Care Guide
Watering
Keep soil consistently moist; avoid drying out completely during active growth
Fertilization
Diluted balanced liquid feed once every 4 weeks. Use low-nitrogen feed to prioritize bloom production over lush foliage
Eggshell powder topdressing：Crush dried eggshells to fine powder; sprinkle lightly on soil surface; water in slowly to release calcium and maintain alkaline pHPruning
- Remove spent flower stems after blooming to redirect energy to rosette growth
- Trim brown or damaged leaf tips to preserve neat rosette appearance
- Thin overcrowded rosettes in early spring to improve airflow and reduce disease risk
