Water thoroughly when the soil is completely dry, typically once every 2-4 weeks during the growing season (spring/summer). Reduce watering significantly in fall and winter to near dormancy, allowing the soil to dry out completely between waterings to prevent root rot.

Pruning is generally not necessary for Stenocereus pruinosus unless removing damaged or diseased sections, or to control size. If pruning, use a sharp, sterilized knife or saw.

Allow cuts to callus over before resuming regular watering to prevent infection.

Propagated primarily through stem cuttings. Allow cuttings to callus for several days to weeks before planting in a well-draining cactus mix.

Rooting typically occurs within a few weeks to months in warm conditions with bright, indirect light.

Repot young plants every 1-2 years, and mature plants every 3-5 years, or when root-bound. Use a well-draining cactus or succulent potting mix. Choose a pot only slightly larger than the current root ball.

Repot in spring or early summer.
