Fertilization

Diluted balanced succulent feed once every 2 months. Discontinue fertilization in autumn and winter when growth slows

Eggshell powder topdressing:Crush dried, rinsed eggshells into fine powder; sprinkle lightly on the soil surface to boost calcium levels and enhance drainage without introducing pests or odors
Pruning
  • Remove dry, dead outer leaves to maintain a tidy rosette appearance
  • Trim spent flowering stalks at the base after blooms fade to conserve the plant's energy for new growth
  • Thin overcrowded offsets to improve airflow and reduce the risk of fungal infections
