Incense cedar die back

Asked November 23, 2019, 9:02 PM EST

Are there any remedies to this issue of incense cedar dieback? I read that it’s due to branch canker dieback disease, and it seems quite common now.

Clackamas County Oregon

Thank you for your question. There are two known issues with this phenomenon, one of which is the canker. But, as the following OSU Extension article indicates, since 2015, at least two causes have been identified: http://blogs.oregonstate.edu/treetopics/2014/06/27/whats-causing-die-back-incense-cedar/ Without having a chance to examine your tree(s), we cannot suggest a solution, if any exists. If you can bring plant tissue, as well as photos of your tree(s) to the Extension office, we can try to diagnose the issue(s). The office is at 200 Warner-Milne Road, Oregon City, and has staffing 9am-noon, and 1-4 pm weekdays. Good luck!
