Hardiness Zone: 6a
By Heidi from PA
I have used 8x8x16 cinder blocks as the edging for my raised beds. I do "nail" them down with rebar so they don't shift. If you get a sale, they aren't too expensive, or check around colleges when school gets out and pick 'em up for free when the students leave them behind.
Heidi, you could use old wooden pallets. I know at work, we gets lots of spare ones. We give them away to people for putting firewood on, temporary flooring, broken ones are ideal for firewood etc. Most businesses are pleased to get rid of them. They make good compost heap frames. Most are made of untreated wood, which is ideal. No chemicals leaching into plants. Best of all, free. I have heard of freecyle that may be another option. Many lumber yards also have offcuts and they will sometimes give them away or even packing crates are good, if companies import heavy items. Just a few ideas. brentnz
