Love the height of these raised flower beds. Easy to put together. I filled the bottom layer with old rotted wood, layered with twigs, then horse manure and topped off with potting soil. Gave four stars because the support bars that go in the middle are flimsy aluminum type material and do no good. They bend when you try to mount them. First year using them. Would like two more. Have planted 2 with broccoli, Brussel Sprouts, cabbage, lettuce, radish and onions.
