Care Guide

Watering

Water thoroughly when soil is fully dry; reduce frequency during extreme heatwaves to prevent sunscald

Fertilization

Diluted succulent fertilizer once every 2 months. Use a low-nitrogen, phosphorus-rich fertilizer to support caudex growth

Eggshell powder topdressing:Crush dried, rinsed eggshells into fine powder; dust lightly on the soil surface to add calcium without altering soil pH; avoid overapplication to prevent nutrient buildup
Pruning
  • Remove dead or yellowing leaves during active growth to improve airflow
  • Trim leggy stems in early spring to maintain a compact, balanced form
  • Avoid cutting into the main caudex unless removing damaged or rotting tissue
  • Repot only when rootbound; handle the fragile caudex carefully to prevent cracking
