Seedling
3-4 weeksTiny cabbage plants with 2-4 true leaves; delicate and pale green
Keep soil consistently moist, provide bright light to prevent leggy growth, maintain temperatures 60-70°F, thin seedlings to prevent crowding
Vegetative Growth
4-6 weeksPlants develop 6-12 true leaves, establish strong root systems, and begin forming stems; foliage is dark green and waxy
Harden off transplants before planting outdoors, space plants properly, monitor for pests, keep soil evenly moist, fertilize every 3-4 weeks
Head Formation
3-4 weeksInner leaves begin curling inward to form loose heads; outer wrapper leaves protect inner leaves
Ensure adequate nutrients (especially nitrogen and boron), maintain consistent watering to prevent splitting, provide full sun, monitor for cabbage moths and loopers
Head Maturation
2-3 weeksHeads firm up and become dense and compact; outer leaves may yellow slightly; head feels heavy and solid when gently squeezed
Reduce nitrogen fertilizer to prevent excessive leaf growth, maintain even moisture, harvest before frost if growing in fall, protect from extreme heat stress
Harvest-Ready
Harvest window 1-2 weeks; can remain in field longer in cool weatherHeads are solid, firm, and have reached desired size; typically 4-8 inches in diameter depending on variety
Monitor for splitting after heavy rain or inconsistent watering, harvest promptly to prevent quality decline, cut heads at the base with a sharp knife

Harvest Tips
Harvest when heads feel firm and solid when gently squeezed, typically 70-120 days after transplanting. Cut the head at the base with a sharp knife, leaving the stem and outer leaves on the plant. Early-morning harvest yields crisper heads. Green cabbage can be harvested at any size but is best at 4-8 inches in diameter. Store in a cool, humid place (32-40°F, 95% humidity) for 3-6 months.
