My TV didn’t last that long! But our first Wedgle is still operating today. It’s proof that our equipment is made to work in the field. But how many trees? The arborist treats approximately 800 trees a year. Why did he choose ArborSystems? He did not want to drill trees to treat them. Multiple or annual treatments can be made without injuring the tree. The Wedgle injects chemicals directly through the bark without drilling. No air enters the sapwood, so chemical is readily absorbed. Vascular system is undisturbed, maintaining nutrient movement upward and laterally. Click here for more info
