After a fall frost and the foliage has died back, horseradish can be dug up and divided. Larger parts are harvested and smaller parts are replanted to produce next year's crop. Midsummer flowers should be removed to save the plant's energy and prevent seeding.
If horseradish is left untouched, it can become invasive, spreading by underground rhizomes.
