Hello!

Thank you for contacting Ask an Expert.

Here is the response provided by Annie Klodd, Extension Educator - Fruit and Vegetable Production....

If the leaves on entire cherry tree branches have turned brown in the middle of the season, then the tree very likely has Verticillium wilt. This disease can kill entire cherry trees. Unfortunately, if the tree has this disease then the affected parts of the tree will not recover. Remove the dead branches. If the whole tree is dead, then the whole tree should be removed. Yes, you can burn the wood. Here is an article on verticillium wilt: https://extension.wsu.edu/chelan-douglas/agriculture/treefruit/horticulture/cherryverticilliumwilt/

Please note that this is not an official diagnosis, as I have not seen a photo of the tree, and no samples have been submitted to the Plant Disease Clinic for confirmation.


Hope this helps.
