Allow the soil to dry out completely between waterings. In summer, water thoroughly when the soil is dry. Reduce watering significantly in winter, providing only enough to prevent the stems from shriveling.

Overwatering is the most common cause of rot in Tephrocactus species.

Pruning is generally not required for Tephrocactus verschaffeltii unless removing damaged or diseased segments. If you need to propagate or shape, use a clean, sharp knife to detach segments.

Allow the cut surface to callus over for a few days before replanting.

Propagation is typically done by stem cuttings. Carefully remove a segment and allow it to dry and callus over for several days to a week. Then, plant the callused segment into a well-draining cactus mix.

Rooting usually occurs within a few weeks.

Repot Tephrocactus verschaffeltii every 2-3 years, or when the plant outgrows its container. Use a gritty, well-draining cactus mix. Repot in the spring before the active growing season begins.

Ensure the pot has drainage holes to prevent waterlogging.
