DuPont™ UnderAnchor® Tree Stabilization System
For best results, the tree’s root ball must be firmly intact. Dig a hole 2–3 times wider than the root ball diameter and slightly shallower than the root ball height.
Center the root ball in the hole, making sure that the root ball crown is ½ to 1 inch above the surrounding soil. If necessary, use a small amount of soil to secure the tree in an upright position.
Once the tree is adequately positioned, place the DuPont™ UnderAnchor® fabric around the base of the tree trunk by opening the slit and centering on top of the root ball.
Use the small (8") cable tie to loosely join the looped tabs located halfway along the open slit.
Insert wooden stakes in the soil at the bottom of the hole, adjacent to the root ball and aligned with the tabs at the corners of the DuPont™ UnderAnchor® fabric. Drive stakes firmly into the soil, leaving access to the hole in the top of the stakes.
Run a large cable tie through each DuPont™ UnderAnchor® tab and through the hole in each corresponding stake. (At the fabric slit, run cable tie through the two adjacent loops.) Loosely secure each tie. DO NOT TIGHTEN until all cable ties are in place.
Once all cable ties are loosely secured, begin to tighten while keeping the DuPont™ UnderAnchor® fabric centered on top of the root ball. This is best accomplished by slowly tightening cable ties opposite each other while working your way around the root ball. Check all cable ties to assure taut and uniform anchoring.
Backfill soil into the hole. Tamp down. Water as necessary.
DuPont™ UnderAnchor® is an attractive and reliable solution, stabilizing newly planted trees underground.
