Just wanted to give a heads up that I ran across this system for raised beds at my local Home Depot (I'm not affiliated or anything) I just thought it was a really neat idea.
So basically, these blocks, some rebar to keep them in place and some 2" x 6"s is all you need. Here's the 10 I picked up (BTW less than $2.50 each) They also stack so you can do multiple levels.
Now let's get creative!
