Care Guide
light_mode
Light
Full sun to partial shade; 6–8 hours of direct sunlight daily. Light afternoon shade in hot climates prevents bolting. Insufficient light slows growth and reduces vigor.
water_drop
Water
Keep soil evenly moist, providing 1–1.5 inches per week. Water consistently to prevent stress and bolting. Drip irrigation works well. Avoid waterlogging, which causes root issues.
compost
Soil
Rich, well-draining soil with pH 6.0–7.5. Incorporate 2–3 inches of compost or aged manure before planting. Bok choy appreciates fertile soil for optimal growth and tender leaves.
science
Fertiliser
Moderate feeder. Apply balanced fertilizer (10-10-10) every 3–4 weeks, or use compost mulch. Side-dress with nitrogen-rich compost to support leaf and stem development.
thermometer
Temperature
Prefers cool temperatures of 50–70°F (10–21°C). Grows quickly in spring and fall. Heat above 75°F triggers early bolting; cool seasons extend harvest windows.
humidity_percentage
Humidity
Moderate humidity (50–70%) is beneficial. Good air circulation prevents fungal diseases and pest problems. Water early in the day to allow foliage to dry.
