About 4 or 5 years ago we planted a dwarf peach tree. Each spring it produces some flowers and then the peaches start to form. When the peaches get to approximately one-inch in diameter they all fall off the tree. What do we need to do to get the tree to bear edible fruit? So far we don't even have one peach from that tree.
Sounds like the fruit may not be pollinated, according to these peach answers from Texas A&M. Here are some care tips, including suggestions on pollinating.
