An innovative design, the Garden Wizard Raised Bed Garden uses four interlocking 50" wall sections to enclose a 4'x4'x10" space and holds water to provide your plants with water when they need it. When you fill one wall with water, it transfers to each of the other walls while simultaneously watering the garden through the unique soaker hose system connected to each wall. Using a slow-drip, wicking action the hoses only deliver water to the soil as needed. So, you can be assured that plants will stay watered, but not over-watered. Easy to assemble in no more than 5 minutes from start to finish. Simply layout your setup location, connect the wall sections with the pins, and attach the included soaker hoses (optional). Made using FDA approved polyethylene materials.
