If you're trying to decide what to do with all that extra space in your yard, you might want to consider starting a garden plot. Still, if you don't have the time or the money to build professional garden boxes, the project might go off the rails, and your flowers might be doomed from the start. But, if you have some extra cinder blocks lying around, you can create easy, gorgeous flower beds in the blink of an eye.
These DIY planter boxes can also be used to grow vegetables or herbs. Just make sure you place a protective layer of tarp below your planting soil.
