Seedling
1-2 weeksEmergence of first true leaves; seedlings appear delicate with cotyledons followed by characteristic Asian green leaves
Keep soil consistently moist. Provide bright light if starting indoors. Thin seedlings to proper spacing when 2-3 inches tall.
Vegetative Growth
2-4 weeksRapid leaf development; plant builds rosette of leaves with characteristic shapes (depending on variety)
Water regularly, maintain consistent soil moisture. Apply balanced fertilizer every 2-3 weeks. Monitor for pests closely.
Mature Rosette
1-2 weeksFull-sized plant with multiple leaves ready for harvest; tender and flavorful at this stage
Continue regular watering. Harvest outer leaves to encourage more growth, or cut entire plant at base.
Regrowth (after harvest)
2-3 weeks per regrowth cyclePlant regenerates from base if cut above soil line; produces secondary harvests
Keep soil moist and continue fertilizing. Successive harvests are typically smaller.
Bolting
Variable; usually signals end of harvestPlant sends up flowering stalk; leaves become tougher and more bitter
Harvest immediately before extensive bolting. Plant timing to avoid hot weather triggers bolting.

Harvest Tips
Begin harvesting outer leaves when plant reaches 4-6 inches tall, or harvest the entire plant at soil line. Cut in morning for best flavor and texture. Most varieties are ready 30-60 days from planting. Frequent harvesting encourages bushier growth and extends harvest season. For best quality, harvest before bolting (which occurs in hot weather).
