           A  tree  supporting  system  includes  a  non-elastic  flexible
         tree collar belt which encircles the tree trunk with movable
         belt loops thereon, adjustable cables attached at one end to
         the loops, and ground anchors at the other end that are driv-
         en lengthwise into the ground and pulled into a flat trans-
         verse position in the ground. The belt and the belt loops are
         formed  flat  non-elastic  webbing.  The  belt  loops  having  an
         upper loop eye at an upper end slidably mounted on the belt
         and a lower loop eye at a lower end sized and shaped to re-
