Anyone here use cement blocks for raised beds?
I am trying to construct a raised vegetable bed with cement blocks. I layed them out butted against each other and leveled them, filled this 12x4 area with dirt. Now I am seeing that the blocks are unstable to work around though. When using a pitchfork in the bed, I have to be careful not to knock into them or it knocks them out of kilter. Standing or sitting on them seems unstable. I don't want to keep resetting them either.
I haven't filled the holes with anything yet as I have been told I can plant the holes with plants, but I can't see how you can access what is in the bed and work in it if you have plants all around the edge.
Someone suggested rebar the corners for more stability and I plan on it, but I still don't see how that will stabilize all the blocks the way I want them.
What am I doing wrong?
