How to Plant and Grow Cabbage: A Fall and Spring Staple Crop

Brassica oleracea var. capitata

Cabbage is one of my all-time favorite cool weather crops to grow in my garden.

What is not to love about cabbage? Vibrantly colored, packed with nutrients, and quick to mature, these crunchy garden giants are a timeless classic that never seem to get old.

Cultivation and History

Cabbage is a cultivar of Brassica oleracea and is the same species but a different cultivar of other popular cole crops such as cauliflower, broccoli, and kale.

Heading cabbage  has been a part of the human culinary story for a very long time and was likely domesticated sometime around 1000 BC where it was developed from wild cabbage (Brassica oleracea var. oleracea) which is found along the limestone cliffs of western Europe.

Cabbages became a significant part of the European diet by the middle ages. In Rome, it was a highly regarded vegetable considered something of an indulgence and was often used medicinally.

Around the same time, the Chinese and other Asian peoples developed their own versions from related brassic species which evolved into the Nappa cabage (Brassica rapa subsp. pekinensis) as well as bok choy (Brassica rapa subsp. chinensis).  Later they developed their own Brassica oleracea cultivar called Gai lan or Chinese brocolli (Brassica oleracea var. alboglabra).

The vegetable came to the Americas by sea in the 1500s. It had become a staple on sea voyages because it was easy to preserve, and its high concentration of vitamin C helped prevent scurvy on long journeys.  Sauerkraut was used to prevent gangrene and treat wounds.

Later, other cultivars of Brassica oleracea were developed into the red cabbage (Brassica oleracea var. capitata f. rubra) and savoy (Brassica oleracea var. capitata f. sabauda).

These days, cabbages are a mainstay in culinary traditions around the globe. From sauerkraut, to coleslaw, cabbage rolls, and golabki, a Polish dish made with boiled cabbage leaves filled with minced beef or pork, onions, and rice, the variety of ways humans have devised to prepare and enjoy this staple crop are impressive.

This plant may look simple, but it has so much to offer! It is a no brainer in the garden, and luckily, it is a cinch to grow.

Propagation

From Seedlings/Transplanting

Perhaps best grown from seedlings, start plants early in spring, about 8 to 10 weeks before the last expected frost, so you can harvest before the summer gets too hot.

Transplant into the garden when plants are 3 to 4 inches tall, or 2 to 4 weeks before last frost, leaving 12 to 18 inches of space between each plant.

Don’t forget to harden off plants before transplanting!

For fall plantings, start seedlings in summer about 12 to 14 weeks before the first expected frost, transplanting into the garden when plants have reached 4 to 6 weeks of age. Fall is a great time to grow cabbage, as these cold tolerant crops tend to improve in flavor after exposure to light frosts.

Cabbage should be planted in full sun, in well-draining soil amended with organic material.

From Seed

Seeds can also be sowed directly as soon as the soil can be worked in the spring.

It can also be seeded repeatedly throughout the season for a continual harvest, though plants may need additional care and protection to survive the heat of summer. Check out our guide here to learn more about succession planting techniques.

How to Grow

Since cabbage are heavy feeders, it is important to incorporate plenty of aged manure or compost into the garden bed prior to planting. Using a garden fork, mix in a few inches of compost or aged manure and water thoroughly before setting out seeds or transplants.

You can also try adding a nitrogen rich amendment such as blood meal to the soil.

It is also important to ensure an appropriate pH range, 6.5-6.8 is ideal. Keeping the soil pH above 6.8 will help prevent clubroot, a common cabbage disease that thrives in acidic soil.

Continue to provide nitrogen boosts to growing plants, especially as heads are beginning to form. Side dress with compost every few weeks, use a liquid organic fertilizer, or apply a homemade liquid fertilizer such as comfrey tea, which is made from soaking comfrey leaves in water for a few days to draw out nutrients.

Don’t Let Them Split

One thing to watch for when growing cabbage is the splitting of heads, which can be caused by heavy rain, often following a bout of dry weather. Splitting happens when the roots absorb too much water at one time and leaf tissue expands quickly. Unable to handle the pressure caused by a sudden increase in water, firm heads are split apart.

Splitting can also be caused by over fertilization of plants close to the end of the growing season.

To prevent splitting, keep plants well-watered. Be sure that the soil stays consistently moist, especially when harvest time is approaching.

Applying a thick mulch around the base of each plant will help regulate soil moisture.

As an added benefit, heavy mulching will also help build soil, prevent nutrient leaching, and help keep plants cool in the heat of summer. Mulching can also be use to protect plants in the late fall and winter.

Root pruning is a technique that can help reduce the amount of moisture plants can absorb, preventing splitting. Prior to an expected heavy rainfall, twist plants gently or cut off a few roots using a sharp knife.

It is also a good idea to stop feeding plants once heads have started to firm up.

Growing Tips

Use shade covers in the heat of summer to keep young plants cool.

Use season extension tools such as row covers to get an early start in spring and/or keep plants growing later into the fall.

Always rotate crops to retain soil fertility and reduce risk of disease.

Cabbage does well when planted near aromatic herbs, which can help repel unwanted pests and improve the flavor of heads. Try planting near sage or rosemary to help deter cabbage moths.

Don’t plant cabbage near other brassicas, they will attract the same pests and diseases.

