Cabbage Growing Basics

Cabbage was developed from wild Mediterranean brassicas and has been cultivated for thousands of years. Varieties may form round, flat, pointed, or elongated heads in shades of green, red, and purple, while savoy types are known for their crinkled leaves.

Cabbage is a cool-season biennial usually grown as an annual. It forms its best heads through steady growth, even moisture, and mild temperatures.

Start seeds indoors about 5–7 weeks before transplanting. Set hardened spring plants outdoors roughly 2–4 weeks before the expected last frost.

Cabbage grows best in cool weather, generally around 60–65°F. For a fall harvest, count backward from the variety’s days to maturity and allow additional time for slower growth as days shorten. 

Sow seeds about ¼–½ inch deep in moist seed-starting mix. Provide bright light and cool, steady conditions after emergence to produce compact, sturdy seedlings.

Harden plants gradually before transplanting. Space compact varieties about 12–15 inches apart and larger storage types 18–24 inches apart. Wider spacing generally produces larger heads.

Choose a site with full sun and fertile, well-drained soil enriched with finished compost. Cabbage benefits from steady fertility, but excessive nitrogen can produce loose growth and delay firm head formation.

Keep the soil evenly moist, especially as heads begin to form. Mulch with straw, shredded leaves, or another organic material to conserve moisture, reduce weeds, and moderate soil temperature. Avoid deep cultivation around the shallow roots.

Harvest when heads feel firm and have reached a useful size for the variety. Cut through the stem just below the head, leaving a few outer wrapper leaves attached for protection.

Do not leave mature heads standing too long, especially after heavy rain, because they may split. Some plants will produce several small secondary heads if the lower stem and outer leaves remain in place.
