Fertilization
Diluted cactus fertilizer once monthly. Use low-nitrogen, high-potassium fertilizer to support healthy caudex development
Eggshell powder topdressing：Sprinkle a thin layer of crushed, baked eggshells on the soil surface; avoid mixing into the root zone to prevent unintended pH elevationPruning
