Demand for Asian greens in New Zealand has increased by almost 400% in the past few years, according to Jay Clarke, director of Woodhaven Gardens in Levin. The company has increased its acreage to meet this demand, growing crops such as Shanghai bok choy, wombok, Saigon radish, and coriander. Clarke attributes this increase in demand to New Zealanders trying new foods and expanding their culinary experiences. However, growing Asian greens is challenging due to caterpillar infestations.
