Answer: Only certain varieties of peaches and nectarines will produce fruit in your mild winter area. Both trees have a winter chilling requirement (depending on variety, a certain number of hours below 45F). If your peach tree isn't developing flowers, it can't produce fruit. Without the minimum chill requirement, the tree will not consistently develop flower buds, but there may be a year with a cold winter that will result in peaches the following summer. You might try thinning the fruit on your nectarine so the tree can put its energy into fully ripening just a few fruit, instead of producing an abundance of inedible fruit.
