Well I wasn't really going for a forest garden. I ought to sig this, but I live in a neighborhood, so I'm not sure how full throttle I can go with a food forest. I'll get that book when I can; I've got Introduction to Permaculture
, which I haven't read. my life is full of distractions.
One site I ran across said a windbreak will protect 10-15x the height of the windbreak; is that accurate? Would bamboo make a good windbreak? The most sensible place to plant a windbreak in my yard would be 170' south of the garden/fruit trees. And I correct that something 20' tall would be sufficient?
