Production of peaches in California
California is the largest grower of peaches in the United States, producing about 70% of the total. The  (CFPA) and  (CCPA) represent the industry. (Although the CFPA is a separate incorporation, it has always been operated by the CCPA's staff.) The overwhelming majority of the country's peaches are grown here,   for sales of $308.3 million. Since 1980 the total value of the harvest has been slightly increasing. The acreage (hectares) planted in peach has been declining however, down to  . Economics

From  in 2010, delivered tonnage declined to  in 2021. Cling yield shows no clear trend over the same time, bouncing between  and . Prices have been trending mostly upward, from  in 2012 to .
