Seedling
2-3 weeksEmerge with two small cotyledons (seed leaves) followed by true leaves. Seedlings are tender and susceptible to damping off.
Keep soil consistently moist but not waterlogged. Maintain temps 60-70°F. Thin to prevent crowding. Protect from pests early with row covers.
Vegetative Growth
3-4 weeksRapid leaf development with 8-12 leaves forming a loose rosette before heading begins. Leaves are deeply veined and gradually elongate.
Maintain consistent watering and provide balanced nitrogen fertilizer every 2-3 weeks. Remove damaged outer leaves. Monitor for aphids and flea beetles.
Head Formation
2-3 weeksLeaves begin curving inward and forming a compact, elongated head. Inner leaves become progressively lighter and more tender as they're shielded from sunlight.
Critical stage for water consistency—fluctuating moisture causes heads to split or fail to form properly. Apply mulch to regulate soil moisture and temperature. Continue light fertilization.
Maturation
1-2 weeksHead firms up and becomes fully compact and elongated, typically 8-12 inches tall. Outer wrapper leaves may show slight yellowing. Interior leaves are creamy-white to pale yellow.
Reduce nitrogen fertilization to prevent splitting. Maintain steady watering. Check for maturity by gently pressing the head—should feel firm and dense. Harvest before over-maturity.
Harvest
Variable, peaks at 50-70 daysFully mature, firm heads ready for cutting. Outer leaves are still attached and provide protection during storage.
Cut at soil level in early morning when heads are crisp and hydrated. Leave outer wrapper leaves intact for longer storage. Can be harvested at partial maturity for tender baby heads.

Harvest Tips
Harvest when heads feel firm and dense when gently squeezed, typically 45-70 days from transplanting or 60-80 days from seed. Cut heads at the base with a sharp knife in early morning when hydrated. For continuous harvest, cut outer leaves and allow the central head to continue developing. Heads can be harvested at smaller sizes (baby napa) for tenderness. Store unwashed heads in a plastic bag in the refrigerator for 2-4 weeks. Wong Bok is best eaten fresh within 1-2 weeks for optimal crispness and sweetness.
Fun Facts
- 🌱 Wong Bok napa cabbage was developed in China in the 15th century and literally means 'Chinese cabbage' in Cantonese; it was introduced to Japan and popularized as 'napa' during the Meiji era.
- 🌱 Unlike Western cabbage, napa cabbage is frost-sensitive and bolts (goes to seed) easily in response to long daylight hours and warm temperatures, making it ideally suited to cool-season spring and fall growing.
- 🌱 A single mature Wong Bok head can contain 200+ individual leaves tightly layered together, with the innermost leaves being the most tender and palest in color due to minimal light exposure.
