Water
Keep soil consistently moist, especially during the growing season. Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid waterlogging, as this can lead to root rot.
Reduce watering in the dormant period.

Watering, pruning, propagation, and repotting details from plant data
Keep soil consistently moist, especially during the growing season. Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid waterlogging, as this can lead to root rot.
Reduce watering in the dormant period.
Prune back dead or damaged stems in late winter or early spring before new growth emerges. Minimal pruning is generally required; remove any weak or crossing branches to maintain plant health and shape.
Deadheading spent flowers is not necessary.
Seeds can be sown in autumn outdoors or started indoors in early spring after a period of cold stratification. Division of established clumps in early spring or autumn is another effective method to propagate this plant.
As a perennial that prefers undisturbed roots, repotting is rarely necessary. If growth becomes stunted or the plant outgrows its container (in the case of potted specimens), repot in early spring into a slightly larger pot with fresh, well-draining soil.
