Potato cultivation and ridging or "hilling" are typically performed simultaneously. In the same spirit, systemic insecticides, fertilizers, or other materials may be either: surface-applied and left uncovered; broadcast and incorporated near the rows; or sidedressed near the rows and covered during hill construction. Systemic insecticides are typically handled in this manner.
Ridging provides a number of advantages including reduced sungreening, improved weed control within the rows, and improved harvest conditions. Ridges are typically broad and 8 or 10 inches tall.
