Grower's Edge? 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 green plastic to make them weather- and rust-resistant. They won't split, deteriorate or rot like bamboo stakes can. These stakes are great for both indoor and outdoor use. 6 ft and 8 ft stakes cannot be shipped UPS Ground.
