Fertilization

Diluted cactus fertilizer once every 2 months. Use only diluted, low-nitrogen fertilizer to prevent leaf burn

Eggshell powder topdressing:Crush fully dried eggshells into fine powder; sprinkle a thin layer on the soil surface to add calcium without damaging sensitive roots
Pruning
  • Remove dry, dead leaf pairs to maintain a tidy rosette appearance
  • Trim overgrown offsets in early spring to control clump size and encourage new growth
  • Snip spent flower stalks after blooming to conserve the plant's energy
