If you've ever had to build your own rock wall border or edging, then you understand how difficult a task it is. Don't struggle with heavy, cumbersome, expensive, decorative bricks. With the Garden Wizard Landscape Border, simply connect large sections together in seconds without the physical burden. Each wall only weighs a few pounds and is easily connected with the next by using the included stakes (stakes can work on flat surfaces or be driven into the ground by sliding a piece of metal or rebar into the sleeve). Use the rock walls to border gardens or link them together to make a customized raised garden bed with self-watering walls. These walls hold and distribute up to 5 gallons of water with the included soaker hoses and clamps. Just pour water directly into the wall and the slow-drip, wicking action of the hoses does the rest. Made of polyethylene in the USA using FDA approved materials.
