Neighborhood Cedar Trees Dying

Asked October 29, 2019, 10:59 AM EDT

I have recently noticed in my neighborhood that entire Cedar trees are turning and staying brown with the needles remaining attached to the tree. Are these trees dead or dying? What may be causing this and how can it be remediated?

Multnomah County Oregon

Without a picture, If this is western red cedar, I'm guessing, but each fall, and especially in certain years, we see extensive browning of leaf clusters, or branchlets. These hang for some time and eventually fall. the tree survives, and this is a way that cedar loses foliage. But there will be green foliage still on the tree.

However, if the entire tree turns brown and stays brown, it is likely the tree is dead. Cutting into the branch or buds should reveal if they are alive or not.

It is important to know the species of cedar to help understand what is going on.

Do you know if this is Port orford cedar? We have a non-native root disease specific to Port Orford cedar that kills it.

We have seen western red cedar decline due to drought recently:

Can you identify the tree, and send a picture? Or perhaps one of these links explains things?

Hope this helps.
