Tree issue in Van Buren County

Asked August 15, 2019, 10:01 AM EDT

Our client has a tree that appears to be dying from the ground up. She has three out of five trees that seem to be affected. The trees are approximately 33 years old. She has already had to cut down one due the same issue. If she has to remove all of them, does she have to remove the stump as well? Does she need to spray? If so, what product? Thank You.

The tree looks like Douglas-fir. Douglas-fir has a couple of needlecast diseases - Swiss needlecast and Rhabdocline needlecast. We also see Armillaria root rot and since it is not native we can see winter injury. It is hard to tell what may be going on from your photos. I would suggest you have them send a sample to MSU Diagnostic Clinic to determine the exact cause.
