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!

I did a demo on these and they were easy to use and the people really seemed to like them.

Maybe I'm just having a particularly dense moment... but, what do the blocks do? (and the. rebar, for that matter...)

Your boards are the side walls of the bed and the block are your connectors. Slip the boards into the slots to form what ever type bed you want. The rebar goes into the hole in the middle and into the ground to keep the block from moving.

You position them to the size you want and just slot 2 x 6 cedar boards into them . You pound the rebar into the holes in the middle to hold them in position and so you can stack them on top of each other.

Oh, geez... thanks, Jay and Bob! for some reason I was thinking these were "raised off the ground beds" -- like big planters raised up at waist level. Not sure why my mind was going in that direction...
