I'm building out my community garden concept this year, and was wondering how I can use square food gardening to grow mushrooms in the walking paths, and vegetables on the sides with none of the same plant roots touching unless they're on the same plant while incorporating the layering technique (like a forest).
I plan to hugel mound where the plants grow to and in the paths put about 2 inches of manure, then 3-4 inches of wood chips, then some 2-3 inches of hay, then about 1 inch of wood chips above that. with a holy watering pipe on one end on the lower layer of wood chips to aid in water distribution (think of the Geoff Lawton Jordan project with rotational weekly produce aisle).
