A tree trunk restraint collar for supporting young or transplanted trees or restraining established trees to a desired position. The preferred round collar is flexible and split at one place so that it may be twisted apart to be installed around the trunk. Thus placed, it is allowed to reform to its natural, circular shape. Some form of cord or wire is then looped through collar eyelets and around the outside middle of the collar, to secure the collar within its closed and circular condition at the one end of the cord and to secure the collar to support posts at the other end. The ring fits loosely around the trunk to allow growth and flow of natural fluids within the trunk. At the same time the ring guides and restrains the tree when forces such as wind, gravity, or the attraction of sunlight are exerted upon it. The device is economical to make and install and is effective in its function.
