Plant Description
Apples are adapted to many areas of California. A cool climate is needed for coloration in most red varieties. Winter chilling requirements for most varieties (except “low chill”) are 1200–1500 hours below 45°F. Foggy days and dews can cause heavy cosmetic russetting on fruit.
Cultural Tips
Cultural practices such as site selection, soil preparation, planting, pruning, and watering are important for plant health, pest management and pest reduction when growing apple.
