ABSTRACT:
An irrigation spray stake for plants grown in pots utilizes an elongated stake member having an upper extremity and a lower extremity adapted to be inserted into the soil, with a spray head adjacent the upper extremity of the stake member, with an arrow or similar feature along the stake member between the upper and lower extremities to indicate the predetermined spraying direction of the spray head. The arrow or similar feature may be formed as a plate which rests against the surface of the soil, with the back edge of the plate resting against the inner surface of the nursery pot into which the stake is extended.
