Allow the soil to dry out completely between waterings. Phemeranthus calycinus is drought-tolerant and susceptible to root rot if overwatered.

Water thoroughly when the top few centimeters of soil are dry, ensuring good drainage to prevent waterlogging, especially during its dormant period.

Pruning is generally not required for Phemeranthus calycinus. Dead or spent flower stalks can be removed to maintain a tidy appearance and encourage further blooming.

Any overgrown or damaged foliage can be trimmed back in late winter or early spring before new growth begins.

Propagate by seed or division. Seeds can be sown in spring after a period of cold stratification. Division of established clumps is best done in early spring as growth commences.

Ensure divisions have adequate root systems before replanting.

Repot Phemeranthus calycinus only when necessary, typically every 2-3 years. Use a well-draining potting mix, such as a cactus or succulent blend, with added grit. Repot in spring before active growth starts.

Choose a pot only slightly larger than the current root ball.
