Water deeply but infrequently, allowing the soil to dry out completely between waterings. Reduce watering significantly during the dormant winter months.

Overwatering is a common cause of root rot in senita cacti, so err on the side of caution. Ensure excellent drainage.

Pruning is generally not necessary for senita cacti unless removing dead or damaged stems. If specific shaping is desired, use a clean, sharp knife or saw. Make cuts just above a tubercle.

The plant's natural form is typically columnar and attractive.

Propagation is primarily done through stem cuttings. Allow cuttings to callus over for several days to weeks before planting in well-draining cactus mix. Rooting can be slow and requires patience.

Avoid disturbing the cutting once planted.

Repot only when the cactus becomes root-bound, typically every 2-3 years. Use a well-draining cactus or succulent potting mix. Choose a pot only slightly larger than the current one, with drainage holes.

Handle with care due to spines.
