Drainage and aeration device for plant containers

Abstract

A drain shield for a plant container prevents compaction of soil, maintain drainage and provide for aeration of the roots of the plant. The drain shield comprises a unitary molded disk with a plurality of cube-like supports which are circumferentially spaced near the perimeter of the disk. The supports are positioned inward from the outer edge of the disk creating an eave around the perimeter of the disk that overhangs the supports. When the disk is placed on the bottom of a plant container, the supports form a series of uniform passages that lead to an unobstructed inner space under the disk. The side walls of the supports, as they relate to each other and to the center of the disk, are tapered in such a way that the passages between adjacent supports becomes larger toward the center of the disk. The underside of the disk, and to the inward side of the supports, is concave, forming a dome.
