What can I do now so I will have peaches on my peach tree.
I live in Southern CA. so it's been a dry winter. I also have already used a fruit fertilzer.

The number of peaches is primarily determined by the number of "cold hours" your variety of peach tree requires to bear fruit.... in warmer climates like CA or AZ (where I live) you need a tree that requires less cold hours and higher minimum temps (40 degrees instead of 40 degrees for example).... and some varieties require a "pollinator" another peach tree of a compatible variety in order to bear a larger crop of fruit.
