ABSTRACT:
A watering device for plants includes a plant container which is balanced on a vertical moving rod by a spring and a water reservoir tank is operatively associated with the plant container so that as the plant container becomes lighter due to a loss of water, the spring member disposed at the opposite end of the vertical moving rod from the plant container actuates a valve in the water reservoir tank and transfers water from the water reservoir tank to the plant container until a balance is again achieved, and when the balance is reached, the valve in the water tank is again closed.
