Water regularly to keep the soil consistently moist but not waterlogged, especially during active growth. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering in the dormant season to prevent root rot, but do not let the soil become completely dry.

Deadhead spent flowers to encourage more blooms and prevent self-seeding if unwanted. Trim back any leggy or overgrown stems in late spring or early summer to maintain a compact shape.

Remove dead or damaged foliage as needed to keep the plant tidy and healthy.

Propagate by seeds sown in fall or early spring. Seeds may require a period of cold stratification. Division of established clumps can be done in early spring or fall.

Gently separate the root ball and replant sections with healthy growth points.

Repot container-grown plants every 1-2 years in early spring before new growth begins, or when the plant becomes root-bound. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the current one to avoid over-potting.
