Peaking Cherry tree disease
I have a couple of Peking Cherry trees that are losing their leaves and have numerous small square and rectangular bites from the bark of the tree. They are half way up the tree and located in mostly one area. Can I spray the tree with fruit spray? What should I do about the marks in the bark?

This appears to be the work of a sapsucker woodpecker. See this info: https://www.na.fs.fed.us/spfo/pubs/howtos/ht_sap/sap.htm
