks. As they come into flower and fruit you can add a potash-rich feed such as our Sulphate of Potash for bigger, better-quality fruit and blooms, though 4-4-4 will carry them well on its own.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq6\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq6\"\u003eWill it burn or scorch my plants?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eVery unlikely at the recommended rates. Because it feeds through slow microbial release rather than soluble salts, there are no nutrient spikes and a wider safety margin than synthetic feeds. Keep to the rates, water in after top dressing, and avoid piling it against stems.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq7\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq7\"\u003eIs it organic, and is it granular or powder?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eIt is made with organic ingredients and contains no synthetic chemistry.

It is a steady feed, not an instant green-up, so judge it over weeks rather than hours.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq10\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq10\"\u003eCan I mix it with other feeds or my own compost?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eYes. It works alongside home-made compost, leaf mould and worm castings, and pairs well with our seaweed and potash. If your compost is already rich, start at the lower rate or skip the soil-mix step and begin top dressing once the initial nutrients run down, usually after 2–4 weeks.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq11\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq11\"\u003eIs it safe for children, pets, bees and wildlife?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eIt is a natural soil feed with no synthetic pesticides, so it is not harmful to pollinators in normal use and supports a healthy garden ecosystem.

Give evergreens and conifers, box, yew, laurel and privet hedging, topiary, acers, hydrangeas, ferns and ornamental grasses a balanced feed in spring and early summer at the light-to-medium rate, scattered around the base and watered in. Ease off by late summer so growth hardens before winter. Acid-loving plants such as rhododendrons, azaleas and camellias do best on an ericaceous feed, though a light application here will not harm them.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ap-faq14\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ap-faq14\"\u003eWhere is it made and where do the ingredients come from?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\n\u003cdiv\u003eHandcrafted in small batches at our unit in Stockport, Greater Manchester, using British ingredients where possible, including Scottish seaweed.
