The hubby can't get the cement out of the garden. It is about 3'x3' and at least 8" deep (we never found the bottom).
Therefor, we're srrounding the whole thing with railroad ties and filling it in with dirt.
Is 8 inches of soil enough for plants to grow over that cement? There is about a 3x4 inch hole in the center that's all dirt.
I'm thinking I'll be ok as long as I plant peas and beans and more shallow rooted things there.
