Seedling (Days 1-14)
2 weeksTiny plants with 2-4 true leaves emerge; very delicate with threadlike stems
Keep soil moist; provide consistent light and warmth (60-70°F). Thin seedlings to proper spacing once 2 inches tall. Protect from strong wind and direct intense heat.
Vegetative Growth (Days 15-35)
3 weeksRapid leaf expansion; plants develop rosette shape with increasingly darker green foliage and thickening stalks
Maintain consistent moisture and coolness; feed with balanced fertilizer every 2-3 weeks. Monitor for pests. Thin crowded plants if needed.
Mature Rosette (Days 36-50+)
2-3 weeksFull-sized plant with dense heads of glossy green leaves on thick white or pale green stalks; plant reaches 8-12 inches tall
Continue regular watering. Increase nitrogen if foliage appears pale. Watch for bolting in heat (flowering, which makes leaves bitter). Harvest outer leaves or entire plant.
Harvest-Ready (Days 45-60)
Variable—harvest when desiredPlants are fully mature with firm heads, crisp stalks, and rich green coloration; ready for immediate use
Begin harvesting immediately to prevent bolting and toughening. Cut outer leaves for continuous harvests, or harvest entire head. Water well before harvesting for maximum crispness.

Harvest Tips
Begin harvesting leaves when plants are 4-6 inches tall (30-40 days) for baby pak choy. For mature plants, cut outer leaves first to encourage continued growth, or harvest entire head at soil level with a sharp knife. Morning harvest after dew dries yields crispest leaves. Can be harvested multiple times by removing outer leaves while allowing center to continue growing. Flavor is mildest and stems most tender before temperatures exceed 75°F.
Fun Facts
