All peach trees bloom in the spring and ripen from early summer to early fall. The month when they bloom depends on the variety of peach and the weather. All peach varieties have different winter chilling requirements, without which they will not bloom and yield peaches. Native to China, peaches (Prunus persica) can be grown in U.S. Department of Agriculture plant hardiness zones 5 through 8.
The winter chilling requirement necessary for peach trees to bloom and yield peaches is between 33 and 45 degrees Fahrenheit. Peach trees need chilling for a total number of hours -- they don't need to be successive hours -- at that temperature, ranging from  750 to 1,000 hours.
