A raised bed describes where you grow, not which fungal partnership your plants can form. Identify the crop and growing medium. Put granules at the roots of compatible transplants rather than treating all bed occupants as equivalent.
Keep the context.
Biological compatibility, successful colonisation and a measurable plant response are different questions. The growing conditions matter, and general research is not a promise of a particular result with MegaMyco.
