Abstract
Abstract A device for automatically supplying water to house plants over a prolonged period of time including a body for the storage of water and an elongated neck with a small hole in its side attached to the body. When inverted the neck is stuck into the potting soil of a house plant so the body rests on the soil, water slowly seeps out into the soil. When in an upright position with holes made in the body portion, and the device is hung by appropriate means, it may also serve as a rooting device when plant cuttings are inserted into the water in the body through the formed holes.
