ABSTRACT:
A device for rotating a hanging plant to keep it from growing lopsided. The device has counteracting coaxial tension springs of opposite hand that rotate the plant first in one direction when the plant is watered and then in the opposite direction as the plant goes from wet to dry. A weight change of 10-20% is sufficient to rotate the plant at least 1/2 turn. An indicator is responsive to changes in the length of the springs as the plant dries out and as the springs are axially unloaded.
