Butcher block cedar sides and lifetime aluminum corners make our Rolling U-Garden handsome and durable; heavy-duty casters make it mobile on your deck or patio. Roll it into the sun, or out of the way to make room for guests. The 2' x 4' planter box is 14" deep — plenty deep for your largest vegetable or flower plants. It accommodates three of our Tomato Cages with room to spare! The U-Garden Watering System helps provide plants with a steady supply of moisture, and means you'll need to water your plants less often. In our test gardens we watered 60% less often, compared to a U-Garden without the watering system. The 5-gallon reservoir helps plants get a steady supply of water through contact with the soil, as well as through evaporation. When it’s time to fill the reservoir, attach your garden hose and in just a few minutes the soaker hose fills the reservoir. The reservoir also captures and stores rainwater, while allowing excess water to drain. Install the watering system prior to planting your U-Garden. Includes a liner to keep soil contained while letting excess water drain.
