As long as the outside temperature is above 45 degrees, you can still direct-inject with ArborSystems chemicals and our specially-designed injection tips. Why? Treatments can be made anytime during the growing season and conifers and pines growing season extends into the fall. These fall treatments provide a carryover to the following year giving a minimum of 12-month preventative and curative protection. And when you direct-inject a tall pine, you avoid chemical drift that comes from spraying into unwanted areas. No more worrying about cars, outdoor furniture or playground equipment.
