    concrete blocks

I used 16x8x4 inch concrete blocks for one of my garden beds.  I set them with a 4×16 inch side down so they are 8 inches high..  They cost about $1 per foot of bed edge and are quick to set up, but can't make a bed deeper than 8 inches unless you lay them like bricks with mortar or hammer in rebar on the outside to prevent toppling or stack them flat in which case the cost quadruples for a 16 inch high bed.  They work great for 8 inch height.
