The French inventor succeeded in developing a cone-shaped skirt that grows well with plants, covering the roots of the plants underground and connecting them with a cylindrical collar that protrudes into the stem of the ground to form a complete Tapered skirt device. On the inner surface of the skirt and collar there is a series of drains extending over the entire wall of the device to deliver water and air to the roots of the plant.
