Keep soil slightly moist but not waterlogged; allow topsoil to dry between waterings

Fertilization

Diluted succulent fertilizer applied once monthly. Avoid over-fertilizing, as excess nutrients can cause leggy growth and reduced leaf vibrancy

Eggshell powder topdressing:Crush fully dried eggshells into fine powder; sprinkle a thin layer on soil surface to add calcium without burning delicate roots
Pruning
  • Remove yellowing or damaged leaflets at the base to maintain a tidy clump
  • Trim spent flower stems after blooming to redirect energy to new foliage growth
  • Divide overcrowded clumps in early spring to propagate and refresh soil
