Plant Success Granular is a mycorrhizal granular inoculum that consists of 13 carefully selected species of endomycorrhizae, ectomycorrhizae, and trichoderma fungal species. This granular material, which contains mycorrhizal fungi, colonizes roots and extends into the surrounding soil, forming an essential link between plant and soil resources. The all-purpose fertilizer in Plant Success Granular® gives these microbes a head start in feeding the newly establishing plant.
