Emerald Tree Care has been treating in Arlington Heights successfully now for several years. We use a NON-drilling method to inject ash trees. We also fertilize them and keep them healthy with insecticide also added to the soil. Time will certainly tell if the repeated drilling of ash trees in the city will fail like all of the repeated drilling of elm trees has failed in Northbrook, Illinois. As a Board Certified Master Arborist at the very top of my profession, I will not subject my customers ash trees to the damage caused by repeated drilling.
