Claim:
A barrier, for a plant pot with sloping inner walls, placed within the plant pot and against the inner walls of the plant pot, comprising: a disk made of a single piece construction and having a substantially circular outer perimeter; said disk defining a first plurality of circular apertures distributed substantially throughout the disk; said disk having a generally convex upper surface, and a generally concave lower surface, at least one of the first plurality of apertures being centrally disposed in said disk, and extending from said upper surface through said disk to said lower surface; said substantially circular outer perimeter defining a flange extending in the direction of said convex upper surface, said flange defining a substantially concave region surrounding said convex upper surface, and a second plurality of circular apertures being uniformly distributed substantially in a lowermost portion of the concave region surrounding the convex upper surface; wherein said disk being disposed such that a layer of soil is supported on said convex upper surface of said disk, and defines an enclosed air space below the generally concave lower surface, said first and second plurality of apertures allowing water to percolate through the layer of soil and into the enclosed air space, and simultaneously maintaining the layer of soil above said disk; whereby said flange frictionally engaging the inner walls of the plant pot, and is supported within the plant pot entirely by the frictional engagement.
