A general tree support method attaches and binds a fiber buffer to a tree support at a predetermined height of a tree stem, and causes a scratch to be generated at a contact portion of the tree support as the tree stem grows. In addition, in order to increase the support force on the lower ground surface of the tree support, the support is widely widened to the outside. Then, passing is hindered, and a turnover accident of a pedestrian occurs in a narrower road space. The present invention allows firm tree support force to be generated even in a narrow road space, and allows the autonomous tree support force of a planting tree to be automatically canceled while extending along with the growth of tree. In particular, a plurality of attachment plates (h) are attached so as to coincide in the vertical direction with at two upper and lower sides of a tree stem. Each of the vertical attachment plates (h) fixes a tree support in which a tree support fixing cap (p) is inserted on both sides of the upper and lower sides to be able to support a tree in a minimum space. Since the attachment plate is fixed by an attachment plate fixing needle (hn) which is stuck and fixed to bark or deeper between the attachment plates and the tree stem so as not to be easily separated by external force, the growth of a tree is not affected, and automatic detachment is secured when bark becomes thicker according to the growth of a tree. The tree support materials of the present invention can be reused, and design factors are applied to each of the materials. Thus, aesthetically excellent appearance is secured, and the method of the present invention can be functionally very effectively performed.COPYRIGHT KIPO 2018일반적인 수목지지방법은 수목줄기 일정 높이에 수목지지대에 섬유 완충재를 사용 부착하고 결속하게 되는데 이는 수목줄기가 생장함에 따라 수목지지대 접촉 부위에 생채기가 발생하게 된다. 또한 수목지지대 하측 지표면에서는 지지력을 높이기 위해 외측으로 넓게 벌어져 통행방해 요인이 되고, 비좁은 도로 공간에서는 보행자의 전도사고가 발생하게 된다. 이 발명은 비좁은 도로 공간에서도 견고한 수목지지력이 발생되도록 하며, 수목생장과 함께 신장되면서 식재 수목의 자체 수목지지력이 발생시점에서 자동 탈락이 가능하도록 한
