|what is wrong with the peaches that are size of olives?
|If the flowers were not pollinated your tree will begin to develop fruits but since they are not perfect and not capable of maturing, the tree will usually drop them before they are about an inch in diameter. If your tree is self pollinating it should flower and set fruits next spring. If it is not self-fertile you'll need a second variety of peach tree in order for it to set fruits. Natural fruit drop is common, as the trees set far more fruit than they can bare to maturity. They drop pea-size to golf-ball-size fruit in May and June. Even so, to "size up" peaches, it's recommended to thin them to about a 6-inch spacing. I hope this info helps.
