Care Guide

Watering

Water thoroughly when soil is fully dry; allow excess water to drain completely

Fertilization

Diluted succulent fertilizer once every 6 weeks. Use a low-nitrogen fertilizer to promote caudex growth rather than vine foliage

Eggshell powder topdress:Crush dried eggshells into fine powder and sprinkle a thin layer on soil surface to boost calcium levels and improve drainage; avoid direct contact with the caudex
Pruning
  • Trim dead, brown vines in late autumn to tidy the plant and reduce pest harborage
  • Use sterile tools to remove any soft, rotting sections of the caudex immediately
  • Avoid cutting healthy caudex tissue; only prune to remove dead or damaged growth
