Cities tell us that they are very concerned with the safety of their citizens when they are treating trees. Using a system that has to be mixed and/or filled at the job site has a great potential for spilling and other well-being issues for the home owners as well as the general safety of its residents. This topic is something that ArborSystems has been concerned about and has addressed from the beginning. There is no mixing with the ArborSystems Wedgle Direct-Injection Tree Treatment System. No chemical drift or run off. No guarding or waiting for uptake. It is a complete closed system. For more information, click here.
