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.
