How to grow cabbage in South Carolina, step by step
- Start seeds indoors (Feb 4 – Feb 18). Sow seeds ½ inch deep in seed-starting mix under bright light. They take 5-10 days to sprout, fastest in soil around 75°F. Harden seedlings off for a week before they go outside.
- Prepare the bed. It needs at least six to eight hours of direct sun a day and loose soil at least 18 inches deep, with a pH between 6.0 and 7.5. Dig in compost before planting.
- Plant out (Feb 25 – Mar 14). Space plants about 15 inches apart in rows 30 inches apart. It handles frost well, so it can go out before the last frost date. As a cool-season crop it does best before summer heat arrives in South Carolina.
- Water and feed. Give it steady, even moisture, about an inch of water a week from rain or the hose.
- Watch for pests and problems. Pests: cabbage worm, cabbage looper, aphids, cabbage root maggot, flea beetle. Diseases and disorders: clubroot, black rot, downy mildew, fusarium yellows.
- Harvest (from about May 3 – Jun 12). Cabbage takes 60-100 days to reach harvest. Tighter spacing (12 in) gives smaller heads better for one meal. Split heads mean it is past ready or got a sudden drink after dry weather.
