I sure hope you all don't think I do is wonder. But if any of you have tried this tell me. Lets say you have a bunch of five gallon bucket tops and are not using them for anything. Why can't you drill a 2 or three inch hole in the middle of the top with a bunch of little pin hole around it to let water through. Prepare you ground then put the bucket top down over a tomato,pepper or some other plant to keep the grass from taking over? I am sure this has been done before because everything I think up has. Wondering how it would work? Am going to find out if I live long enough.
