ABSTRACT:
A height adjustable plant support device for supporting and confining vegetables, flowers and other plants therein is disclosed. The device includes a pair of generally circular end rings and a coil constructed of flexible material such as plastic having constant diameter throughout its length connected between said end rings. In a first embodiment, a pair of spaced apart stakes are used to support the rings while in a second embodiment, the rings are supported by a single stake projecting through the middle of the rings and coil. In the first example, a first pair of clamps are slidably connected to the lower end portions of the stakes and contain hooks which open downwardly to confine a lower one of the end rings therein at or near ground level while a second pair of clamps are slidably connected to the upper end portions of the stakes and contain hooks which open upwardly to support an upper one of said end rings therein at a desired position spaced above the lower end ring. In the second example, a pair of elongated members containing hollow collars on their mid-portions are slidably disposed over the single stake, the lower one of which contains hooks on the ends thereof which open downwardly to confine the lower end ring at or near ground level and the upper one of which contains hooks on the ends thereof which open upwardly to support the upper end ring at a desired height above the ground.
