Watering, pruning, propagation, and repotting details from plant data
Water consistently to keep the soil evenly moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Reduce watering in winter when the plant is dormant.
Prune spent flower stalks to encourage reblooming and prevent self-seeding if desired. Remove any dead or damaged foliage as needed to maintain a tidy appearance and improve air circulation.
Propagate by seed, sowing in spring or autumn. Seeds can be sown directly into the garden or started indoors. Division of established clumps can also be done in spring.
Repot young plants annually or biennially in spring as needed to provide fresh soil and space for root growth. Established plants generally do not require frequent repotting.
