Consider your options…
Do you protect your ash tree? Ash trees can be saved if they are chemically treated. Trees may need to be treated throughout their lives. If your ash tree is healthy and is enhancing your landscape, it may be worthwhile to protect your tree. Healthy trees are valuable and provide many benefits such as home energy savings, property value, shade and reducing storm water runoff. For more info on chemically treating ash, see www.emeraldashborer.wi.gov Click on the Homeowners tab for further links on tree or insect identification as well as chemical options. Should I remove my ash tree and replace it? Trees which are unhealthy, have structural problems, are planted in poor sites and are not important to the landscape, and/or showing many outward signs of EAB infestation should be considered for removal and replacement. Once EAB gets established in Ashwaubenon, trees left untreated will die. Tress killed by EAB quickly become a liability due to limbs breaking off, and become more difficult to remove since they shatter when hitting the ground. Who should I hire to treat and/or remove my ash tree? Work with a professional arborist. Hire an arborist which is insured, preferably one that is an International Society of Arboriculture Certified Arborist. Ask for references. If you hire an arborist to chemically treat your tree, make sure they are a WI Certified Pesticide Applicator. Get a couple of estimates from different arborists.
