Insects, Disease and Diagnosis

Oak wilt in Shorewood

The methods our Wisconsin plant health care specialists use are designed with your trees well-being and long-term health in mind. Our methods preserve beneficial insects and limit spraying through the use of careful PHC management, tree trunk and soil injections. At Wachtel, we place high value on the science of tree care in Wisconsin. We only treat what is needed based on insect and disease life cycles with narrowly focused and targeted applications. 

Site inspections and problem diagnosis:

Our Wisconsin tree service provides thorough site inspections to identify and diagnose plant health issues. The certified arborists at Wachtel Tree Science have the experience to provide effective treatment options for your sick trees. Treatments range from soil systemic insecticides, spray programs and trunk injections to site ammendment and girdling root excavation.
