Abstract: A self-watering flowerpot has two chambers: an upper one for accommodating soil and a plant and a lower one for accommodating water. The upper chamber has a downwardly protruding tubular neck and threading around a lower outside periphery thereof. The lower chamber has an upwardly protruding tubular drain and threading around an upper inside periphery thereof. A tubular conduit element made of porous material is positioned between an outside periphery of the drain and inside periphery of the neck when the upper and lower chambers are threaded together. The two chambers are rotatable relative to each other so as to control the flow of water from the lower chamber to the upper chamber via the conduit element. An inlet pipe allows water to be filled into the lower chamber.
