Easily grown in organically rich, consistently moist, well-drained loams in full sun. Cabbage is typically grown in the cool temperatures of spring or fall. It needs cool temperatures to produce the best crop. Plants generally grow poorly when daytime temperatures consistently exceed 80 degrees F. For spring planting, sow seed indoors 6-8 weeks before the last spring frost date or sow seed outdoors about 4 weeks prior to the last spring frost date. In the alternative, transplants may be purchased from local nurseries. In either case, seedlings/transplants may be planted outdoors 1-2 weeks prior to last spring frost date. For fall harvest, sow seed indoors about July 1 and plant the seedlings outdoors in mid-August or sow seed directly in the garden in early to mid-July. Generally transplants (from home grown seed or from nurseries) should be planted about 12-18" apart in rows that are 2' apart. Keep plants consistently moist. Apply mulch around plants to protect the shallow roots, reduce weeds and retain soil moisture. Cabbages may be picked after the firm heads form. Rotate crops to avoid soil borne diseases.

Noteworthy Characteristics

Brassica oleracea (Capitata Group), commonly known as cabbage, is a cool weather vegetable that is grown for harvest of its edible leaves. It is a biennial that is grown in St. Louis as an annual. It produces a dense 3-4 pound head of cabbage in 80 days during the first year of its biennial life.
