Peach Diseases, preventing
About 15 years ago I planted a peach tree that died off that year but a shoot came up from the root and grew, probably not good fruit stock. So I let it grow and for the past few years there have been a few blossoms and a few peaches. This year there are many blossoms. Last year the peaches were small, had spots on them but worst was a clear oozing goo that came out of each. What is that and how do I prevent it? What about the spots?
What I can put on the tree now with blossom and throughout the season to protect the peaches? Is dormant oil spray for that or for before the flowering?
