Watering, pruning, propagation, and repotting details from plant data
Water regularly during dry periods, especially when young. Aim to keep the soil consistently moist but not waterlogged.
Once established, this plant is fairly drought-tolerant, but occasional watering will promote better flowering and overall health.
Deadhead spent flowers to encourage reblooming and prevent self-seeding. In late fall or early spring, cut back the dead stems to about 10-15 cm above the ground to tidy the plant and remove potential overwintering pests.
Easily propagated by division in early spring or fall. You can also collect seeds in fall, stratify them over winter, and sow them indoors in early spring. Stem cuttings can be taken in early summer.
Established plants rarely need repotting. If necessary, divide and repot in early spring or fall. This process rejuvenates the plant and can help control its spread. Ensure the new location has adequate space.
