Care Guide

Watering

Withhold water almost entirely as the plant enters summer dormancy; mist lightly only if severely shriveled.

Fertilization

Do not fertilize during dormancy.. Requires very little feeding; apply a highly diluted, low-nitrogen fertilizer once at the beginning of the autumn growing season.

Eggshell Powder:Crush washed, thoroughly dried eggshells into a fine powder and sprinkle a tiny pinch onto the soil surface at the start of autumn growth. This provides slow-release calcium to support strong cell walls without risking nutrient burn or rot.
Pruning
  • Do not prune or remove the dried, papery sheaths in summer; they protect the new plant body developing inside from heat and moisture loss;
  • Allow spent flowers to dry and fall off naturally;
  • Carefully remove completely detached, dead sheaths in late autumn only if they slide off without resistance.
