Unlike many traditional European and New World vegetables, most Asian vegetables mature very quickly, and once ready to harvest must be picked within a day or so. Small regular sowings are required. Pak Choi (Bok Choy) and Chinese Cabbage (Wong Bok) are best sown in summer and autumn in cold areas, July to March in warm areas and all year in tropics. Sow the seed where the crop is to be grown, watering and feeding generously.
Sow seed where plants are to mature, 1 cm deep, in spring and summer (cold), July to March (warm) and all year in the tropics. Thin to 30 cm apart. Germinates in 10 to 12 days at 21 deg.C. Keep well watered.
