I live in Indianapolis, in zone 5. I love the idea of sheet composting and I've been doing it in my own backyard for years. I would have to teach people in the area what it is, how it works and that it doesn't attract vermin, which some will have concerns about. Are there any really good reference books about wild edibles that has photos that I might be able to share with my neighbors. I only know a few edible weeds and the neighbors are amazed when I point out that they already have food growing in their yards.
