PROBLEM TO BE SOLVED: To provide a supporting tool for a planted tree dispensing with difficult works such as the driving of a post into the soil outside of the planting hole and getting sufficient holding force even in a park, garden, or street having soft dressing soil. SOLUTION: The upper part of a post 2 such as a steel pipe is placed along the trunk 1 of a tree and the lower part of the post is embedded in the soil. Plural posts 2 having the above structure are connected with each other with one or more ring-shaped connection parts 3 to encircle the trunk 1 of the tree. The lower part 2a of the post 2 is provided at its tip with a stabilizing plate 4 stably supported in soil to fix the position by the balanced soil pressure from above and below when buried in the soil. The stabilizing plate 4 is supported by the soil with the face extending outward from the post to prevent the sinking and extraction and, accordingly, a sufficient holding force can be attained even in a soft dressed soil.
