Care Guide

Watering

Water when top 10–15 cm of soil is dry; allow excess water to drain fully from the pot

Fertilization

Diluted succulent fertilizer once every 4 weeks. Cease fertilization in winter when the plant is dormant to avoid root burn

Eggshell powder top-dressing:Crush fully dried eggshells into fine powder; sprinkle lightly on the soil surface, avoiding direct contact with the caudex to prevent irritation
Pruning
  • Prune overgrown stems in early spring to encourage bushier growth and more flower production
  • Remove dead or yellowing leaves and spent flower heads to maintain plant health and appearance
  • Trim back leggy growth to preserve a compact, balanced form; use clean, sharp shears to minimize infection risk
