Water
Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Allow the top inch of soil to dry out slightly between waterings.

Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Allow the top inch of soil to dry out slightly between waterings.
Minimal pruning is typically needed. Remove any dead, damaged, or crossing stems in late winter or early spring to maintain plant health and shape.
Deadheading spent flowers can encourage a tidier appearance and potentially a second flush of blooms.
Propagate primarily through division of established clumps in early spring or fall. Seeds can also be sown in autumn, requiring a period of cold stratification for germination the following spring.
Cuttings are less commonly used.
Repotting is usually only necessary for container-grown plants, typically every 2-3 years. Repot in spring before new growth begins, using a well-draining potting mix.
Choose a pot that is slightly larger than the current one.
