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.
Thank you you been helpful. I live in PA and don't have property of my own that has any maples or hard woods on. I only own half acre. I would like to do a 6'×30' raised bed, i am thinking maybe enough room for 500 seeds/roots.
Find a machine shop local and get you some angle iron drill a hole in top 10' should be good have them weld a spade on the bottle drive them in 2' and there ya go your cloth should be longer on each side to angle out for keeping shade on the edges, fiery red maple grow fast as does yellow hybrid poplar. Cloth can be found on ebay unless the host sells it 75% should work for you the cloth without he grommets are cheaper... You can buy clips for them also on ebay...Have fun growing
