PROBLEM TO BE SOLVED: To provide a tree-supporting construction method for constructing an artificially planted tree while supporting trees in various places in an urban area such as a park, a sidewalk, an exhibition ground, a parking place, a plaza, an open space or a public vacant space, wherein wood piles are mainly used in view of natural environmental destruction, and further work for support construction is much more facilitated than the conventional one, and costs for members used for the support construction can be reduced. SOLUTION: The tree-supporting construction method comprises: driving a plurality of piles into the ground along a root ball of a tree; attaching hooking tools on respective upper parts of the piles; hanging an outside hanging-around material on the upper surface of the root ball and fixedly hooking the outside hanging-around material to the hooking tools; hooking inside hanging-around material to positions separated from the fixedly hooking tools on the outside hanging-around material to be hung around the upper surface of the root ball; and thereafter tightening the outside hanging-around material via a tightening means.
