Abstract:

A first outer container is formed with a side wall and a bottom wall. The bottom of the first container has a support structure or raised area to define a water reservoir in the bottom of the container. An overflow drain is provided in the container and preferably in the raised area to limit the depth of the water reservoir. A second inner container including a drain hole and having a live plant is placed in the first container at or above the water level in the first container. The water in the first container has a depth to inhibit excessive root growth from the drain hole of the second container. Roots which grow through the drain of the second inner container contact the standing water in the reservoir and die and rot at the point where the roots contact the water to limit growth in the first container. The water in the first container is particularly effective in controlling root growth from the inner container through the drain holes in the first outer container.
