Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogged conditions, which can lead to root rot.
Allow the top inch of soil to dry out slightly between waterings for optimal growth.

Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogged conditions, which can lead to root rot.
Allow the top inch of soil to dry out slightly between waterings for optimal growth.
Prune after flowering to maintain a tidy appearance and prevent excessive self-seeding. Remove spent flower stalks to encourage repeat blooming.
Light trimming can also be done to shape the plant and remove any dead or damaged stems.
Propagate by seeds sown in early spring or fall. Division of established clumps in spring or fall is also effective. Seeds can be surface sown or lightly covered with soil. Divisions should be replanted promptly.
Repotting is generally not necessary for established perennial plants unless they become overcrowded or outgrow their container. If grown in pots, repot in spring every 2-3 years into a slightly larger container with fresh potting mix.
