Cabbage in South Dakota's Climate

Your cold climate is excellent cabbage country. Transplant 2-3 weeks before your last frost — cabbage handles frost well. Fall cabbage is equally rewarding: start indoors in mid-June, transplant in mid-July, and harvest dense, sweet heads after frost. Storage varieties like Danish Ballhead keep for months in a cold garage or root cellar.
