ABSTRACT:
A device for assisting the growth of a plant by providing shelter and physical support therefor is taught in the preferred embodiment of a modular construction including a tubular section, a cover, and a collar. The collar provides a gradually curving continuous support to the upper growth portion of the plant for helping to reduce breakage of the plant from bending due to the weight of the plant. In the preferred embodiment, the collar includes arcuate sections of varying radii, with the first arcuate section connected tangentially to the tubular section, with the second arcuate section extending radially outwardly and continuously from the first arcuate section, and with the third arcuate section connected to and extending radially outwardly, downwardly, and continuously from the second arcuate section. An outer rim extends from the third arcuate section for reinforcing the collar. The collar is removably connected to the tubular section allowing the separate fabrication of the collar and the tubular section. The cover provides a weather barrier for the plant and is removably received either in the tubular section or in the collar.
