TREE INJECTIONThere are many schools of thoughts concerning tree injections. While research has shown that fungicides and certain nutrients (such as iron) can be placed into the tree's xylem quickly, it can't be ignored that holes or wounds are created in the tree. These wounds have to heal, and that may take some of the tree's energy. Wounds provide an opening for insects or diseases.
Research does indicate that repeated injections will harm a tree. Only a professional or certified arborist should inject a tree. Make sure to read all literature provided.
