Huge for trees

Asked October 15, 2019, 11:10 AM EDT

I’m concerned for our for tree and others in the surrounding area. Many of the branches (fir)have turned. Orange just recently , I would guess less than 1/10th. Is there anything we can do to promote health and should we worry about the tree dying?

Evergreens naturally drop the oldest foliage this time of year, so a certain amount of brown or orange needles throughout the plant is normal. The tree in your photos is a Western Red Cedar. Excessive dieback is cause for concern. Here is the page from the PNW Pest Management Handbooks describing cedar flagging and steps you can take to limit it: https://pnwhandbooks.org/plantdisease/host-disease/cedar-cedrus-spp-cedar-flagging Most conifers are continuing to show serious drought damage and many are dying. Homeowners can do supplemental deep watering in summer. Here’s a current article from OSU Extension: https://today.oregonstate.edu/news/western-oregon-conifers-continue-show-damage-due-drought
