The Basics
When to plant
- February to April and September to October.
- Bok choy is prone to bolting if planted too early or during warm weather.
Care overview
- Select a sunny spot with well-amended, fertile soil.
- Sow the seeds 1/4 to 1/2 inch deep.
- When plants are about 4 inches tall, thin to 6 to 8 inches apart.
Harvest window
- Harvest about a month after sowing, when they are about 1 foot tall.
- Entire plants may be harvested to thin the crop and give remaining plants more room.
- Bok choy will bolt (go to flower) quickly if not harvested.
