When trees are planted at a landscaping site, tree support is installed to protect the trees from wind or external impact. General supports that protrude to the outside hinder the aesthetics and are vulnerable to strong winds, and must be disassembled again after about two years have elapsed after installation. The underground embbeded wood post developed to compensate for the shortcomings of these general support trees is installed at least 30 cm deeper than the root of the trees in all directions by making them as close as possible to the root of the trees. The support force of the stake itself is generated when the wood post is installed on the ground, and each of the four wood post is integrally bonded with the tree root through the steel wire for landscaping, so the support force that withstands the vertical load prevents the tree from sinking, and the support force that withstands the lateral load prevents the tree from conducting through the support force. In this way, the effect of temporarily creating roots that are more than 10 years old in nature occurs. Although this support tree is a practical technology that is easy to install and has strong support to withstand typhoons, empirical research on technical characteristics is lacking. This study analyzed the tree Rootage , the relationship between wood post corrosion and tree support, iron wire corrosion, and changes in soil composition over a certain period of time after the installation of the underground embbeded wood post. To this end, we compared and analyzed the tree rootage with underground embbeded wood post twice and trees with general support trees. After the installation of the underground embbeded wood post, field surveys were conducted three times in 14 years to analyze the relationship between wood post corrosion and tree support, and changes in soil components due to iron wire corrosion. The purpose of this study is to identify the technical characteristics of the underground embbeded wood post and to provide the basic data necessary for future use in the landscaping field. The analysis results are as follows. First, it was found that the tree rootage in which the underground embbeded wood post was installed was higher than that of the general support tree. It was found that the tree was installed in the ground and did not receive external shock such as strong winds, so that the tree could stably root down and glide. Second, as a result of the analysis of the relationship between wood post corrosion and tree support, it was found that the underground embbeded wood post was not corroded for at least 3 years and was strongly bound to the root to maintain stable support. It was found that the corrosion of the pile and wire, the development of the root, and the binding force of the iron wire connecting the pile and the root were complexly related, affecting the tree support. Third, as a result of iron wire corrosion and soil composition analysis, it was found that the steel wire for landscaping attached to the buried pile main did not cause soil pollution. Based on this study, it is expected that the interest in essential landscaping materials such as tree supports will increase and technological development will take place in the future at landscaping sites.
