Greens: Mustard, Turnip, Collard and Kale
Greens are grown for the tops only. The proper size at harvest varies with the crop and growing conditions. Kale is allowed to grow to take two cuttings off one seeding. Some growers continue to strip kale leaves as the plants grow, thereby extending the harvest season for some time. Greens are usually on a constant field rotation to avoid club-root infestation in the soil. Field seeding begins in early April and ends in early August.
