  • Patent number: 9185853
    Abstract: A double-walled nested plant pot assembly having a base pot and an insert pot, the latter removably inserted into the base pot. The base pot has a bottom and tapering sides, an open top, a drain hole in the bottom, and legs on the bottom for elevating the base pot above a surface. Clearance holes are provided for plumbing to be disposed under the base pot bottom. A pipe fitting is disposed in the drain hole for connection with a drain line. Stand offs are formed in the base pot for supporting the insert pot. The shape of the insert pot conforms to the base pot with slightly smaller dimensions and includes a basin portion with a plurality of drain slots. When placed on the stand offs, the spaces between the basin portion, the insert bottom, and the interior sides and bottom of the base pot provide a volume through which water may drain from the insert pot into the base pot and through the base pot drain.

    Abstract: An improved drain hole cover for use in all types of planting containers is described. A preferred embodiment of the drain hole cover comprises a single generally discoid layer of lofted synthetic nonwoven material with a pressure-sensitive adhesive applied to one side. Generally, the adhesive can be applied to a periphery of the one side of the drain hole cover in a pattern so as to leave a central portion uncoated by the adhesive. The drain hole cover can be disposed, adhesive side down, on an inner surface of a planting container concentric to a drainage hole of the planting container. In use, the drain hole cover allows water to drain out of the container and prevents the egress of soil through the drainage hole.

  • Publication number: 20020174599
    Abstract: An aerating base plate designed for placement in the bottom of a conventional plant receptacle, such as a flowerpot. The plate has a sidewall that extends downwardly from the perimeter of a convex top. The top includes a number of perforations that function to enable water and air to flow into, or out of, an interior area of the plate. The plate's sidewall features a number of openings that also enable water and air to flow into, or out of, the plate's interior area. The sidewall's openings are sufficiently small so that they substantially prevent any flow of soil into the plate's interior area.
