Chinese Cabbage, Napa Cabbage
|Cabbage, Broccoli, Collards and Cauliflower, plus the less-often-grown Kohlrabi, Mustard Greens, Chinese Cabbage and Turnips, all belong to this family. All are cool-weather vegetables, rich in vitamins A and C and a good source of fiber. Best when matured during fall or when temperatures remain between 40º and 70º F. Cole crops tolerate early spring and late fall frosts, but aside from Collards, do poorly in hot weather. For summer crops, start seed indoors and transplant seedlings outdoors 4 to 6 weeks before last frost. Heavy feeders of nitrogen and potash, they like a soil pH between 6 to 7.5. Sow shallow-rooted plants no more than 1 inch deep. For fall crops, start seed from mid to late summer. In mild winter areas, plant from late summer through early spring for harvest from fall to spring. Watch for many pests including cabbage lopper, root maggots, cabbage worm and flea beetles, plus diseases such as club root, damping off, mildew and fusarium yellows. To reduce the risk of diseases and pests, plant where cole crops have not been grown for 3 years, and maintain proper soil pH.
Use its loose, upright heads of sweetly flavored and aromatic leaves fresh or cooked in salads, soups, and stir-fried dishes. Goes to seed in hot weather. Grows best in hot summer areas, with constant moisture, if planted 3 monthes before fall frost. In mild winter areas plant in fall for spring harvest. Seed transplants poorly, so start in peat pots or sow where plants will grow.
