PROBLEM TO BE SOLVED: To provide a planted tree-supporting structure which is obtained by spanning a spanning member on the upper portions of support piles above the root ball of a tree and then tightening the spanning member so that the support piles are integrated with the root ball, thereby generating a pressing force to the side surface of the root ball and a pulling resistance force in the ground. SOLUTION: This planted tree support structure is formed by obliquely driving plural support piles 3 into the deeper ground than the root ball 2 of a tree along the peripheral side surface of the root ball 2 so that the lower portions of the piles 3 are directed to the inside of the root ball 2, spanning a spanning member such as a wire on the upper portions of the support piles 3, and then tightening the spanning member with a winch 7 in the contraction direction so that the support piles 3 surrounding the root ball 2 are integrally and approximately adhered to the peripheral side surface of the root ball 2.
