Q.Dying Peach Trees
What could be killing my peach trees, and can I turn them around? I have 2 out of 3 peach trees that are dying. The leaves are turning yellow and drying out and the fruit is shrivelling. I have had issues with this sappy stuff that comes out of the bottom of the tree and along the branches. There is also a sawdust look at the bottom of the tree. I dug up some of the stuff at the bottom and there were bug/larvae shells there. Can I save my trees, bring them back?

It sounds like you are dealing with peach borers. Here is a site that give more detailed information on how to treat for these pests.
