Cherries grow best in a moderately cool climate. They are consumed fresh as well as processed for juice and other products such as wine. Sweet cherries are mostly grown in Oregon, Washington, and California because of the semi-arid climate. Lack of rain at harvest prevents cracking and rotting of the fruit. Tart cherries are more tolerant of rain and are grown in several states east of the Rockies. Michigan, Wisconsin, New York, and Pennsylvania are major tart cherry producing states in the East and Midwest.
