I would like to know what I can treat the peach tree in the attached photo with so that the tree will return to being healthy. I acquired 6 fruit trees with the purchase of my new home in Caroline County. The previous owners informed me that they used organic practices with the fruits. One plum tree never leafed- but I don't think they realized it was dead. There are two peach trees and now one has developed this seeping sap- which is quite hard on the outward bubble edge. Some fruit on the second tree is now showing the same problem. I sprayed for Japanese beetles using "seven" spray.
