Great idea from a backyard vegetable garden. These concrete “stones” are easy to make and work beautifully at terracing a slope.
Here is how the gardener did it: She stacked bags of concrete in a row, then wet down the bags for a week or until the concrete hardened. Once hard, she tore off the paper wrapping.
Then she added another row on top of the first, wetting the second row of concrete bags, waiting for the concrete to harden and then removed the paper – and so on until she had her vegetables beds at a height that worked for her.
