I have a mature pagoda dogwood (cornus alternifolia) on the NE side of my house. About mid summer the leaves on the upper half of the tree wilted. On the lower half of the tree the leaves are fine. I examined the upper branches and am not sure I am seeing. Am having no luck finding similar symptoms online.

Thank you for the question. More information is needed to be able to diagnose your problem because the symptoms you describe could be caused by insect, disease, or environmental factors. Refer to these Extension publications to learn about environmental, disease, or pest problems of pagoda dogwood and then go out and carefully examine the tree trunk, branches, needles, and growing conditions. You may even need a hand lens to spot some disease signs.
Thank you for contacting Extension.
