The company also once set the record for deepest oil well in Ventura County before abandoning the well in 1949. The well like many others were in search of oil but oil was never found on Limoneira properties despite several companies participating in drilling, including Superior Oil Company, Richfield Oil Corporation, Humble Oil, Unocal Corporation and Standard Oil. Throughout its history, it has employed foreign labor including Japanese and Mexicans. In 1924, after the Immigration Act of 1924 which barred Japanese immigration, it particularly focused on Mexican labor. Since the 1970s, Limoneira has also been a leading lemon supplier to Japan and also distributes to Korea, China, Philippines and Thailand. In 1985, Limoneira partnered with Samuel Edwards Associates to become Limoneira Associates until Limoneira become one company again in 1990.
