Water thoroughly when the soil is completely dry, typically in spring and summer. Reduce watering significantly during the dormant period in fall and winter to prevent root rot.

Ensure excellent drainage to avoid waterlogged conditions, as this cactus is highly susceptible to overwatering.

Pruning is rarely necessary for Espostoa frutescens, as it maintains a natural columnar growth habit. If removing damaged or diseased stems is required, use a clean, sharp knife or saw.

Sterilize tools between cuts to prevent the spread of pathogens. Pruning is best done in spring before active growth begins.

Propagation is primarily done through stem cuttings. Allow cuttings to callus over for several days to weeks in a dry, shaded area before planting in a well-draining cactus mix.

Rooting typically occurs within a few weeks, after which standard cactus care can be applied. Seeds can also be used but are slower.

Repot only when the plant becomes root-bound or outgrows its container, typically every 2-3 years. Use a well-draining cactus or succulent potting mix. Choose a pot that is only slightly larger than the current one.

Repotting is best performed in spring before the active growing season begins.
