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.
Best sown Summer and Autumn (cold), July to March (warm), and all year in the tropics. Sow seed 1 cm deep, thinning to 15 cm. Expect germination in 7 – 10 days at 18 deg. C. soil temperature. Sow the seed where the crop is to be grown, watering and feeding generously.
