O.K. guys and gals. I want to make some raised beds this Spring. 20 feet long, 50"-54" wide inside, 24" tall. It freezes up here, and I only want to make them once, not re-do them in 20 years. I want to make 3 of them. That wide because I can drive my garden tractor with the tiller on the back in and out of them.
I was thinking pour a 9"x9" footing in the ground, using the ground for a form. Use 3 courses of 8"x16" block. rebar in the footing, rebar coming up from the footing, filling the lowest course and part of the 2nd course and using a tie to help hold the wall from "pooching" out during the freeze/thaw cycles we have here.
I also looked into using PT wood rated for ground contact. Then I saw PT wood prices.
Thoughts and suggestions?
