Watering

Maintain consistent soil moisture; apply organic mulch to retain water and regulate soil temperature

Fertilization

Apply diluted organic feed once monthly. Use nitrogen-rich, low-phosphorus organic feed to support frond growth without disrupting soil acidity

Composted spent tea leaves：Mix fully composted spent tea leaves into topsoil; avoid raw leaves to prevent mold growth and odor issues

Pruning

Remove brown, dead fronds at the base to improve airflow and maintain a neat clump
Trim damaged frond tips to prevent browning from spreading
