Red Tomato Automator Tray, All-Purpose Feeder, Waterer, Weeder, Includes 3 Trays

The tray itself is an all-purpose feeder, waterer, and weeder in. Simply fit the tray around the young plant, pushing the 4 corner stakes securely into the soil. The red color stimulates growth in young tomato plants by giving them the signal that they are overcrowded; they begin to gain height and foliage at a faster rate when red is used around the plants.
