Tree question #935914

Asked June 17, 2026, 5:17 PM EDT

Our small grove of Kentucky coffee bean trees were thriving but now many low dead branches and leaves look wilted. There is sunlight that can get to many of the dead branches. Perplexed. Wondering if anything we can do.

Unfortunately, this looks like yet another case of herbicide drift injury. Nothing to be done for these trees. This has been a bad spring for this kind of thing.
