• Soil: Cabbage prefers well-drained, fertile soil with a pH between 6.0 and 7.5. Amend the soil with compost or well-rotted manure to improve fertility.

• Sun: Full sun is ideal, but cabbage can tolerate partial shade, especially in hotter climates.

• Watering: Keep the soil consistently moist but not waterlogged. Mulching helps retain soil moisture and regulate temperature.

• Spacing: Plant seedlings 24 inches apart in rows spaced & 9-16 inches apart to allow adequate air circulation and room for growth.

• Fertilization:
  N-P-K Ratio: Cabbage benefits from a balanced fertilizer with a higher nitrogen content to support leafy growth, such as 10-10-10 or 12-12-12.

  When to Add:

  • Before Planting: Apply the balanced fertilizer to the soil before planting seeds or transplants to promote strong initial growth.

  • Mid-Growing Season: Reapply the fertilizer about three to four weeks after planting and again when the heads start to form to support continued growth and head development.

  Application Tips:

  • Follow the directions on the fertilizer package to avoid over-fertilization.

  • Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

  Additional Tips:

  • Cabbage grows best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

  • Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

  • Ensure that cabbage receives consistent moisture, especially during head formation, to prevent stress and promote even growth.

• Harvest: Cabbage is ready to harvest when the heads are firm and solid, usually 70-110 days after planting. Cut the head off at the base with a sharp knife, leaving the outer leaves and root in place for potential secondary growth.
