The arbuscular mycorrhizal life cycle is closely connected with living roots. Viable fungal material can encounter a suitable host, develop structures in the root and extend hyphae into the surrounding medium. Conditions influence establishment; there is no single calendar that describes every association.
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.
