CONCRETE BLOCKS: They now make blocks that are 1/2 the size & weight of regular blocks. I used these to make my raised garden. Be sure to put the blocks close together so no soil can run out.
I TILLED the area first, after adding peat moss (anything organic is fine). I then dug down a couple of inches where my blocks were laid and threw this dirt in the middle of each bed. I have placed black plastic & old carpet between the 4'x12' beds, to have a dry area to walk on.
