Care Guide
Watering
Water when top 2–3 cm of soil is dry; increase frequency slightly during heatwaves
Fertilization
Diluted low-nitrogen feed once every 4 weeks. Use succulent-specific diluted feed to avoid promoting leggy, weak growth
Eggshell powder topdressing：Crush clean, dried eggshells into fine powder; sprinkle lightly on soil surface every 3 months to boost soil structure without burning rootsPruning
- Trim back leggy stems in early spring to encourage compact, bushy growth
- Deadhead spent flower clusters to maintain a tidy appearance and redirect energy to foliage growth
- Remove yellowed or damaged leaves as needed to prevent pest and fungal buildup
