We make it easy for you. ArborSystems trunk injection hardware and chemicals are all sold through local distributors. They are knowledgeable about tree care and treatment in your area and can even help you set up your own tree care business or add it to your existing company. And ArborSystems helps tree care professionals after the purchase. Once the Wedgle Direct Injection Tree Treatment System registration card is returned to our office, we add you to our “Find a Tree Care Professional” database that is used by homeowners on a daily basis.
