Using concrete blocks to build beds?
I'm going to be building my raised garden beds soon. After looking at different types of lumber and stuff, I thought of using concrete blocks. They're 8"x8"x16", so I should only need 14 of them per bed, since the beds would only have to be 1 block tall. Has anyone else used concrete blocks? I know they're not very pretty, but they're inexpensive (which is important right now), and I won't have to worry about them rotting. If you've used them (or know someone who has), I'd appreciate any information you can give me. Thanks!
