I have been mulching with native Sumac. Is it allelopathic? Also I wonder what the half life of the allelopathic compounds are. Are these compounds water soluble or do they sit on top?
Diversified Food forest maker . Fill every niche and you'll have less weeds (the weeds are the crop too). Fruit, greens, wild harvest, and nuts as staple. Food processing and preservation are key to self self-sufficiency. Never eat a plant without posetive identification and/or consulting an expert.
