Watering

Water when the top 5 cm of soil is fully dry; reduce watering during extreme heat if leaves show signs of wilting

Fertilization

Apply diluted succulent fertilizer once monthly. Use a low-nitrogen fertilizer to promote healthy leaf growth without encouraging leggy stems

Eggshell powder topdress:Crush thoroughly dried eggshells into a fine powder; dust lightly on the soil surface, keeping it 2 cm away from the stem to avoid rot
Pruning

  • Trim spent flower stalks after blooming to redirect energy back to leaf growth
  • Pinch back stem tips in early spring to encourage bushier, compact growth
