Care Guide

Watering

Water thoroughly when the soil is completely dry, allowing excess water to drain.

Fertilization

Apply a diluted, balanced succulent fertilizer once.. Feed only during the active growing season; do not fertilize in winter.

Eggshell Powder:Crush washed and dried eggshells into a fine powder. Sprinkle a small amount onto the topsoil to provide slow-release calcium and improve cell wall strength. Avoid over-application to prevent soil alkalinity.
Pruning
  • Remove spent flower stalks by cutting them near the base once they have completely dried;
  • Gently pull away any dried, dead leaves at the very bottom of the rosette to maintain tidiness and prevent pest hiding spots;
  • No structural pruning is required.
