Soil Type

Water: Spider-cactus thrives in arid environments and adapts to low moisture by efficiently storing water. Watering every three weeks is optimal to prevent root rot. Grown indoors, it requires well-draining soil to mimic its rocky habitat, promoting healthy root development.

Fertilize: Fertilize spider-cactus with a specific succulents and cacti formula during spring and summer, using a dilute solution monthly. Use low-nitrogen, high-potassium nutrients and avoid over-fertilization. Suspend feeding in fall and winter to match spider-cactus's dormant phase for optimal growth and vibrant blooms.

Pruning: Spider-cactus requires minimal pruning. To promote healthy growth, remove withered flowers and branches, allowing the plant to focus its nutrients on more vital parts.

Propagation: Spider-cactus is a popular cactus easily propagated by division. Offsets should be carefully separated and allowed to callous for a few days before potting in well-draining soil. Provide indirect light and minimal watering until new growth indicates successful rooting, creating clones for collections or sharing.

Repotting: Repot spider-cactus every 2-3 years in spring using a pot one size larger for its low-growing form. Ensure good drainage to avoid root rot. After repotting, provide bright indirect light and water only when the soil is dry to touch for optimal recovery.
