pine tree blight/fungus #416284

Asked July 23, 2017, 6:24 PM EDT

I have several pine trees on my property that appear to be dying from the inside out. Some of the branches seem to be completely dead while others on the same tree are dead on the inside-from the trunk out and then on the tips of some of the branches there seems to be new needles. Is there anyway to save these trees? This is happening to several of my pine trees in 3 distinctly different areas of my property. It is also happening to some of my neighbors pine trees. Any help you can give me with this problem would be greatly appreciated. Thank you, Elaine Andreasen

Thank you for the question.    It is risky to make a diagnosis of tree problems based on photographs and the best way to know for sure what's going on with the tree and to decide whether it can be saved or not is to call a certified arborist who can view it up close in the context of its surroundings.  Here's how to find such a professional:
This is good advice considering the the scope of the problem with your and the neighbor's trees.  Without very close up photos of the branches and the entire tree, our help is limited.  The problem could be disease, insects, or cultural factors.
Please use our self diagnostic program to try to narrow down the problem.  You may need a hand lens to thoroughly inspect the remaining needles for signs of disease or insects.  Our disease identification program might help as well:
It's hard to tell from the photo, but are you sure the tree is a pine and not a spruce or fir?  Identifying the tree accurately is the first step in diagnosing the problem.  This publication might help you:
