Sugarcane plantings and production spread during the next century into the other Caribbean islands and into Mexico, Central America, and South America. Sugarcane Production in the USA Sugarcane is grown commercially in four states in the USA, with over 900,000 acres harvested and a value of $754 million. Jesuit priests brought sugarcane into New Orleans, Louisiana, in 1751. Commercial-scale production in New Orleans began in 1795. Sugarcane is now grown on 435,000 acres in 24 parishes in southern Louisiana. Th e value of sugarcane production in Louisiana in 2005 was over $282 million. Sugarcane has been grown in many locations in Florida since the arrival of the French and Spanish. Commercial production today is centered south, east, and west of Lake Okeechobee in the southern part of the state. Th e sugarcane industry expanded in Florida during the 1960s and har- vested acres in 2006 reached 405,000.

However, due to economic hardships, the last mill closed in 1921.
