Plant Success Granular is a granular material containing mycorrhizal fungi that colonize roots and extend into the surrounding soil forming an essential link between plant and soil resources. About 90% of the worlds plant species form mycorrhizae with these beneficial ectomycorrhizal fungi. Working together, beneficial mycorrhizal and tricoderma fungi expand into the surrounding soil and greatly increase the root's ability to absorb water, nutrients, improve yields and plant health.
