Growth Stages

1

Germination & Seedling

10-14 days

Seeds sprout within 5-10 days. Seedlings develop their first true leaves and appear as tiny plants with 2-4 small leaves.

Keep soil warm (60-70°F) and consistently moist. Thin seedlings to proper spacing once they have 2-3 true leaves. Provide gentle air circulation to prevent damping off.

2

Vegetative Growth

15-25 days

Plant rapidly develops multiple leaves and thick white stalks. Leaves are bright green and tender; plant grows quickly in cool weather.

Water consistently and feed with a balanced or nitrogen-rich fertilizer every 2-3 weeks. Remove any yellowing outer leaves. Mulch around plants to retain moisture and keep soil cool.

3

Baby Harvest Stage

1-3 days (window is narrow)

Plant reaches 3-6 inches tall with 4-8 leaves fully formed. Stalks are crisp and tender, leaves are vibrant green. This is the optimal harvest stage for 'baby' bok choy.

Monitor daily for harvest readiness. Pinch off outer leaves or harvest entire plant by cutting at soil level. Consistent watering prevents tough, bitter leaves.

4

Mature Growth

15-20 days

If left unharvested, plant grows larger with more leaves and thicker stalks, reaching 8-12 inches tall.

Continue watering and fertilizing. Plants may bolt if temperatures exceed 75°F or days become long. Watch for flowering stalk development.

5

Bolting & End of Season

Varies by temperature

Plant flowers and produces seed stalk, leaves become tougher and bitter, plant is no longer palatable.

Remove bolted plants and compost. Plant another crop in fall for autumn harvest. Cool-season crop; bolting signals end of harvest.

Common Pests

  • Use row covers before infestation; pick off caterpillars by hand; spray with Bt (Bacillus thuringiensis) or neem oil; plant in fall when moth activity is lower.

  • Apply row covers immediately after planting; use neem oil or insecticidal soap; plant resistant varieties; keep weeds down; reflective mulch may deter.

  • Spray with strong water jet to dislodge; use insecticidal soap or neem oil; introduce beneficial insects like ladybugs; avoid excess nitrogen.

  • Use yellow sticky traps; spray with neem oil or insecticidal soap; increase air circulation; reflective mulch may help.

  • and

    Hand-pick in early morning; use copper barriers or beer traps; remove plant debris; encourage ground beetles and toads.

Harvest Tips

Harvest baby bok choy when plants are 3-6 inches tall and leaves are tender, typically 30-40 days after sowing. Cut entire plant at soil level with a sharp knife, or pinch off outer leaves to allow the center to continue growing for repeated harvests. Harvest in the morning when plants are crisp and hydrated. Baby bok choy is most tender and mild at this young stage; delay harvesting and leaves become tougher and more peppery. For full-size plants, wait 50-60 days.
