Start by sowing the seeds one to two inches deep, with a space of three to four inches between plants. The use of a low tunnel for the first month of growing (Until June 20th) will help in the production of these lovely tender beans. The Chinese Vigna can tolerate acidic soils and will require full sun. Water them often so that they don’t wilt in the sun. Due to the nature of a vine, support, such as a trellis, will be needed. Pods grow long and slightly heavy, so they will need strong support. The pods take two to three months to reach maturity, at which point they should be anywhere from 60-80 cm long. you will want to start picking them when they are 20-25 cm long. Once pods begin to reach this size, they should be harvested each day to encourage production on the vine. Vines need a trellis and reach 3 meters high.
