Care Guide

Watering

Fertilization

Dried eggshell powder topdress:Crush clean, fully dried eggshells into a fine powder; sprinkle lightly on the soil surface, avoiding direct contact with stems to prevent moisture buildup
Pruning
  • Remove dead, damaged, or overcrowded radial stems to improve air circulation and maintain plant shape
  • Trim back leggy stems to encourage compact, uniform growth in spring
  • Avoid cutting the central caudex unless absolutely necessary, as it is the plant's primary water storage organ