Avoid planting near strawberries, which can inhibit the growth of cabbage family plants. Similarly, planting near tomatoes can harm growth of tomato plants.

Managing Pests and Disease

There are a number of common pests and diseases that can affect cabbage plants. The following are some common problems to watch out for:

Pests

Cabbage Loopers

These very common and sneaky little pests can appear at any time during the growing season and can quickly munch their way through the leaves, leaving plants damaged and weak.

Because the caterpillars are green, they blend in easily with the plant and can be hard to see. The bigger they grow, the more damage they cause.

One larva can eat three times their body weight in one day!

Adults are gray-brown moths, which deposit small green eggs on plants that hatch as destructive larvae in only a few days. You can also look for small silky cocoons on stems or undersides of leaves.

Handpick loopers whenever you spot them.

Plant aromatic herbs that attract beneficial insect predators.

Floating row covers can help keep moths from landing on plants and laying eggs

Sprinkle food-grade diatomaceous earth on plants that are showing signs of infestation.

Make a homemade spray with garlic, cayenne pepper, and biodegradable dish soap and apply to the underside of leaves.

Flea Beetles

Flea beetles are small jumping insects that chew small holes in leaves. They overwinter in the soil and become active in spring when foliage begins to appear. Look for tiny white eggs around the base of plants or in the soil.

If an infestation becomes severe, they can destroy entire plants. They tend to feed on hot, sunny days.

Flea beetles can also transmit diseases to plants, so it is doubly important to keep infestations under control.

Floating row covers can be very effective when placed over young seedlings.

Diatomaceous earth sprinkled on plants can also kill flea beetles.

Neem oil, which is approved for organic use can also be sprayed on plants to kill beetles in all life stages.

Root Maggots

Root maggots are white legless critters that lay eggs at the base of young plants. The adult tiny grey flies lay eggs around the base of plants in the spring. The maggots feed underground on roots, causing rotting, and potentially plant death. Wilting leaves with occasional yellow or blue foliage can be signs of damage.

Tunnels created in roots by maggots can also harbor diseases such as black rot.

Cover with floating row covers as soon as seeds are sown or transplant sets in to reduce the risk of problems.

You can also apply paper or cardboard rings around the base of transplants to prevent flies from laying eggs around the stem.

Sticky traps placed around the garden can be effective traps for cabbage flies.

Practice crop rotation to reduce the risk of continued infestation.

Disease

Clubroot

This soil borne fungus can infect most brassicas including cabbage. It infects plants through root hairs, causing roots to become deformed and rot, and making nutrient and water absorption difficult.

Common signs include wilting in heat and yellowing or browning of leaves.

Spores can spread by water, wind, or tools, and can live in the soil for up to 10 years. Though disease can appear in many conditions, too much moisture and low soil pH may increase risk of infection.

There is not much you can do after plants have become infected, other than to remove infected plants and wash gardening tools after use.

Prevention is key. Choose resistant varieties, rotate crops, and apply lime to raise soil pH.

Blackleg

Another common brassica infecting fungus, this disease causes dark spots on stems and leaves. It can overwinter in soil, on plant debris, and live in seeds. It is common in warm and wet conditions but can appear at any time.

Avoid planting infected seeds, remove infected plants, and remove and destroy crop debris after harvest.

Black Rot

This bacterial disease that turns leaf veins dark and produces a foul smell. The pathogen can spread throughout the plant through the vascular system, and eventually cause leaves to wilt and die.

It is common in wet and warm conditions, and especially thrives in overcrowded garden beds.

Plant crops in a well-draining area to reduce risk. Practice crop rotation, avoid overwatering, and remove infected plants.

In general, the best practice is prevention. Choose disease resistant varities, rotate crops regularly, and remove all parts of cabbage plants from the garden after harvest to prevent diseases and pests from lingering in the soil.

Harvesting

Time to harvest can vary with variety and can range anywhere from 2 to 5 months from seeding.

Harvest cabbages when the heads are large and firm. Leave the wide outer leaves and cut the head out of the center with a sharp knife.

A male holds a cabbage head in his hands that he has just harvested from the field in the background. His other hand holds a knife used to cut the head off the stalk.

Move harvested plants into a shady location immediately or bring inside to avoid wilting.

It may be possible to get a second harvest of an early variety. If you leave the outer leaves and roots intact when doing the initial harvest, the plant will send up several new heads. Pull some off, leaving a few smaller ones to harvest when they are about the size of a tennis ball.

Once you are finished harvesting, remove the entire plant to reduce the risk of disease. Compost healthy plants but destroy those that have become diseased or infested.

Preserving

When storing, keep all leaves on the heads to protect the inner layers and retain moisture and do not wash until ready to use. Cabbage should be stored in a cold, moist location, about 32-40°F.

In the refrigerator, a head can last from 3 weeks to 2 months. Store in plastic bags to retain moisture.

To store in the root cellar, place heads in rows with space between them, hang from string off the ceiling, or store individually on the floor wrapped in newspaper. stored in this way, cabbages can keep for up to 4 months.

Tip: if you harvest the full plant, store roots in root cellar through the winter, and replant them in spring after a thaw. they will produce small edible sprouts, and eventually go to seed which can be saved for the following years crop.

Heads can be chunked up or shredded and be frozen, or of course, my favorite, fermented into sauerkraut!
