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, allowing the soil to dry out between waterings to prevent root rot. Overwatering is a common cause of demise for this cactus.

Pruning is generally not required for Echinocereus poselgeri unless removing dead or damaged stems. If propagation is desired, stems can be carefully removed with a clean knife.

Ensure any cut surfaces are allowed to callus over before replanting to prevent infection.

Propagate by stem cuttings or seed. Cuttings should be taken from healthy stems, allowed to callus for several days to a week, and then planted in a well-draining cactus mix.

Seeds can be sown in a sterile cactus mix and kept warm and lightly moist.

Repot your Dahlia Hedgehog Cactus every 2-3 years, or when it outgrows its current container. Choose a pot that is only slightly larger than the previous one. Use a fast-draining cactus and succulent potting mix.

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