This invention relates to the art of certain new and useful improvements in means and methods for shrub and tree surgery, and more particularly to a use of fiberglass and fiberglass resin and hardener techniques to more effectively treat tree wounds and cavities. Such methods and means have been found more successful than other tree surgery methods now in use, i.e., the use of concrete filler, sheet metal plates, etc. for permanent tree healing and for insect and element protection. Two procedures are used, dictated by the type of injury, (1) a combination of fiberglass resin and hardener can be applied directly to damaged exposed wood tissue (where branches up to 12 inches in diameter have just been removed, or other exposed tissue areas such as trunks, roots, pruned limb ends, etc.) to serve as an effective sealant and to provide a substrata or base on which new cambium growth can readily attach, and (2) where there are large wounds or cavities a combination of properly placed fiberglass cloth, fiberglass resin, and hardener can be used to seal and/or bridge a cavity. These procedures promote new cambium growth, provides protection until the new growth provides permanent protection, strengthens the tree, prevents insect and elements egress and extends tree life.
