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. Small plants may be harvested to thin the crop. They will bolt (go to flower) if not harvested quickly.
