Growing Bok Choy in Zone 8B

Bok Choy is a crisp, fast-growing Asian green that thrives in cool weather. Baby bok choy varieties can be ready in just 30 days, making it ideal for spring and fall gaps in the garden.

Zone 8B enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Sow indoors 4 weeks before last frost or direct sow in early spring
• Prefers soil temperatures between 45-75°F — bolts quickly in heat
• Space standard varieties 6-9 inches apart; baby types can be closer
• Harvest whole heads when compact, or cut outer leaves for partial harvest
• Fall sowing is often more successful — cooler temps prevent bolting

Companion Planting

Good companions: beets, onions, celery, aromatic herbs

Avoid planting near: strawberries, pole beans, tomatoes
