Edible soybean, called Edamame in Japan and Mao Dou in China, is grown mainly to harvest the young green-shelled beans for vegetable uses, but not for the matured soybean crops. Plants grow best in warm climates but poorly in cold conditions. Soybean seed germination is relatively sensitive to water content in soil. Seeds can be easily rotted and fail to germinate if overwatered or soaked. Keep soil only moist but not soaked during the germinating period. Edible soybean produces clusters of pods with green beans. Pick the pods when they are plump but still green. All pods on the plants are harvested at the same time. It is suggested to start seedings at several different times, so you can have continuous harvests of Edamame beans.
