Abstract: A moisture gauge for a hanging potted plant, which comprises a generally U-shaped spring element comprising a spring coil and a pair of approximately parallel arms extending from said spring coil shaped to provide notches opposite one-another at spaced intervals along the facing edges of the two arms, one of said arms terminating in an indicator, the other arm having a cross-wise extension providing a moisture indicating scale. Adjoining segments of the pendant support by which the hanging potted plant is supported are connected respectively to oppositely notched portions of the two arms selected with reference to the weight of the potted plant when fully watered, so that the indicator will be extended as accurately as possible to the fully watered position.
