Diluted succulent fertilizer once every 2 months. Use low-nitrogen fertilizer to promote flower production rather than foliage growth

Eggshell powder top dressing:Crush clean, fully dried eggshells into fine powder; sprinkle lightly on soil surface to boost calcium levels without burning succulent roots
Pruning

  • Trim leggy stems in early spring to promote bushier new growth
  • Remove yellowing or damaged leaves to improve airflow and reduce pest risk
