Answer: I would move the trees (try not to sever too many roots in the process). Peach trees need well-draining soil so amending the planting area (not just the planting hole) will help the roots become established. You might be surprised how adaptable the root systems can be if they receive adequate water and annual fertilizing. Make sure your trees are getting all day sunshine to help them blossom and set fruit. As your trees become established and more mature, they should set more fruit.
There are two major problems peach trees face in your gardening region - brown rot and plum curlico. I suspect the worms you've found are from plum curlico. Brown rot is a fungal disease and you can help your tree avoid becoming infected by spraying with Captan (be sure to read and follow the label directions -timing is important) and you can control insect damage by spraying with Endosulphan (Thiodan). Again, read and follow label directions.
Best wishes with your peach trees!
