Mine are 80% 10' tall looks good 85% might work for southern states hotter summers? Northern states maybe 75%.? Not sure
175' x 175' beds are 6' wide with 2' walk path. I chose a post every 16' in every direction most cloth comes in 6, 8, 12 are very common, I also use hybrid poplar trees and hybrid willows in between so in a few years no need for cloth. Dug paths first pulled topsoil in beds tilled it up and ready set go. I have access to a ton of leaves each fall chopped up adding leaves will harden the soil causing the roots to slow there growth and become a little tighter and look more wild in the future is the plan good luck.
