Cabbage Growth Stages: 8 Essential Steps For Faster Harvest

Cabbage Growth Stages: How Fast Does Cabbage Grow?

Cabbage is one of the most rewarding cool-season crops gardeners can grow, offering firm heads packed with nutrition and culinary versatility. Understanding its growth stages—from a humble seed to a hefty harvest—empowers you to maximize yields and troubleshoot issues along the way. Generally, cabbage takes between 60 and 100 days to mature from seed, though this range can vary based on variety and environmental factors. For a quicker start, many gardeners opt to transplant young nursery plants, shaving weeks off the process.

Cabbage Growing Basics

As a member of the Brassica family, the cabbage (Brassica oleracea var. capitata) thrives as a cool-season annual. Successful cabbage growing hinges on timing: sow seeds early enough in spring or late summer so heads mature in cool weather. Here are the essentials for thriving cabbage plants:

• Plant in full sun with at least 6-8 hours of light per day
• Water consistently, aiming for about 1 inch of water weekly
• Use nutrient-rich, well-draining loamy or sandy soil
• Incorporate plenty of organic matter (compost or well-rotted manure)
• Fertilize regularly—two weeks post-transplant, and again a month later
• Watch for pests such as aphids, cabbage worms, loopers, flea beetles, and birds

Cabbage comes in many shapes and hues, from classic green to vibrant purple and crinkly savoy types. Maturity times also vary:

• Early varieties: 60–80 days
• Mid-season varieties: 80–90 days
• Late varieties: 90–110 days

8 Growth Stages of Cabbage Plants

To cultivate robust cabbage, it helps to recognize and nurture each key stage of its development. Here’s an in-depth look at all eight stages, from seeding to mature head formation:

1. Seed Stage

It all begins with small, round seeds. Like most brassicas, cabbage seeds benefit from an early start. Sow them indoors or directly outside, depending on your climate and the growing season. Seeds need moisture, warmth, and air for germination, which usually occurs in 6–10 days under optimal conditions.

2. Germination

Once sown, cabbage seeds absorb water and swell, activating enzymes that trigger sprouting. You’ll spot a slender white root (radicle) breaking through the seed coat, quickly followed by a stem pushing upward. This phase happens quickly, usually within a week after planting.

• Maintain consistent soil moisture for best results
• Keep seed trays or beds warm but not hot (ideal range: 65–75°F)

3. Cotyledon Stage

This is the first visible sign of life above the soil. Cotyledons are the tiny, double-lobed seed leaves that emerge 6–10 days after planting. While they don’t resemble mature cabbage foliage, they are crucial for early photosynthesis.

• Keep seedlings well-lit to prevent legginess
• Soil should remain moist, never soggy

4. Early Vegetative Growth

During this period, seedlings grow their first set of true leaves, which look more like adult cabbage leaves. Plants focus energy on leaf and root expansion, absorbing nutrients from the soil to support rapid growth. The seedling develops a compact rosette of lush, overlapping leaves.

• Strengthen seedlings with gentle airflow or outdoor exposure (hardening off) before transplanting
• Begin light fertilization to fuel growth

5. Vegetative Growth and Rosette Formation

As the plant matures in this stage, leaves grow larger and form a basal rosette. This is a crucial growth window, as leaf production directly impacts the eventual size and quality of the cabbage head. The outer leaves expand horizontally, while inner leaves gradually cup inward—early signs of head formation.

• Apply balanced fertilizer or side-dress with compost or aged manure
• Ensure adequate spacing between plants for airflow and growth

6. Head Development

The hallmark of cabbage, the central head, now begins to take shape. Inner leaves compress tightly as they grow, forming a dense, round head. The outer leaves, meanwhile, protect the developing center and continue gathering energy from the sun.

• Keep soil moisture consistent to avoid splitting or cracking
• Mulch around plants to maintain even soil moisture and suppress weeds

7. Maturation

Heads reach maturity when they feel solid and firm to the touch. At this stage, the plant has channeled most of its energy into the central head. Depending on the variety, this stage occurs 60–110 days after sowing.

