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 prior to the last spring frost date or sow seed outdoors about 4 weeks prior to last spring frost date. In the alternative, transplants may be purchased from local nurseries. Seedlings/transplants should be planted outside 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 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.
