Seedling
4-6 weeksTiny green leaves emerge; plant has 2-4 true leaves and is ready to transplant at 4-6 weeks old
Start indoors 4-6 weeks before transplant date. Keep soil consistently moist. Provide bright light and good air circulation to prevent damping off.
Vegetative Growth
3-4 weeksYoung plants develop more leaves and a visible stem; plants establish roots and foliage before head formation begins
Transplant outdoors when 4-6 true leaves are present. Keep well-watered and weed regularly. Apply balanced fertilizer every 2-3 weeks. Mulch around base to retain moisture.
Head Formation
4-6 weeksLeaves begin curling inward and compacting; a visible small head forms at the center, gradually enlarging
Maintain consistent moisture—this is critical for head development. Apply nitrogen-rich fertilizer to support leaf formation. Watch for pests and diseases. Remove any damaged outer leaves.
Heading & Maturation
2-3 weeksHead becomes increasingly dense and compact; outer leaves firm up around the head, developing the characteristic golden-yellow color
Continue regular watering and fertilizing. Monitor for cabbage moths, loopers, and flea beetles. Side-dress with compost if needed. Heads should feel solid when gently squeezed.
Harvest
Ready at 70-85 daysHead reaches full size (typically 3-5 lbs), is firm to the touch, and displays the rich golden-yellow interior and exterior coloring
Harvest when heads are firm and dense. Cut at the base with a sharp knife, leaving outer wrapper leaves. Can be left in field for cool storage or harvested and stored in cool conditions.
