There is no control for black rot once it is established in a planting. Black rot is caused by a bacterium that is seed-borne or that can be transmitted by transplants. Chinese cabbage is more susceptible to Alternaria leaf spot.īlack rot causes the most serious damage and appears as V-shaped lesions down the leaves and spreads into the water conducting system of the plant. Cabbage is more susceptible to wire stem and downy mildew than Chinese cabbage. Ĭommon disease problems include black rot, wire stem, damping-off, downy mildew, Alternaria leaf spot and watery soft rot. For more information, see HGIC 2203, Cabbage, Broccoli, & Other Cole Crop Insect Pests. Several worms (imported cabbageworm, cabbage looper, diamondback moth caterpillar), harlequin bugs, cabbage maggots, aphids and flea beetles are the major insect problems. Root-prune with spade or trowel or twist the stalk to break some of the roots and reduce water uptake. Head cracking or splitting occurs due to excessive water uptake and growth near maturity. Cabbage can be stored at 34 ☏ and 98% humidity for up to five months. ![]() Store all harvested cabbage in the refrigerator. Cabbage will “sunblister” and lose weight in direct sun. Once cut, move it out of the sun as soon as possible. Harvest cabbage when the head is firm and has reached adequate size depending on the variety and growing conditions. Harvest & StorageĬabbage should be ready for harvest 60 to 80 days after planting transplants. ![]() Mulching can help conserve water and reduce weeds. It is important to have a constant uniform moisture supply to produce a high-quality crop and to have the spring crop mature before high summer temperatures. The critical periods for moisture are stand establishment and crop maturation. Light sprinklings will encourage shallow rooting of the plants. Water sufficiently to moisten the soil to a depth of at least 6 inches. The garden should be watered in the morning so that the foliage is dry before dark. Water the garden to provide a uniform moisture supply to the crop. More frequent side-dressing may be required if the garden soil is sandy or leaching rains occur. Side-dress with 34-0-0 at 1 pound per hundred feet of row or 15.5-0-0 (calcium nitrate) at 2 pounds per 100 feet of row. These vegetables should be side-dressed once during the growing season. If a soil test has not been taken, apply 5-10-10 at 3 pounds per 100 square feet before planting. Information on soil testing is available in the fact sheet HGIC 1652, Soil Testing. FertilizingĪ soil test is always the best method for determining the fertilization needs of the crop. Have your garden soil tested several months prior to planting and adjust soil pH according to recommendations. Chinese Cabbage: Pak Choi Type – Joi Choi (hybrid)Ĭabbage grows well on a wide variety of soils, but a well-drained sandy loam with high organic matter content is preferred.Cabbage: Bravo, Market Prize, Rio Verde, Savoy Express, Tropic Giant (hybrid), Green Jewels (hybrid).Cory Tanner, ©2016, Clemson Extension Cultivars Joi Choi is a pak choi hybrid that is known for its uniform growth habit. Direct-seeded plantings should be thinned to the desired stand when the plants are in the three-leaf stage. ![]() It is also desirable to have an area that is protected from the wind when seeding these crops. It is critical to keep the soil moist during seedling establishment. Loamy to sandy soil is best for direct seeding. Varieties for sauerkraut are spaced wider.ĭirect seeding is possible, especially for the fall crop. For 2- to 3-pound heads, transplant plants or space seed 9 to 12 inches apart in rows 36 to 44 inches wide. Mature cabbages can withstand temperatures as low as 18 to 20 ☏.Ĭabbage transplants are best for spring plantings, but fall plantings may be directly seeded into the row. When planted in the spring, cabbages must be planted early enough to ensure that they are harvested before temperatures become too hot. Like many other cool-season crops, they will “bolt” or produce a flower stalk if exposed to a prolonged cold period of 10 or more continuous days of temperatures between 35 and 50 ☏ following a favorable growing period. The leaves are slightly wrinkled and thinner than the leaves of regular cabbage with wide, crisp midribs. Smith, ©2015 HGIC, Clemson ExtensionĬhinese cabbage forms dense heads that may be very upright and tall (Michihili types) or round and barrel-shaped (Napa types). Cabbage ( Brassica oleracea, Capitata Group) is a cool-season vegetable that grows best in well-drained sandy loam soils that have high organic content.īarbara H.
