Concrete blocks are a convenient, affordable option for raised garden beds. They are more durable than wood and cheaper than metal alternatives.
Unlike old-fashioned cinder blocks, which contained coal ash, concrete blocks are made of a stone or sand aggregate and are thus safe for gardening.

One of the main benefits of gardening with concrete blocks is your ability to customize the dimensions of your garden bed without having to do much of anything beyond arranging and rearranging your concrete blocks.
No saws or power drills. No tie plates or wood joiners or screws of any kind. Just place your blocks, make sure they’re level, fill them with soil, and get to work!
Depending on annual weather conditions in your area, your concrete blocks could last anywhere from 50 to 100 years before they crumble.
Compared to the 10 or so years that it takes for wooden beds to decompose, concrete beds are an incredibly affordable option for those interested in creating raised garden beds that stand the test of time.
