Water consistently to keep the soil evenly moist, but avoid waterlogging, which can lead to root rot. Allow the top inch of soil to dry out slightly between waterings during the growing season.

Reduce watering in cooler months, especially if grown indoors.

Prune sparingly to maintain shape or remove dead or damaged foliage. If the plant becomes leggy, a light trim can encourage bushier growth. Remove spent flower stalks to prevent self-seeding if undesirable.

Best done in late spring or early summer.

Propagate by division of clumps in spring or early autumn. Carefully separate the root ball into smaller sections, ensuring each section has roots and shoots. Replant immediately into well-draining soil and water gently.

Can also be propagated from seed sown in spring.

Repot every 2-3 years in spring or early autumn, or when the plant becomes root-bound. Use a good quality, well-draining potting mix.

Choose a pot only slightly larger than the current one to avoid excessive moisture retention. Water thoroughly after repotting.
