I suggest you have a certified arborist do an onsite inspection. If it is borers a systemic insecticide should take care of the problem. However, in a year of drought your trees may have other problems. A misdiagnosis could cost you your trees. Best And Happy Yardening, Nancy.
Mature Dogwood Trees Have Dead Dried Leaves
Question From: FLORIDA
Q: I have two mature dogwood trees that have dead dried leaves about one to two feet long at the end of their branches. I suspect tip boars. Is there something I can do to stop the dying branches and will I lose the trees as it appears to be severe. Thank you
