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 1 cm deep, thinning to 10 to 40 cm apart, depending on the need for small or larger plants. Germinates in around 1 week. In warm soil.
