Seedling
7-10 daysSmall cotyledons emerge with first true leaves appearing within 5-7 days. Plants are delicate with thin stems.
Keep soil moist and provide bright light. Thin seedlings to proper spacing to reduce competition. Protect from extreme temperatures.
Vegetative Growth
20-30 daysRapid leaf and stalk development; multiple dark green leaves expand around the central white stem cluster. Plant reaches 6-8 inches tall.
Maintain consistent moisture and moderate nitrogen fertilization. Mulch around plants to retain moisture and regulate soil temperature. Monitor for pests.
Mature Rosette
10-20 daysFull-sized plant with thick, tender white stalks surrounded by large dark green leaves. Ready for harvest at baby or full maturity.
Continue regular watering. Harvest outer leaves to encourage continued production, or harvest entire head when 8-12 inches tall.
Bolting
5-10 daysFlower stalk emerges from center; leaves become tougher and more bitter. Plant flowers with yellow blooms if left unharvested.
Harvest before or as bolting begins for best quality. Bolting is accelerated by heat, long days, and inconsistent watering.

Harvest Tips
Harvest baby bok choy at 30-45 days (4-6 inches) for tender texture, or wait until full maturity at 45-60 days (8-12 inches). Cut entire heads at soil level with a sharp knife, or harvest outer leaves individually for continued production. Morning harvests yield crispest leaves. Harvest before bolting occurs, especially in hot weather. Bok choy can be harvested multiple times if inner leaves are left intact.
