Dead branches on Incense Cedar

Asked July 29, 2019, 4:27 PM EDT

My Incense Cedar has random branches turning brown. I am concerned the tree is under attack from something. Is this normal growth pattern or a symptom of a bigger problem?

The pattern of damage resembles that from incense-cedar branch canker, a fungus that affects individual branches. To diagnose, one needs to look at an affected branch for the canker on the stem. It is not deadly to the tree but makes it unsightly.

If the branch canker signs are not present, then it could simply be a sign of stress from root disturbance, poor soil, drought, or a combination of these factors.
