Cotton is machine harvested in the U.S., beginning in July in south Texas and in October in more northern areas of the Belt. Stripper harvesters, used chiefly in Texas and Oklahoma, have rollers or mechanical brushes that remove the entire boll from the plant. In the rest of the Belt, spindle pickers are used.
Cotton was grown by American Indians in the early 1500's, documented from sightings by the Coronado expedition 1540-42. The Spaniards raised a cotton crop in Florida in 1556.
