How does climate affect fruit growing seasons in the USA?

Climate plays a major role in determining fruit growing seasons across the USA. Regions with warm summers and mild winters, like California and Florida, have longer growing seasons and can produce warm-weather fruits year-round. Colder northern states have a shorter season for fruits that require warm temperatures, like peaches and melons. Some fruits, like apples and cherries, require a certain number of chill hours below 45°F to produce fruit. Growers must select varieties suited to their climate.
