Water thoroughly when the soil is completely dry, typically every 2-4 weeks during the growing season (spring to early autumn). Reduce watering significantly in winter, allowing the soil to dry out between waterings.

Overwatering can lead to root rot.

Pruning is generally not required for Espostoa mirabilis, as it grows slowly and maintains a columnar shape. If a stem becomes damaged or diseased, or if you wish to control its size, use a clean, sharp knife or saw.

Sterilize tools between cuts.

Propagation is best done by stem cuttings. Allow cuttings to callus over for several days to a week before planting in well-draining cactus mix. Roots typically form within a few weeks to months.

Propagate in spring or early summer.

Repot Espostoa mirabilis every 2-3 years or when it outgrows its container. Use a well-draining cactus or succulent potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering.

Repot in spring.
