Plum Tree w/running sap

Anonymous added on September 9, 2015 | Answered

I really have two questions. 1. What product should I use to fertilize my plum tree and how do I do it? 2. I have been told the silvery looking stuff on the bark of my plum tree is some kind of fungus. What is the name of this fungus and how do I treat it?

It might be bacterial wetwood or peach borers or canker, depending on how the sap looks. These articles will describe the nature of the running sap for each problem and will suggest solutions:
