Spring to summer.
Throughout the United States. Ranunculus will overwinter in warm-weather areas.
Well-drained, quality garden soil.
Water deeply as needed.
Plant tuberous roots in the fall in warmer areas. In colder areas, start tuberous roots indoors in the fall or late winter, or plant them outside in the spring when all danger of frost is past.
Fertilize with a balanced plant food according to label directions.
Plant tuberous roots with the "toes" down. After the foliage dies in the late summer, dig up the tuberous roots and store them in a dry location.
