Plant support consisting of a base and a spiral, fitted rotatably thereon and extending vertically. This spiral is made for accommodating therein the main stem of a plant, such as pepper, cucumber, aubergine or tomato. Branches of the plant extend outwards to beyond the spiral. In the spiral is a stationary post. If the plant has reached the top of the spiral, the spiral is rotated with respect to the base such that the plant shifts downwards without rotating. The plant can subsequently continue to grow upwards again. A number of plant supports of this type can be combined with a common drive.
