2. Growing Cabbage from Seed

Learning how to grow cabbage from seed is an essential skill for any gardener. Cabbage seeds can be easily found in garden centers or online retailers. When choosing seeds, ensure they are of high quality and from a reputable supplier for the best results.

Seed Germination

Fill a seed tray or small pots with a well-draining, seed-starting mix to start your cabbage seeds. Sow the seeds about 1/4 inch deep and cover them lightly with soil. Mist the soil with water to moisten it, and then cover the tray or pots with plastic wrap to retain moisture.

Place the tray or pots in a location with a consistent temperature of 65-75°F (18-24°C) and indirect sunlight. The seeds should start germinating in 5-10 days. After germination, remove the plastic wrap and move the seedlings to a sunny spot.

Hardening Off

Cabbage seedlings need to be hardened off before transplanting outdoors. This process involves gradually exposing them to outdoor conditions to reduce transplant shock. Begin hardening off your seedlings about two weeks before your intended planting date. Place the seedlings outdoors in a sheltered location for a few hours each day, gradually increasing the time and exposure to sunlight.

3. Planting Cabbage for Success

After hardening off your seedlings, it’s time to transplant them into the garden or larger containers. Follow these steps on how to plant cabbage for the best results.

When to Plant

Cabbage can be planted in spring or fall, depending on your climate and growing variety. Transplant your seedlings outdoors 2-3 weeks before the last frost date for a spring crop or 6-8 weeks before the first frost date for a fall crop.

Site Selection

Choose a location in your garden that receives full sun to partial shade. Cabbage grows best in well-drained, loamy soil with a pH between 6.0 and 7.0. If you’re growing cabbage in containers, ensure the pots have drainage holes and use a well-draining potting mix.

Plant Spacing

When transplanting cabbage seedlings, space them about 18-24 inches apart in rows, with rows spaced 24-36 inches apart. For container-grown cabbage, plant one seedling per pot that’s at least 12 inches in diameter and 12 inches deep.

Watering

Water the newly transplanted seedlings thoroughly to help them establish themselves in their new environment. Keep the soil consistently moist but not waterlogged. Cabbage plants have a shallow root system, so watering regularly is essential, especially during dry spells.

4. Caring for Your Cabbage Plants

Learning how to care for cabbage is crucial for a successful harvest. Here are some essential tips to help your cabbage plants thrive:

Fertilizing

Cabbage is a heavy feeder and requires regular fertilization to produce large, healthy heads. Apply a balanced, slow-release fertilizer at planting time and once more during the growing season. Alternatively, use a liquid organic fertilizer for container-grown cabbage every 4-6 weeks.

Mulching

To help conserve moisture, regulate soil temperature, and suppress weeds, apply a 2-inch layer of organic mulch around the base of your cabbage plants. Mulch materials can include shredded leaves, grass clippings, or straw.

Thinning

If your cabbage plants become too crowded, thin them out by gently pulling up the excess seedlings. This will help improve air circulation and reduce the risk of diseases.

Rotating Crops for a Healthier Garden

In addition to companion planting, practicing crop rotation can help maintain a healthy garden. Crop rotation involves changing the location of plant families in your garden each year, reducing the build-up of pests and diseases specific to certain plants. As a general rule, avoid planting cabbage or other brassicas in the same spot for at least three years.

Pest and Disease Control

Cabbage is susceptible to various pests and diseases, such as cabbage worms, aphids, and clubroot. Check your plants regularly for signs of these issues and treat them accordingly. For example, use Bt (Bacillus thuringiensis) to control cabbage worms or apply insecticidal soap or neem oil to manage aphids. To minimize the risk of diseases, ensure proper plant spacing, practice crop rotation, and avoid overhead watering.

  1. Cabbage Worms and Loopers: These caterpillars chew on cabbage leaves, leaving large holes. Control them by handpicking, using floating row covers, or applying Bacillus thuringiensis (Bt), an organic pesticide.
  2. Aphids: These tiny pests suck plant sap, causing leaves to curl and stunt growth. Control aphids by releasing beneficial insects like ladybugs, spraying insecticidal soap, or using a strong water spray to dislodge them.
  3. Clubroot: This soil-borne disease causes swollen, distorted roots and stunted growth. Prevent clubroot by maintaining a soil pH of 7.0 or higher, practicing crop rotation, and removing infected plants immediately.
  4. Black Rot: A bacterial disease, black rot causes the yellowing and wilting of leaves, eventually turning them black. To prevent black rot, practice crop rotation, use disease-free seeds and transplants, and avoid overhead watering.
  5. Downy Mildew: This fungal disease appears as yellow patches on the upper leaf surface and a white, fuzzy growth on the lower surface. Improve air circulation, avoid overhead watering, and use organic fungicides to prevent downy mildew.

By staying proactive and implementing effective pest and disease management techniques, you can protect your cabbage plants from these common problems. Regularly monitor your plants for signs of infestation or disease and apply the appropriate treatments as needed. You’ll enjoy a bountiful harvest of healthy, homegrown cabbage with proper care.

5. Harvesting Cabbage: Tips and Tricks

Knowing how to harvest cabbage is essential for enjoying the freshest, most delicious produce. Follow these tips for the best harvest:

When to Harvest

Cabbage heads can be harvested when they reach the desired size and feel firm when squeezed gently. The size will vary depending on your growing variety, but most types are ready to harvest 70-100 days after transplanting.

Harvesting Method

To harvest a cabbage head, simply use a sharp knife to cut the stem at the base of the head. Leave a few outer leaves attached to protect the head during storage.

Storing Cabbage

Cabbage can be stored in a cool, dark place, such as a refrigerator or root cellar, for several weeks. Keep the heads in a perforated plastic bag or wrap them loosely in a damp cloth to maintain freshness.

6. How Long Does It Take Cabbage to Grow?

One common question among gardeners is, “how long does it take cabbage to grow?” The answer depends on the variety and growing conditions. Most cabbage varieties take between 70 and 100 days from transplanting to reach maturity. Early varieties may mature in as little as 50 days, while late-season varieties can take up to 120 days.

By following these guidelines on how to grow cabbage, you’ll be well on your way to enjoying fresh, homegrown cabbage in your favourite dishes. Happy gardening!

7. Companion Planting for Cabbage
