A few things could cause this. First, it could be a chilling issue. If a peach tree gets just a little bit too little chilling in the winter, it will button the fruit, which means that it tries to grow them, but they will be deformed, stunted or fail to mature. Since no one really had a cold winter this year, it is likely that chilling could be a factor.

If this is the case though, the tree will drop the fruit in late spring or early summer.

If your tree is at least 3 years old and it carries the small, immature fruit throughout the season, that may be your problem.
