Abstract: 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 driven lengthwise into the ground and pulled into a flat transverse 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 receive an end of the cable. A cam type or ratchet type cinching buckle on the belt allows passage of one end of the belt therethrough for tightly cinching the belt about the circumference of the tree trunk and releasably grips the belt in the encircled position.
