  • Patent number: 11785904
    Abstract: Disclosed is a self-watering insert for placement within a plant container, the insert comprising a one-piece self-supporting structure having an open bottom end, a closed top end, downwardly-sloping sidewalls, an open or closed interfacing structure that facilitates a secure seal of the insert against an interior wall of the plant container, an open collar on the top to allow temporary insertion of a pipe or water-discharging mechanism into the watering insert, a plurality of holes and/or screen/fabric material permanently attached to the surface of the top end, allowing water and air to pass through the surface. A lower flange extends circumferentially around the bottom end of the water insert, thereby creating a shelf upon which growing medium rests; the flange further featuring downward protruding fins spaced so as to provide channels through which water passes from underneath the interior of the watering insert to its exterior.
