Trees use different mycorrhizal types. Many trees form arbuscular associations, while others, including many pines and oaks, rely on ectomycorrhizal fungi or have more complex patterns. “For trees” is not a universal compatibility claim. Identify the species and required fungal association before selecting inoculum.
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.
