Water sparingly during the active growing season, allowing the soil to dry out completely between waterings.

Reduce watering significantly during the dormant period in winter, providing only enough to prevent the roots from completely desiccating. Overwatering is a common cause of rot.

Pruning is generally not required for Aylostera atrovirens unless removing dead or damaged stems. If propagation is desired, stems can be cut with a clean knife. No specific shaping is usually necessary for this cactus.

Propagation is best achieved through stem cuttings. Allow cuttings to callus over for several days to a week before planting in a well-draining cactus mix. Keep dry until roots form, then water sparingly.

Repot Aylostera atrovirens every 2-3 years or when the pot becomes overcrowded. Use a well-draining cactus or succulent potting mix.

Repot in spring just as new growth begins, handling the plant carefully to avoid damage.
