Cultivation

Succeeds in full sun in a well-drained fertile preferably alkaline soil[7]. Prefers a pH of 5.5 to 7[7]. Tolerates a pH in the range 4.3 to 7.5. Prefers a cool moist reasonably fertile soil[2]. The plant is shallow rooted and intolerant of drought, it needs to be grown in a moist fertile soil for the best quality leaves[5].

Plants are not tremendously cold-hardy, though they will withstand light frosts[8].

Pak choi is widely cultivated, especially in China, for its edible leaves which are produced mainly in the summer and autumn. A fast-growing plant, there are many named varieties and some can be ready in as little as five weeks from sowing the seed[9][5][10]. Forms with green stems tend to stand up better to adverse conditions than white-stemmed forms[5].
