Grower's Edge? Colored Deluxe Steel Stakes are ideal for all your heavy-duty plant supporting needs. The spurs on the stake keep the tie string or tape from slipping down, keeping your vines where you want them. The steel core is coated with plastic to make them weather and rust proof. They won't split, deteriorate or rot like bamboo stakes can. These stakes are great for both indoor and outdoor use. Comes in 4 different colors: the original green, and now blue, red or yellow for plant type identification and easy spotting of the stake.
