Seedling
7-10 daysTiny leaves emerge, plant is 1-2 inches tall with cotyledons visible
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing when 2-3 true leaves appear.
Vegetative Growth
3-4 weeksMultiple leaves develop, stalks thicken, plant becomes bushy, 4-8 inches tall
Maintain consistent moisture and steady nitrogen fertilization. Monitor for flea beetles and other pests. Mulch to retain moisture and regulate soil temperature.
Rosette Formation
2-3 weeksPlant develops characteristic rosette shape with prominent white or pale green stalks clustered at base, 8-12 inches tall
Continue regular watering and light feeding. Ensure adequate spacing for air circulation. Watch for early bolting signs in warm weather.
Harvest Maturity
Variable, ready to harvestPlant reaches full size, 8-14 inches tall depending on variety, stalks are tender and crisp, leaves are vibrant green
Begin harvesting outer leaves or harvest entire plant. Harvest before bolting occurs, particularly in warm weather. Early morning harvest yields crispest leaves.
Bolting
Occurs 2-3 weeks after maturity if conditions favor boltingPlant sends up flowering stalk, leaves become bitter and tougher, plant elongates dramatically
Harvest immediately if not yet done. Remove bolting plants to prevent self-seeding. Bolting is triggered by heat and long day length.

Harvest Tips
Harvest when plants are 6-8 inches tall for best tenderness. Cut outer leaves individually for continuous harvest, or cut entire plant 1 inch above soil line for regrowth. Harvest in early morning when stalks are crisp and cool. For baby bok choy, harvest at 3-4 inches tall. Plants are most tender before bolting; harvest immediately if flower buds begin to form. Can be harvested as microgreens at 2 weeks for tender shoots.
