Horseradish Growing and Maintenance Tips

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.
