Generally, the seeds germinate one week after sowing, and the seedlings (about 6-8 cm in height) of three weeks old can be planted in the field or directly seeded. For cutting propagation, semi mature stems with a length of 8-10 cm are inserted into the seedbed and transplanted to the field after growing roots (about 15 days); mature stems with a length of 15-20 cm can also be used for direct cutting and planting. The spacing between plants and rows is generally 25-30 cm × 30-40 cm or 20-35 cm × 20-30 cm, which is related to harvesting method and cultivation duration.
