Planting, Growing, and Harvesting Cabbage

Traditionally, cabbage seeds were planted on St. Patrick’s Day in northern zones. Old-time farmers believed that to make them grow well, you needed to plant them while wearing your nightclothes! Here’s our Cabbage Growing Guide with instructions on how to plant and grow this hardy, leafy vegetable—which is packed with vitamins. No PJs required!

About Cabbage

Mark Twain once said, “Cauliflower is nothing but cabbage with a college education.” In fact, cabbage is no longer viewed so poorly. We now know that this hardy vegetable is antioxidant- and nutrient-rich, and a great addition to any garden! See 5 reasons to eat cabbage.

That said, note that cabbage can be challenging to grow for the beginner gardener if you don’t have the right conditions; it only likes cool temperatures and it can be a magnet for some types of garden pests. Rotating the cabbage crop every few years avoids buildup of soilborne diseases.

Follow our guide to plant a successful crop in the spring (and/or fall) and we’ll help you provide the diligent care that cabbage needs.

Planting

When to Plant Cabbage

  • If starting seeds indoors, sow ¼ inch deep 6 to 8 weeks before the last spring frost. Consult our Planting Calendar for suggested dates.
  • For a fall harvest, direct sow seeds outdoors (or plant transplants) in mid- to late summer. If your area is particularly hot and dry, hold off on planting until late summer. Make sure that the young plants don’t dry out in the summer sun’s heat!

Choosing and Preparing a Planting Site

  • Cabbage is a heavy feeder; it quickly depetes the soil of required nutrients.
  • Prepare the soil in advance by mixing in aged manure and/or compost.
  • Soil should be well-draining: roots that stand in water cause heads to split or rot.

How to Plant Cabbage

  • Before planting the seedlings outdoors, harden off the plants over the course of a week.
  • Transplant small plants outdoors on a cloudy afternoon 2 to 3 weeks before the last spring frost date.
  • Plant seedlings 12 to 24 inches apart in rows, depending on the size of head desired. The closer you plant, the smaller the cabbage heads.

Care

How to Grow Cabbages

  • When seedlings reach about 5 inches tall, thin to leave the desired space between them. If you wish, transplant the thinned seedlings elsewhere.
  • Mulch thickly around the area to retain moisture and regulate soil temperature.
  • Water 2 inches per square foot per week.
  • The optimum soil temperature for growth is 60 to 65° F. Young plants exposed to temperatures below 45°F for a period of time may bolt or form loose heads. Cover plants if cold weather is expected.
  • Fertilize 2 weeks after transplanting with a balanced (10-10-10) fertilizer.
  • Three weeks later, add a nitrogen-rich fertilizer; cabbage needs nitrogen in the early stages.
  • Practice crop rotation with cabbages to avoid a buildup of soil-borne diseases.

Harvest/Storage

How to Harvest Cabbages

  • Harvest when heads reach desired size and are firm. Mature heads left on the stem may split. Days to maturity is around 70 days for most green cabbage varieties and most produce 1- to 3-pound heads.
  • To harvest, cut each cabbage head at its base with a sharp knife. Remove any yellow leaves (retain loose green leaves; they provide protection in storage) and immediately bring the head indoors or place it in shade. Alternatively, pull up the plant (roots and all) and hang it in a moist cellar that reaches near-freezing temperatures.
  • To get two crops, cut the cabbage head out of the plant, leaving the outer leaves and root in the garden. The plant will send up new heads; pinch off those until only four or so smaller heads remain. Harvest when tennis ball-size (perfect for salads!).
  • After harvesting, remove the entire stem and root system from the soil to prevent disease. Only compost healthy plants; destroy any with maggot infestation.

How to Store Cabbages

  • Cabbage can be stored in the refrigerator for up to two weeks, wrapped lightly in plastic. Make sure it is dry before storing. In proper root cellar conditions, cabbage will keep for up to 3 months. See our article on root cellars.
  • Follow this old-time technique to get the most out of your cabbage crop:
    1. In the fall, harvest the entire cabbage plant—stems, head, and roots—enjoying the head as usual and storing the roots in a root cellar through winter. 
    2. As soon as the ground has thawed in spring, plant the roots outdoors. 
    3. Soon, fresh sprouts will form, which can be eaten alone or added to soups, salads, or a dish of your choice.
    4. These replanted cabbages won’t produce full heads, but they should go to seed by the end of summer, providing next year’s round of cabbage seeds!
    • Note: This can also be done indoors on a windowsill in mid- to late winter; keep roots damp and sprouts should form.

Wit & Wisdom

  • Plant near beans and cucumbers, not near broccoli, cauliflower, strawberries, or tomatoes. Check out our chart of plant companions for an expanded list of friends and foes.

Cooking Notes

If boiling cabbage, drop walnuts (shell on) into the water; they will absorb the cabbage’s unpleasant odor.
