There are several types of chinese cabbage. Chinese cabbage is more closely related to the mustards than to the cabbages. Chinese cabbage prefers cool weather and likes a fertile, well drained, moist soil. Some root problems can be avoided on light soil.
Chinese cabbage can be direct seeded into the garden to avoid transplanting shock.
Bok Choi is spaced 8 to 10 inches apart in rows 12 to 15 inches apart. Thin to 8 to 10 inches 2 to 3 weeks after the plants emerge. Wong Bok is grown in rows 20 to 30 inches apart with the plants 12 to 15 inches apart in the rows. Closer spacings give smaller heads. Early maturing varieties of wong bok have smaller heads so may be planted closer together.
