Build a Raised Bed for your Garden
Planter boxes are a great way to add garden elements where you might not have the best of soil conditions. wooden boxes are attractive, but you're limited in shape, wood can rot, and they take some time to build. You can build a concrete planter box, like the ones shown on Yard Crashers, and make different sizes. The blocks come in a lot of different colors, too and they are easy to move around.
