Premature Peach Fruit Drop

Question

What would cause most of the very young peaches to fall off the tree?

Answer 1

There are several things that can do this, but likely it was poor pollination. If the flowers are not properly pollinated, the tree will drop the fruit as they will
not produce a good seed. Here is some articles that you may find helpful:
