ABSTRACT:
A device for mechanically checking the growth of noxious weeds within the growing containers of potted plants is shown. The device includes a mat of porous construction adapted to fit within the open top of a pot and engage a side wall thereof for inhibiting weed growth by shading the pot interior from light. A retainer, for positioning atop the mat, frictionally engages a side wall of the pot and retains the mat securely within the open top thereof. The pot may be provided with an overhanging and inwardly directed lip proximate the top of its side wall for engaging the retainer and locking such in place. In an alternative embodiment of the device, the retainer is formed as a ring, having an inverted U-shaped cross section, integrally joined to the outer edge of the mat for frictionally securing the mat to the pot. The device may also be provided with one or more chemical treatments such as herbicides, insecticides, fungicides, and fertilizers for promoting the growth of specified plant materials.
