Bark Bummers

Bark Bummers

 

This time of year is good and challenging for Midwesterners.  The challenging?  The weather.  Nuff said.  The good?  It’s a great time to notice potential problems in trees and shrubs in the landscape.   At this point in the season, there aren’t any leaves, fruit or flowers (except for a couple species) to get in the way of seeing the damage and/or concerns on the bark. This blog post will be heavy on the photos to show examples of what to look for.  Once you find them, you can proceed to watch the specific area(s) or take action.  Please email me at jfech1@unl.edu for specific advice.
