Tree Staple Stabilizer

No lines to trip on—easy to mow!

Patented below grade stabilizing system for trees and shrubs. Reduces liability due to no above ground obstructions. Fast, consistent and installs in seconds. Below grade system is safer, faster to install, with no removal costs and is totally unseen after planting.

The Tree Staple is constructed of uncoated, cold-rolled, plain carbon steel that will rust and dissipate in the soil over time so there is nothing to remove later. This system is the best choice for aesthetics and simplicity. Provides stability but allows for natural trunk movement stimulating root growth. Don't let unsightly wires and stakes detract attention away from your landscaping job, use Tree Anchor Staples instead. Use two staples per tree for standard applications. Priced and sold individually.

QUESTION: How is the Tree Staple installed?
ANSWER: The product comes with more detailed instructions, but the basics are as follows; position each Staple on opposite sides on the rootball, with the shorter prong over the rootball, (halfway between the trunk and the ball's outer edge), and the longer prong just outside the edge of the rootball. Use a sledge to drive staple down untill the Staple crossbar is approx two inches below the surface of the rootball. Cut back burlap and fill as normal.

QUESTION: How do tree staple stabilizers work?
ANSWER: Tree Staple stabilizers hold a treeΓs root ball firmly in place. The longest prong provides vertical support and serves as an anchor below the root ball. This minimizes shifting in the soil. The cross member stretches across a portion of the root ball, applying downward pressure. This allows proper movement of the tree in the wind, without allowing the root ball to move. The shortest prong restricts twisting, further reducing ball movement and firmly locking the root ball in place.

QUESTION: How many stabilizers do I use?
ANSWER: Two are all you need for most plantings. Occasionally, conditions such as loose or sandy soil, extreme winds, or tree size may require a third stabilizer. Instructions for installation are included in each box.

QUESTION: What size stabilizers should be used?
ANSWER: The best holding power results when Tree Staple stabilizers extend a minimum of 12" below the depth of the root ball. We recommend that in loose or sandy soil conditions, or in extreme wind conditions, that you consider increasing size or adding a third stabilizer.

QUESTION: How long does it take to install tree staple stabilizers?
ANSWER: It takes 1 person approximately 1 minute to install 2 Tree Staple stabilizers.

QUESTION: Do I need any special tools?
ANSWER: No. All you need is a sledgehammer. No other tools are required. Tree Staple, Inc. highly recommends the use of hand and eye protection.

QUESTION: What are tree staple stabilizers made of?
ANSWER: Uncoated, plain carbon steel.

QUESTION: Will tree stabilizers damage the roots?
ANSWER: No. In six years of controlled use, there has been no indication of damage caused from the spike or cross member entering the root ball. Any piercing will, at worst, cause the roots to grow around the impediment.

QUESTION: Do I still need to use guy wires in areas with high winds?
ANSWER: A tree that has been properly planted with Tree Staple stabilizers will hold as well as or better than other methods. Guy wire installations introduce an unnatural stress at the point where they attach to the tree. Sometimes strong winds will break the tree at this point. With the Tree StapleΓ system, this does not happen.

QUESTION: Is below-grade stabilizing actually good for trees?
ANSWER: Tree StapleΓ below-grade stabilizers eliminate potential girdling, damage to the bark and the abnormal stress normally created by traditional, guy wire methods. They also allow the tree to move in the wind, the way nature intended. According to Purdue University, "The result is a better balance Γbetween canopy size, trunk caliper, and the root system."

QUESTION: Do you have to adjust or remove tree staple stabilizers?
ANSWER: Tree Staple landscape products eliminate the need for subsequent maintenance or retrieval, saving the labor and disposal costs associated with those activities. Use the cost saving calculator at the Tree Staple website: to see how much you will save.

QUESTION: Are tree staple stabilizers reusable?
ANSWER: Yes. However, they are designed to be left behind. The labor involved to retrieve the devices once installed may exceed the cost of new products. And of course, you would have to find them first.
