Cultivation in California

The avocado was introduced from Mexico to California in the 19th and has become a successful cash crop. About 59,000 acres (240 km2) – some 95% of United States avocado production – is located in Southern California, with 60% in San Diego County.[43][44] Fallbrook, California, claims the title of “Avocado Capital of the World” (also claimed by the town of Uruapan in Mexico[45]), and both Fallbrook and Carpinteria, California, host annual avocado festivals. Avocado is the official fruit of the State of California.[46]

Due to increased Southern California water costs, they are now costly to grow. California produces 90% of the United States’ avocados, not Mexico.
