The herb is suitable for planting in temperate zone. It begins to turn green in the northern area in mid-April in April. The plant grows to about 1 meter in late May and the plant height is more than 2 meters in late June.

Sowing time can choose spring broadcast, summer broadcast or autumn broadcast. Before sowing, the seeds will be sunned for 2 to 3 hours, soaked in warm water at 30°C to 35°C for 8 to 10 hours, and sowed directly after sowing.

The fresh grass can be chopped or slurried and then directly mixed into the feed. Silage can also be performed. Urea urea 10 kg after each castration.
