Here is a perfect way to tame a potted vine. Just unfold this compact spiral and attach each end to a 36" (or shorter) bamboo or hollow metal stake. Push one end of the stake into the soil and it creates a spiral on which to train your plant. Inexpensive, compact and useful.
Made in England from galvanized steel. Provides 9' of growth along the spiral, but it is all kept in an area only 3' in height.
