ABSTRACT:
A tree support of self-stabilizing type including a pair of yieldable assemblies each comprising a first hook adapted to be attached to the upper portion of a stake, a second hook having a yieldable covering adapted to be attached to the trunk of a tree to be stabilized, and a tension spring having opposite ends respectively connected to the aforementioned hooks and extending therebetween. The pair of yieldable assemblies are connected between a tree to be stabilized and a pair of similar vertical stakes spaced at opposite sides of the tree and spaced from the tree sufficiently that the springs of the assemblies are under at least limited tension and the assemblies being operable to return the tree to initial vertical position regardless of the direction in which the tree is swayed by wind or otherwise.
