A seedling growth enhancing device is disclosed which takes the form of an elongated tubular shell formed from three shell segments each having a radius of curvatures less than the effective radius of curvature of the tubular shell. The device is thermoformed from thermoplastic and includes a flexible hinge joining two common edges of the three shell segments. The third common edges are formed with male and female snapping members enabling the device to be formed around a seedling and snapped into place.
