MegaMyco is applied as granules close to roots. It is not presented as a feed to add at every watering. Follow the directions on the pack and focus on the opportunity for root contact.
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.
