Native to Asia, bok choi is a member of the cabbage family. The vegetable is grown from seed in spring and fall for its tender leaves and crunchy stalks, both of which have a light cabbage-like flavor. Bok choi grows more quickly than round-headed cabbage. Popular varieties include Bok Choi and Joi Choi.
Bok choi likes a sunny spot with rich, well-drained soil. Work some compost or all-purpose fertilizer into the bed with a garden fork to give the plants an early boost. Form rows 1/2" deep and 10" apart.
After the seedlings sprout, thin to just one plant every 12" to 15". Keep the young plants moist while they are getting established by watering in the morning. Handpick any slugs that appear on or near the plants and drop them into a jar of soapy water.
