Water regularly once the soil has dried out slightly, especially during the growing season. Avoid overwatering, as this can lead to root rot. Reduce watering in the cooler months when the plant's growth slows down.

Ensure good drainage to prevent waterlogged conditions.

Prune after flowering to maintain shape and encourage bushier growth. Remove spent flower stalks to prevent seed formation, which can drain energy from the plant. Cut back leggy stems to promote denser foliage.

Light pruning can be done anytime to remove dead or damaged parts.

Propagate from seed sown in spring, or by division of established clumps in early spring or autumn. Seeds may require stratification for better germination.

Divisions should be replanted promptly, ensuring they have adequate moisture to establish.

Repot every 2-3 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of loam, sand, and peat moss.

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