Seedling
10-14 daysSmall cotyledons emerge, followed by 2-4 true leaves with characteristic waxy coating
Keep soil consistently moist; thin seedlings to strongest plant if direct seeding. Provide bright light to prevent legginess. Protect from pests with row covers.
Vegetative Growth
20-30 daysPlant develops 8-12 leaves; foliage expands rapidly with pale green color and prominent veining
Begin fertilizing with balanced or nitrogen-rich fertilizer every 2-3 weeks. Monitor for insect pests. Maintain consistent soil moisture. Thin to final spacing if needed.
Head Formation
15-25 daysInner leaves begin to curl inward and overlap, forming a compact cylindrical head; color lightens to pale yellow-green
Reduce nitrogen to encourage head tightness. Water consistently to prevent head splitting. Support with loose ties if needed in windy conditions. Stop heavy fertilizing.
Mature Head
10-14 days before harvest window closesHead becomes dense and firm with tightly wrapped pale, tender leaves; head reaches 6-10 inches tall and 3-5 inches diameter
Check maturity by gentle squeezing—head should feel firm but yield slightly to pressure. Ready to harvest when outer wrapper leaves still show some green. Continue watering if extended harvest is planned.
Harvest/Post-Maturity
Variable based on harvest timingHead can be harvested when mature; if left in field, outer leaves may yellow and inner leaves can become tough or bolt
Harvest promptly to maximize quality and flavor. Cut at soil line with sharp knife. Store at 32-40°F with high humidity (90-95%) for extended shelf life (2-4 weeks).

Harvest Tips
Otohime is ready to harvest 45-65 days after transplanting. Harvest when the head is firm and compact with a slight give when gently squeezed; cut at the soil line with a sharp knife. Early morning harvest provides maximum crispness. Can harvest the whole plant or remove outer leaves for extended harvest. For storage, chill immediately and maintain 90-95% humidity at 32-40°F for 2-4 weeks of shelf life.
Fun Facts
- 🌱 Otohime means 'princess' in Japanese, a reference to the delicate, tender nature of its leaves and its premium quality among napa cabbage varieties.
- 🌱 Otohime is significantly faster-maturing than standard napa cabbage (45-65 days vs. 70-90 days), making it ideal for succession planting in short growing seasons or containers.
- 🌱 Napa cabbage was bred from turnips (Brassica rapa) in China during the 15th century and didn't reach Japan until the early 20th century, yet Japanese breeders created some of the most refined cultivars like Otohime.
