ABSTRACT:
A two part plant container includes an outer tub part having a series of step indentations around its perimeter forming horizontal rest surfaces within the outer part which are located above a lower region forming a water reservoir space. The inner part has a bottom wall areas resting on the surfaces with the inner part nested within an upper region of the outer part. A drain hole is formed through a depressed area in one of the rest surface to set the maximum water level in the reservoir which is just below lower areas of the inner part bottom wall set at the same level as the drain hole. This insures that the soil in the inner part is never wet by the water in the reservoir to prevent wicking and waterlogging of the soil while leaving only a very short gap for the roots of a plant to grow across to reach the water. Handhold features are formed into the perimeter wall of the inner part allowing easy lift out. Ribs are formed into the inner part bottom wall to stiffen the same.
