Brown Evergreens?

This past winter was particularly hard on evergreen trees and shrubs.  This spring it’s been a common sight to see evergreens with brown needles which is a sign of Winter Burn.  The University of Minnesota has a great article to help learn more about Winter Burn and how to deal with plants that are effected by it.

Emerald Ash Borer

Emerald Ash Borer, a serious pest of ash trees has been confirmed Walworth County and several other counties of Southeast Wisconsin. Homeowners can take steps to provide their trees with a measure of security but it must be done proactively.  From determining if you have an ash tree, to advising on what to replace one with, the UW-Extension and Master Gardener Volunteers are here to help. Take a look at our Ash Tree Identification publication for help in identifying your tree.  Now the question is what should homeowners do? Please see Homeowner Guide to Emerald Ash Borer Insecticide Treatments and Is My Ash Tree Worth Treating for Emerald Ash Borer?.

If you have any questions about the Emerald Ash Borer, identifying your ash tree, or to receive a fact sheet with this information, please call the Walworth County UW-Extension office at (262)741-4951 or email christine.wen@ces.uwex.edu.  You can also visit www.emeraldashborer.wi.gov.
