  • Wick insertion device for a plant pot
    Patent number: 4932159
    Abstract: A self-locking wick insertion device for a pot to permit bottom watering of a potted plant by capillary action, the device including a base, a generally centrally positioned upwardly extending stem, and circumferentially spaced, radially extending ribs formed on the stem. A groove is formed in the top of the stem for snugly receiving the wick, with a slot being formed in the base through which the wick can extend into the water supply. The ribs are inserted into an opening in the bottom of the pot, with the radial dimension of the ribs being such that the ribs are slightly radially compressed during such insertion to provide firm frictional engagement of the ribs with the wall defining the opening. The wick is maintained within the growing media for the plant, and water from the water supply can be transmitted by capillary action through the wick to the growing media.
