Dr Forest's is an 18-species blend of 9 endomycorrhizal and 9 ectomycorrhizal fungi, milled to a fine powder so the spores sit in direct contact with the feeder roots, which is where colonisation actually begins.\u003c\/p\u003e\n\n    \u003cp\u003eModern growing strips this partnership out. Bagged compost is sterilised, peat-free mixes start with no native fungi, and pot-raised nursery stock is grown on high-phosphate feeds and fungicides that suppress colonisation. Take that plant out of its pot and into the garden and it has no fungal partner. That is why new trees stall in their first seasons, transplants sulk, and roses planted where roses grew before fall into replant disorder. Inoculating at the moment of planting puts the partner back.\u003c\/p\u003e\n\n    \u003cdiv class=\"drf-callout drf-callout-gold\"\u003e\n      \u003cspan class=\"drf-callout-title\"\u003eA plant-based alternative to bone meal at planting\u003c\/span\u003e\n      \u003cp\u003eA root inoculant for gardeners who would rather not reach for bone meal, fish blood and bone, or other slaughterhouse by-products when they plant.

They are a symbiosis around 450 million years old, in which fungi colonise plant roots and grow a network of ultra-fine threads (hyphae) out into the surrounding soil. 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. Phosphorus is the headline benefit, because it barely moves in soil: roots quickly strip the zone immediately around them, and hyphae bridge the gap to the phosphorus beyond.\u003c\/p\u003e\n\n    \u003cdiv class=\"drf-callout drf-callout-dark\"\u003e\n      \u003cspan class=\"drf-callout-title\"\u003eWhy spore viability is the only number that matters\u003c\/span\u003e\n      \u003cp\u003eIndependent testing has repeatedly found that many shop-bought mycorrhizal products contain too few living spores to do anything.

Species counts and propagule claims mean nothing if the spores are dead on arrival. Dr Forest buys this inoculant in small batches with fresh stock arriving every month, so the spores leave here fresh rather than after a year on a warehouse shelf, and every pouch carries an honest 9–12 month use-by because viability falls over time.

The real catch is product quality: independent testing has found that many shop-bought inoculants contain dead or too few spores, with fewer than 12% of commercial products in a 2025 meta-analysis producing both colonisation and a growth benefit. That's why spore viability matters more than any marketing claim. Dr Forest buys this inoculant in small batches with fresh stock in every month, so you're applying living spores, not old warehouse stock, and every pouch carries an honest 9–12 month use-by. It works best when applied at planting, on plants that form the partnership, in low-phosphate conditions.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-my-faq2\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-my-faq2\"\u003eIs mycorrhizal fungi good for all plants?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eNo. Around 80–90% of plants form the partnership and benefit; about 10–20% don't. Skip it on the brassica family (cabbage, kale, broccoli, cauliflower, sprouts, turnip, radish), on beets and spinach, and on ericaceous plants (blueberries, cranberries, rhododendrons, azaleas, heathers). On those it gives no benefit, so save it for plants that will use it.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\n    \u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-my-faq3\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-my-faq3\"\u003eHow do I use a mycorrhizal inoculant?\u003c\/label\u003e\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eApply it at planting, in direct contact with the roots.
