24″ Wonder Tree Ties Wire Length: 72″. The Wonder Tree Tie was the first really significant breakthrough in tree ties since they first were used. Wonder Tie have a patented spring action that allows the tree to grow naturally without restriction that may kill or permanently damage a tree. Trees are allowed to sway with the breeze and then retract to their original position with normal pressure on the tree stake. This freedom of growth allows for a much stronger root system.
