Allow the soil to dry out completely between waterings. Water thoroughly when the soil is dry, typically in spring and summer.

Reduce watering significantly in fall and winter, providing only enough to prevent extreme dehydration, as this cactus is susceptible to rot if overwatered.

Pruning is generally not required for Cochemiea armillata. If offsets need to be removed for propagation or to manage shape, use a clean, sharp knife or blade. Sterilize tools to prevent disease transmission.

Remove any dead or damaged parts promptly.

Propagate primarily through offsets (pups) that naturally form at the base of the parent plant.

Carefully remove offsets with a sharp, sterile knife and allow the cut surface to callus for a few days before planting in a well-draining cactus mix. "

Repot every 2-3 years or when the cactus outgrows its container, preferably in spring. Use a gritty, well-draining cactus potting mix. Choose a pot that is only slightly larger than the current one, with drainage holes.

Handle carefully to avoid spines.
