Q.Our Nectarine Tree Looks Like It Is Dying
The tree seemed ok until about 4 weeks, when half the tree has completely dried out. Leaves, fruit, and branches are completely dried. Small branches snap, they do not bend. We lost our apple tree about 3 years ago to a blight. It has been 107 degree here in El Paso for over a week. But that is normal for EPTX.

There are several blights that can infect fruit trees across multiple genera, so if the soil was not treated before planting these trees, I would say that the same disease that took your apples took these, as well.
I would think about treating the area. but this problem will require constant attention:
