The present invention relates to protecting house plants from dying as a result of dehydration, when they are neglected, or when the householder is on vacation, for example. The invention involves an annular flange which is sealed to the inside bottom of a flower pot, and also includes a short upstanding conduit or pipe which is sealed to the flange around the flower pot drain hole. The flange may be of porous plastic for ease in cementing to the bottom of the flower pot, and the upstanding conduit may be either integral with and formed of the same material as the flange, or may be a separate short length of plastic tubing. In practice, when the plant is watered, a certain amount of water is trapped between the conduit and the sidewalls of the flower pot toward the bottom of the pot so that the entire soil within the pot stays moist for prolonged periods of time, thus providing good growing conditions for the plant.
