EASY DIY concrete planter box All you need are a few - pavers, landscape-block adhesive, and a little time. Wait 24 hours for everything to cure and you're ready to move your new planters into place and fill them with dirt and greenery.
interesting idea: plant box and belts . Hook together several belts to be large enough to go around if using real leather belts (from thrift store) . these "belts" look more like strap webbing and could be DIY made to size.
