Abstract: A plant support system that is self-adjusting in height to accommodate growth of a plant, and a method of using such a system. The system includes a pole assembly having a base and first and second pole sections. The base is sized to be received in a container, the first pole section is coupled to the base of the pole assembly, and the second pole section is coupled to the first pole section so as to enable the second pole section to longitudinally extend and retract relative to the first pole section while remaining coupled to the first pole section. Features are disposed on at least the second pole section for releasably securing portions of a plant longitudinally extending alongside the pole assembly. The container is preferably supported by a turntable to rotate about its axis of symmetry.
