Water Acanthocereus chiapensis thoroughly when the soil is completely dry, typically every 2-4 weeks in the growing season.

Reduce watering significantly in winter, allowing the soil to dry out between waterings to prevent root rot. Ensure good drainage to avoid waterlogged conditions.

Prune Acanthocereus chiapensis primarily to manage its size, shape, or to remove dead or damaged stems. Use clean, sharp tools to make cuts at joints or where new growth is desired.

Pruning is best done in spring before the active growing season begins.

Propagate Acanthocereus chiapensis from stem cuttings. Allow cuttings to callus for several days to a week before planting in a well-draining cactus mix.

Roots will typically form within a few weeks to months, after which you can treat it as a mature plant.

Repot Acanthocereus chiapensis every 2-3 years or when it outgrows its container. Choose a pot that is only slightly larger than the current one, with ample drainage holes.

Repot in spring using a gritty, fast-draining cactus soil mix.
