The Century Universal Tree Ties are used for staking and supporting newly planted trees that require support to prevent breakage of limbs from strong winds. Our Tree Ties strengthen the trunk by allowing it to move slightly from side to side, enabling the trunk to build reaction wood and strengthen with time. Our tree ties also expand with the growth of the tree and will not girdle, scar or damage the bark on the trunk and will continue to work efficiently until the tree requires no additional support. Our Tree Ties are a green product that enables ease of use and maximum durability while preventing damage to the tree.
