ABSTRACT:
A device for watering plants adapted to be installed within the soil. It includes a perforated sleeve within which is accommodated a perforated tubular insert. The sets of holes in the insert and sleeve are respectively located so as to be selectively registerable with each other. When these sets of holes are not in registration, the sleeve holes are closed to prevent contaminants from entering and blocking the perforations. This is particularly advantageous when the device is being inserted into the soil. Movement of the insert relative to the sleeve after the device is implanted can be used to bring the perforations into registration with each other to allow the flow of water outward into the soil to nourish the plant. A spiral ridge is provided on the outer periphery of the sleeve to facilitate insertion of the device into the soil by rotation of the sleeve. Also, the top of the device is attachable to a container having a selectively closable opening in its bottom. The container might be used to store a supply of water. A timer is provided to periodically communicate the container with a passage within the device via this opening. Automatic watering of the plant can thus take place.
