Water: Spider cactus thrives in arid conditions, demonstrating high drought tolerance. Adapted to store water, it needs watering only once every three weeks. This cactus prefers well-draining soil to prevent root rot and is typically grown outdoors.

Fertilize: For spider cactus, use specialized 'Succulents and Cacti Food' during spring and summer, fertilizing every 4-6 weeks at quarter strength to prevent nutrient overload. Water spider cactus before feeding, and avoid fertilization in winter to ensure optimal growth and health.

Pruning: Spider cactus requires minimal pruning. Focus on removing withered flowers and branches to allow the plant to allocate nutrients to healthy growth.

Propagation: Propagation of spider cactus includes division and grafting. For division, cut and plant stem branches; new shoots will emerge. Grafting involves selecting a rootstock, positioning spider cactus at the center, and securing it, allowing 1-2 weeks for successful fusion before removing the rope.
