Water
Water regularly, especially during dry periods, but ensure well-draining soil to prevent waterlogging. Allow the soil surface to dry out slightly between waterings.
Reduce watering in cooler months when growth slows down.

Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry periods, but ensure well-draining soil to prevent waterlogging. Allow the soil surface to dry out slightly between waterings.
Reduce watering in cooler months when growth slows down.
Prune back dead or damaged foliage in late winter or early spring before new growth emerges. This helps to tidy the plant and encourage vigorous new shoots.
Remove any unsightly browned leaves throughout the growing season as needed.
Easily propagated from seed sown in spring or autumn, or by division of established clumps in spring. Ensure seeds are sown in well-draining soil and keep moist until germination.
Division should be done carefully to minimize root disturbance.
Not typically a plant that requires frequent repotting, especially when grown in the ground. If grown in containers, repot every 2-3 years in spring into a slightly larger pot with fresh, well-draining potting mix.
