Selecting Fruit Trees for Southwestern States
The southwestern states encompass plateaus, mountains, and canyons with vast variations in USDA growing zones ranging from chilly zone 4 to warm, arid deserts with summer highs well above 100 F. (38 C.). In the warm areas of the Southwest, cherries and many other types of fruit trees have a difficult time because they require a winter chilling period of 400 hours or more, with temperatures between 32-45 F. (0-7 C.). Chilling requirement is a major consideration when selecting fruit trees for southwestern states. Look for varieties with requirements of 400 hours or less where winters are warm and mild.
