ABSTRACT:
A device for automatically watering potted type plants has a shallow reservoir base/tray capable of holding water and also capable of supporting at least one previously potted plant and also capable of supporting an inverted container (such as a typical screw top jar turned upside down) for containing additional water (and/or other plant nutrients). A specially adapted support base is used to keep the bottom of the inverted container (where the opening is located) slightly above the bottom of the base/tray. The base/tray can have ribs or rails to keep the potted plant raised slightly above the lowest part of the tray (but lower than the opening in the inverted container). The water container has a detachable lid with a hole. The detachable lid is attached to the water filled container (not yet inverted) and the lid and container are fixed to the base/tray while the hole is covered by the plant owner's finger creating a partial vacuum in the water container such that water will only flow from the water container when the water level in the tray/base drops below the level of the inverted container opening.
