Abstract: A plant cage for placement about a plant for assisting in plant growth. At least three vertical rods are arranged relative to one another to define a three-dimensional area into which the plant is locatable. One or more ring members have a circular shape and are formed from two separate components that are pivotal relative to one another to provide an open position for the cage. Two fasteners are connectable to each of the two ring ends. Grommets are disposed on the rods and connect to the ring member, and are positioned at a vertical height along the rods.
