When to Plant Cabbage Seeds

Cabbage performs best when grown in cool weather, making spring and fall the ideal seasons.

Spring Planting

  • Start seeds indoors 6–8 weeks before last frost

  • Transplant outdoors when nighttime temps stay above 40°F

Fall Planting (Best Flavor & Tightest Heads)

  • Start seeds 10–12 weeks before first frost

  • Transplant outside once seedlings are hardened off

Fall-grown Cabbage often produces sweeter, firmer heads and has fewer pest issues.


How to Start Cabbage Seeds Indoors

1. Choose a High-Quality Seed Starting Mix

Fine, light mixes help seeds germinate quickly and prevent rot.

2. Plant Seeds ¼ Inch Deep

Cover lightly and keep evenly moist.

3. Provide Strong Light

LED grow lights placed 2–3 inches above seedlings prevent leggy growth.

4. Maintain Consistent Temperatures

Germination is best at 65–75°F.

5. Feed Seedlings Lightly

Once true leaves appear, use diluted liquid fertilizer for strong early growth.

6. Harden Off Plants

Introduce seedlings outdoors gradually for 5–7 days before transplant.

Transplanting Cabbage Into the Garden

When seedlings have 4–6 true leaves and the weather is cool and stable, transplant them outdoors.

Spacing

  • 12–18 inches between plants

  • 24–36 inches between rows

Soil Requirements

Cabbage grows best in:

  • Rich, fertile soil

  • Full sun (6–8 hours)

  • pH 6.0–7.0

  • Consistent moisture

Amend soil with compost or aged manure for stronger growth and tighter heads.


How to Grow & Care for Cabbage

Watering

Cabbage requires steady moisture for compact, dense heads.
Avoid letting soil dry out completely.

Fertilizing

Feed plants every 2–3 weeks with:

  • Balanced vegetable fertilizer

  • Compost tea

  • Fish emulsion

  • Organic nitrogen sources

Healthy, nutrient-rich soil leads to better head formation and higher yields.

Mulching

Mulch helps:

  • Retain soil moisture

  • Suppress weeds

  • Keep roots cool

  • Prevent stress and bolting

Pest Prevention

Watch for:

  • Cabbage worms

  • Loopers

  • Flea beetles

  • Aphids

Use row covers early in the season and inspect plants weekly.


Harvesting Cabbage Correctly

Cabbage is ready to harvest when:

  • Heads feel firm and solid

  • Leaves are tightly wrapped

  • The head is fully formed but not splitting

Cut the head cleanly at the base.
Many varieties will produce small side heads after the main harvest, extending your yields.
