Diluted balanced liquid feed once every 6 weeks. Use a half-strength, low-nitrogen feed to support compact growth without damaging foliage
Composted eggshell powder：Sprinkle a thin layer on soil surface; avoid direct contact with foliage to prevent leaf burn and wash lightly into soil with waterPruning
- Trim back brown or dead stems at the base to maintain compact, tidy growth
- Thin overcrowded mats to improve airflow and allow light to reach inner foliage
