Keep the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry slightly between waterings, especially during warmer months. Reduce watering in winter to prevent root rot.

Ensure good drainage to avoid standing water.

Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. Trim back any leggy or overgrown stems in late winter or early spring to promote bushier growth.

Remove yellowing or damaged leaves promptly.

Propagate from seed sown in spring, or by division of established clumps in early spring or autumn. Cuttings can also be taken from healthy stems in late spring.

Ensure all propagation methods use sterile media to prevent disease.

Repot young plants annually in spring. Mature plants can be repotted every 2-3 years or when they become root-bound. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid excess moisture retention.
