ABSTRACT:
A plant watering system for flower pots, plant boxes or open fields which uses watering cylinders located adjacent to the plant roots with the watering cylinders connected to a water supply unit through a closed pipeline system with the water supply unit maintaining a constant level of irrigation water. Moistening of the soil in the region of the watering cylinders permits the inherent suction intensity of the soil to suck water from the reservoir to the plant root when the available water in the soil is low and to not suck water from the reservoir when there is adequate moisture in the soil. The watering cylinders having means to prevent growth of roots therein while permitting water to be discharged to the surrounding soil.
