Put the cardboard on top of the grass? I’m not sure if I can get hubby to till it up, he’s kind of a whiner. He will only do his projects first.
Although part of the deal for him getting a big tractor is that he could dig holes for trees and he got a rototill attachment. Well, There’s no point having it if he’s not going to use it!
Yes. The cardboard goes on TOP of the grass, INSIDE of the raised bed.
Hire it out if need be. Send the bill to Hubby, LOL!
