My white peach never grew much. It is about 8 - 9 years old and lots of sap is weeping out of the branches. I don't care so much about the stunted growth, but what does all the sap leaking out of the branches mean?

Thanks

In most locations Peach borers. https://extension.colostate.ed... In the southeast, the lesser peach tree borer is worse. https://content.ces.ncsu.edu/l.... This one attacks the whole tree and you will see gum oozing from the base to the tip of branches. The regular peach tree borer concentrates on the roots and trunk

It sounds like you have Gummosis, a fungal disease caused by a Botryosphaeria fungus. In some areas like Florida it's extremely common, and since there are no effective fungicides control can become a complete nightmare.
Since you mentioned stunted growth I suspect your tree has been water-stressed, which is the very first cause predisposing Prunus sp to gummosis.

The only thing that can be done about gummosis is disease management: fallen leaves should be raked and destroyed, pruning should only be done during a dry spell, weeds around the base of the tree should be eliminated to reduce moisture and finally any new wounds on other Prunus trees should be immediately sealed with pruning mastic.

If you cannot afford this level of care or the disease is progressed too far, I suggest promptly eliminating the tree and burning it.

OK, thanks. Sounds drastic!

I had a few plum trees I had to get rid of. Black knot. I'm in moldy zone 6. I wonder if the cicada ruined it from a few years ago.
