Cool season crop

How to grow bok choy
Bok choy can be seeded directly in the ground, but starting the seeds in little pots, 2 to 4 weeks before it’s time to put them in the ground, seems to have a higher success rate in our area. Bok choy needs loose, rich soil. This makes it a good candidate for raised beds and containers, where you have more control over soil structure. Seeds should be planted 1/4 to 1/2 inch deep, and they should germinate in 7 to 10 days. After seedlings are 4 inches tall, they can be very gently transplanted to their garden location. Place seedlings 6 to 10 inches apart. Plants take only 45 to 50 days to reach maturity, so this is a pretty rewarding crop.
