Abstract: A tree support system and method for temporarily supporting a tree that is easy to install and remove, and does not impart damage to the tree. A plurality of one-piece molded support blocks which are designed to be strapped to the trunk of a tree encircling the trunk. Each support block is specifically configured to avoid causing damage to the tree by including a padded tree-engaging surface to protect the tree from damage, and a pair of strap-receiving loops which are disposed on the block so as to be spaced from the tree trunk such that securing straps are maintained in spaced relation from the tree trunk. The support blocks further include an angled cavity having a generally rectangular cross-section sized for receiving a wooden support post or leg, such as a 2×4, thereby ensuring proper angled positioning of the support posts.
