Norweigan Pine Needle Issue #865628
Asked April 23, 2024, 3:41 PM EDT
My two Norweigan Pines have browning needles at the ends of the branch and appear to be making their way inwards. I don’t believe it is needlecast, but maybe some virus or cold wind damage from the Winter. However, this issue starting showing up last Fall. Could you help me to diagnose what’s going on and possibly some direction. So far I have been told to prune the bad limbs and treat with a fungicide.

Also, there does not appear to be any small bugs/mites/etc, or sap oozing out from the limbs.

Hi again Robert -
I read in an extension notice today that you aren't the only one with these needle problems right now. You can send your photos and question about the needles to the MSU plant and pest diagnostic lab for their opinion. It is free to send them an email.
The lab email is <personal data hidden>
If the lab needs a sample they will let you know. There will be a small fee for that part of the service.
Good luck!
