Last year my eight Red Haven peach trees all flowered but did not have a single peach on any of them. They all fruited the year before; they are young trees and are in full sun. The cherries and apples fruited well, so I don't think it was a late frost. What could be wrong? If they don't fruit this year, should I pull them up?
It sounds like there may be a phosphorus deficiency in soil around those trees. Have the soil tested and add phosphorus rich fertilizer to the soil. Here is more information:

A 5-year-old Red Haven tree blossomed and leaves appeared, thin shaped and then began to turn brown, twist, and dry. The blossoms wilted before they fell. What's going on? There's another very healthy tree right next to it.
The tree could be affected by peach borers. This article will help determine if this is the problem and what to do about it: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-borer.htm
