Care Guide

Watering

Water once every 10–14 days when soil is fully dry

Fertilization

Diluted cactus fertilizer once every 60 days. Use low-nitrogen fertilizer to prevent soft, vulnerable stem growth

Eggshell powder top-dressing:Crush fully dried eggshells into fine powder; sprinkle lightly on soil surface, avoiding direct contact with stems to prevent moisture buildup
Pruning
  • Remove dead, shriveled stem tissue to maintain plant health and appearance
  • Trim overcrowded offshoots only if necessary, using sterile sharp tools
  • Avoid heavy pruning, as damaged stems regenerate very slowly
