PROBLEM TO BE SOLVED: To provide a method for constructing a support for trees and a transplanter fixation tool using the construction method for a support which, when compared with the conventional technology, it is possible to fix the transplanter more reliably, and which can more suitably prevent the inclination of the transplanter relative to the vertical direction in the case where ground subsidence occurs or when a tilting force acts on the trees.SOLUTION: The method for constructing a support for trees by constructing a support for trees using a transplanter fixing tool for fixing a transplanter of a tree, is characterized by a transplanter fixing tool provided with a transplanter bottom fixing member capable of digging into the bottom portion of the transplanter, and maintains a state of the transplanter being fixed by the transplanter fixing tool, by the transplanter bottom fixing member digging into the bottom portion of the transplanter.SELECTED DRAWING: Figure 1
