Symbio Mycorrhizal Transplanter gives your plants the Mycorrhizal Advantage that can double the growth rates of young plants. Potting compost, fallow soil and nursery plants raised on fertiliser and fungicides do not contain essential mycorrhizae.
Our whole garden or allotment pack provides 8 species of common endo mycorrhizae and 7 species of ecto mycorrhizae that associate with nearly all plants; it also contains beneficial soil bacteria and fungi, zeolites and trace elements.
Application is easy just dust the powder onto seeds, bulbs, tubers or roots for a massively extended root system. (Does not work on brassicas or ericaceous plants) - Symbio UK
The beneficial fungii is something i've been using now since the summer, starting with dividing grasses and now with planting, its something i've seen used elsewhere and i'm positive about the results and the role in plays in encouraing better root formation. Something which our plants, grown in lower light levels than the rest of the UK can benefit from....after all anything which naturally encourages a plant to grow can't be bad. See here for the Symbio website, i think this cost me abotu the £20 mark for a bag delivered. I've probably used a bag on 100 plants.
Mycorrhizal fungi live in soil and colonize roots forming a biological link
between the plants and the soil. The fungus grows on or into the root and
extends hyphae into the soil. Mycorrhizae absorb water and nutrients from the
soil and introduce them into the root. Mycorrhizae can solubilise nutrients like
phosphate that are locked up in the soil. They effectively enlarge the root
system and its surface area from double to up to 1000 times so mycorrhizal
plants have access to much more nutrient and water than non mycorrhizal plants
to grow faster and larger. - Symbio UK
