Pine tree turning white

Asked July 6, 2019, 5:35 PM EDT

I have a mature pine tree where the lower branches are turning white. Looks like a substance on top of the bark. Is this harmful? What can I do to treat it?

It looks like the tree may have pine bark adelgid which produce white wooly coating that you are seeing. Below is a link to an article that will provide you with more info on this insect and it's life cycle.

You may want to consider contacting a certified arborist who could look closely at the tree to confirm this and then as applicable, offer a treatment plan. Find a certified arborist via the link below. https://www.treesaregood.org/findanarborist/findanarborist
