An underground tree stabilization device used to stabilize a tree in heavy weather. The tree stabilizer includes a cement anchor base that increases the drag through the soil and thus acts as a brake. When attached to the base of a tree, the tree stabilizer can prevent the tree from being toppled. By limiting the rocking motion and installing the cement base below the top soil, the trees natural ability to survive is greatly enhanced. The present invention is intended for mature shallow root trees, using an underground cabling system attached to a large cement base that may be formed with the tree in place.
