Hackberry dropping leaves.....

Asked May 28, 2017, 11:03 AM EDT

All of our Hackberry trees, about a dozen, are all dropping their leaves. Do not see any insects and I know it's not drought. All our other types of trees look fine, just the Hackberrys. Thanks Jim Lageson Ellendale MN

I'm sorry that your hackberries are not doing well. You may have already checked out the website below that lists possible causes of problems with hackberry trees, some of which are fungal diseases. http://www.extension.umn.edu/garden/diagnose/plant/deciduous/hackberry/ Here also is a discussion about possible problems with hackberry. http://hyg.ipm.illinois.edu/pastpest/200111b.html If the information above is not consistent with what you are seeing with your trees, an arborist or analysis of a tree sample may give you a more definitive answer. A certified arborist would be able to assess the whole tree(s) and situation at your site. Some cities have an arborist on staff or you could hire one to look at your trees. https://www.extension.umn.edu/garden/yard-garden/trees-shrubs/how-to-hire-a-professional-arborist/ An additional option would be to send a sample of the tree(s)to the University of Minnesota Plant Disease Clinic for testing. The website for sending a sample is here: https://pdc.umn.edu/submit-sample