• Monitor closely—overmature heads can split, and pests may move in
• Check firmness regularly; a soft head is not ready for harvest

8. Harvest (and Beyond)

When the head is fully formed, firm, and appropriately sized for its variety, it’s time for harvest. Use a sharp knife to cut the stem just below the head, leaving some outer leaves attached to protect during storage. If you leave the lower stem in the ground, small side shoots may sprout, offering bonus baby cabbage heads.

• Harvest promptly to avoid toughness or flavor loss
• Winter and savoy cabbages often improve in flavor after a light frost

Tips for Each Cabbage Stage

• Seed to Seedling: Start seeds indoors 6–8 weeks before your last frost date if spring planting. Use seed-starting mix and keep moist but not soggy.
• Transplanting: Harden off seedlings by gradually exposing them to outdoor conditions over a week. Transplant when plants have 3–4 true leaves.
• Vegetative Growth: Fertilize with an organic, nitrogen-rich formulation. Mulch to protect roots and conserve water.
• Head Formation: Watch for pests like cabbage worms and loopers; cover with row netting or hand-pick when seen.
• Harvest: Don’t delay once heads are firm—overripe cabbage can crack or taste bitter.

Common Cabbage Growing Problems and Solutions

• Pest Issues: Aphids, cabbage worms, loopers, and flea beetles can decimate crops. Use row covers, biological controls, or insecticidal soap.
• Splitting Heads: Often due to irregular watering or delayed harvest. Water evenly and harvest promptly.
• Poor Head Formation: Caused by insufficient nutrition or overcrowding. Side-dress with compost and thin plants for airflow.
• Bitter Flavor: Usually the result of heat stress. Plant so heads mature in cool seasons.
• Diseases: Rotate crops annually to prevent soil-borne diseases like clubroot. Remove and destroy infected plants.

Popular Cabbage Varieties

• Green Ball Cabbage: ‘Golden Acre’, ‘Earliana’, ‘Brunswick’
• Red or Purple Cabbage: ‘Ruby Perfection’, ‘Integro’, ‘Salad Delight’
• Savoy Cabbage: Curly-leafed, tender, and mild; ‘Melissa’, ‘Best-of-all’

Varieties differ in maturation window and head shape. Choose types adapted to your region and the intended harvest season.

Harvest and Storage Tips

• Harvest by cutting below the head with a sharp knife
• Leave the outer wrapper leaves for protection
• Store heads in a cool, humid place (refrigerator or root cellar) for several weeks
• Remove loose or damaged leaves before storage
• For extended storage, try fermenting cabbage into sauerkraut

Pest and Disease Management Strategies

• Use floating row covers to exclude egg-laying insects
• Monitor underside of leaves for cabbage worm eggs
• Handpick caterpillars and destroy them when spotted
• Attract beneficial insects with companion plantings (flowers, herbs)
• Practice annual crop rotation among brassicas to reduce soil-borne issues

Frequently Asked Questions (FAQs)

Q: How long does it take for cabbage to grow from seed to harvest?

A: Depending on variety and conditions, cabbage matures in 60–110 days after seeding.

Q: Why are my cabbage heads not forming?

A: Poor head formation can result from overcrowding, low nutrients, excessive heat, or pest damage. Thin seedlings, enrich soil with compost, and protect from pests.

Q: Can I grow cabbage in containers?

A: Yes! Choose a container at least 12 inches deep and wide per plant, use rich organic soil, and water consistently.

Q: When should I harvest cabbage?

A: Harvest when heads are firm and reach full size for their variety, but before they crack or split. Use a sharp knife to cut at the base.

Q: Which pests should I watch for?

A: Key pests include aphids, cabbage worms, cabbage loopers, flea beetles, and cutworms. Inspect regularly and act quickly to control outbreaks.

Conclusion

Mastering the eight cabbage growth stages—from the first sprouting cotyledons to lush leafy rosettes and finally a crisp, compact head—translates to reliable harvests and garden satisfaction. With the right timing, attention, and care, you’ll find cabbage is a crop worth the effort, offering nutritious heads to enjoy fresh, cooked, or fermented throughout the cool season.
