Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in late summer and fall as the plant enters dormancy.

Ensure good drainage to prevent root rot.

Deadhead spent flowers to encourage a second bloom and prevent self-seeding if unwanted. Cut back the foliage to the ground in late fall or early spring before new growth emerges.

Remove any dead or damaged stems promptly.

Sow seeds in fall or early spring. Division of established clumps is best done in early spring or fall. Take basal cuttings in late spring or early summer and root them in moist potting mix.

Container-grown plants benefit from repotting every 2-3 years, typically in early spring before active growth begins. Use a well-draining potting mix. Ensure the new pot is only slightly larger than the current one.
