Water deeply once every 3–4 weeks when soil is bone dry
Fertilization
Diluted cactus fertilizer once monthly. Suspend fertilization in winter when the cactus enters dormancy
Eggshell powder top dressing：Grind clean, dried eggshells to a fine powder; sprinkle a thin layer on the soil surface to add calcium without burning rootsPruning
- Remove dead or damaged stem sections to maintain a tidy, healthy shape
- Trim overgrown offsets to propagate new plants and reduce crowding
- Avoid cutting the woolly coat, as it protects the cactus from intense sunlight and water loss
