  • Publication number: 20090223127
    Abstract: A plant watering apparatus has a container (1) filled with a suitable growth medium (2) and is attached to a foliage support plate (3) by a bar (4) operatively coupled with a spring loaded water control valve (6). Decreasing weight of the container opens the valve to feed water to container. The plate (3) is supported by a wall or ceiling bracket (10) by means of suspension rods (11). Plants (12) are added through holes (14) in the plate (3) and the plant root ball (13) is embedded within the medium (2) with the plant foliage overlying the plate (3). When sufficient water is present in the container 1 the spring loaded valve 6 will be closed. As the medium (2) in the container dries out the weight will reduce and the valve will commence opening. The foliage is supported by the plate (3) and foliage growth will not significantly add to the weight of the container and thus will not affect the operating point of the valve over extended periods of time.
