Judy,
Can you please send photos? That is not something common here. We cannot recommend without diagnosing.

We had a cold snap in October that affected many of our trees, seeing lots of dieback. The prolonged drought is also affecting trees. I would prune out any dead. Keeping tools clean is always a good idea to prevent the spread of anything. https://static.colostate.edu/client-files/csfs/pdfs/613.pdf

And proper watering is essential to recovery. Avoid fertilizing stressed trees. I would recommend a fall nitrogen fertilization to feed the roots.
