White pine needles "drooped" last sunner and are now brown on ends.
I have a 17 yr old white pine. Last summer the needles drooped (all pointing down), and now the tips of "all" the needles are brown (about 1/5 of the total length of each needle). The ground hasn't been dry. Any idea regarding the cause and what I can do to save the tree? Thanks - Dave Bergemann

Thank you for the question. We are unable to diagnose your tree's problem from the photo. Unfortunately, more information is needed to be able to diagnose the problem because the symptoms you describe could be caused by a number of factors and it's not advisable to treat a problem without first identifying it. Refer to these Extension publications to learn about environmental, disease, or pest problems of pine and then go out and carefully examine the tree trunk, branches, needles, and growing conditions. This might be hard in the winter. You may even need a hand lens to spot some disease signs.
The following publications describe any treatment that might be necessary for the various problems. If these trees are valuable to your landscape, you may wish to hire a certified arborist to come take a look. Based on the information we have, pine decline could be the problem and the second publication below discusses it.
