Watering
Drought-tolerant; water deeply but infrequently, allowing the soil to dry completely between waterings to prevent root rot

Care Guide
Watering
Reduce watering frequency; allow the top 15–20 cm of soil to dry fully before rewatering
Fertilization
Apply a diluted balanced organic fertilizer once every 2 months. Avoid high-nitrogen fertilizers, which can reduce flowering and promote excessive foliage growth
Crushed eggshell topdress：Crush dried eggshells into a fine powder and sprinkle lightly over the soil surface to boost calcium levels and improve soil drainage; avoid burying deep to prevent odor buildupPruning
- Prune lightly immediately after flowering to maintain a rounded, compact shape
- Remove dead, damaged, or diseased branches to improve airflow and reduce pest risk
- Thin overcrowded inner growth to encourage new flowering stems for the next season
