Allow the soil to dry out completely between waterings. Phemeranthus brevicaulis is drought-tolerant and susceptible to root rot if overwatered. Water thoroughly when dry, ensuring good drainage to prevent waterlogging.

Reduce watering significantly during its dormant period in cooler months.

Pruning is generally minimal for Phemeranthus brevicaulis. Remove any dead or damaged foliage to maintain a tidy appearance and prevent disease. Deadheading spent flowers can encourage further blooming.

Prune lightly after flowering if shaping is desired, but avoid heavy cuts.

Phemeranthus brevicaulis can be propagated from seed or stem cuttings. Sow seeds in spring in well-draining soil.

For cuttings, take healthy stem tips in summer, allow them to callus for a day or two, and then plant in sandy, well-draining mix. Rooting typically occurs within a few weeks.

Repot Phemeranthus brevicaulis every 2-3 years, or when the plant becomes root-bound. Use a fast-draining potting mix, such as a cactus or succulent blend.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues. Repot in spring before active growth begins.
