Growth Stages

Seedling

7-14 days

Cotyledons emerge within 5-10 days, followed by the first true leaves with the characteristic feathery mizuna appearance

Keep soil warm (65-70°F) and moist. Provide bright light to prevent leggy seedlings. Thin to proper spacing once first true leaves appear.

Vegetative Growth

10-20 days

Plant develops multiple feathery leaves and compact rosette form. Leaves are tender, bright green, and deeply cut

Water consistently, maintain cool temperatures (55-70°F), and apply balanced fertilizer every 2 weeks. Protect from strong wind. Monitor for flea beetles.

Leaf Development

10-15 days

Plant reaches near-mature size with abundant feathery foliage and thickened stem bases characteristic of bok choy

Continue regular watering and feeding. Harvest outer leaves if desired for continuous production. Keep soil consistently moist.

Maturity

Ready to harvest; continue harvesting until bolting or declining quality

Plant reaches full size (6-10 inches tall) with dense foliage and tender, flavorful leaves and stems ready for harvest

Harvest promptly to encourage continued production. Cool temperatures extend quality. Cut plants at soil level or harvest individual outer leaves.

Harvest Tips

Harvest in the morning after dew dries for best texture and flavor. Cut individual outer leaves with a knife when 2-4 inches long, allowing inner leaves to continue growing (cut-and-come-again method), or harvest entire plant at soil level when 6-10 inches tall. For baby greens, harvest at 20-30 days. Cooler temperatures improve flavor and texture. Continuous harvesting can extend productivity for 4-6 weeks. Most tender and flavorful before any flowering begins.
