Abstract
Abstract A device formed as an integral plastic piece having an inner tubular portion to surround the stalk of the tomato plant and an outer support portion which defines a circumferential trough surrounding the inner tubular portion. The inner tubular portion is placed around the stalk of the tomato plant, with the lower edge of the tubular portion being implanted into the ground. The upper growth portion (i.e., vines) of the tomato plant and the tomatoes are conveniently retained in the trough.
