FAQ – Can you treat trees in the fall using trunk injection?

Yes…with ArborSystems Wedgle Direct-Inject Tree Injection System. Trees can be treated with the Wedgle anytime the tree is actively growing as the product is translocated with the sap. It does depends on your area…you can keep treating for two-year control of Emerald Ash Borer until six weeks before the first frost with Boxer Insecticide-Miticide. Most other treatment methods have to be done in the spring. Urban foresters, arborists and tree care professionals that use the Wedgle say that you can treat trees all night and all day long but at night, you will need flashlights and truck headlights to get a few more hours into the work day.
