Care Guide
Watering
Water regularly to maintain moist soil during active shoot growth in spring
Fertilization
Apply balanced organic fertilizer in early spring to support new culm growth. Avoid high-nitrogen fertilizers that may promote weak culm growth
Composted eggshell powder：Sprinkle finely ground, fully dried eggshell powder around rhizome zones; avoid direct contact with young shoots to prevent burningPruning
- Remove dead, damaged, or diseased culms in late winter to improve airflow and reduce competition
- Thin overcrowded clumps by cutting older culms at ground level to encourage new growth
- Trim lower leaves to expose culms for aesthetic appeal and reduce moisture retention around the base
