In the second year, the seeds germinated from May to June and broke their shells, and from July to August, they germinated and grew a true leaf, which could be transplanted.

Tillering propagation

Cutting tillers on the trunk and planting in sandy loam with row spacing of 20-30cm, plant spacing of 10-15cm, covering soil of 6-8cm, shade, easy to survive under semi-shade condition.
