Abstract: A tree tie engageable about the trunk of a tree and fixed to a supporting post set adjacent the tree. The tree tie is such that it will yield about and freely permit the trunk of its related tree to grow or increase in size and is such that it will yield, buffer and absorb shock-like forces imparted into it upon rapid movement of the tree relative to the post. The tree tie comprises a collar established of a length of rubber or plastic hose engaged about its related tree trunk, a pair of elongate cable or wire lines extending from within the opposite ends of the collar to the support post with which they are secured by anchoring means and helical spring means within and carried by the collar and connected with the ends of the lines within the collar. The spring means operate to normally yieldingly impart tension on the lines whereby the tree is yieldingly prevented from bending and/or tipping in a direction away from the post to an excessive extent.
