White Pines

Asked July 30, 2019, 10:03 AM EDT

Hello, I have two very established white pines in my front yard next to each other. One seemed to brown and die last year leaving no needles now. The second one started turning brown from bottom up in spring and is now completely dead and all brown. Is there something I am able to do to prevent my other pines this same outcome? I know there is a disease hitting the other pines leaving the bottom dead.

The symptoms you are seeing in your white pine can be caused by several different problems. I am unable to identify it from your photo. Some potential culprits are white pine blister rust, https://extension.umn.edu/plant-diseases/white-pine-blister-rust , root rot, pine wilt nematode, white pine decline http://hyg.ipm.illinois.edu/pastpest/200613a.html , bark beetle.... I would suggest you call a local arborist to look at the tree. You could also send a sample to MSU Diagnostic Services www.pestid.msu.edu . I would call them first to get an idea of how to take the best sample.
