Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry spells, keeping the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings. Reduce watering in winter when growth slows.
Ensure good drainage to prevent root rot.
Deadhead spent flower stalks to encourage further blooming and prevent seed formation. In late autumn or early spring, remove any dead or damaged foliage to maintain plant health and appearance.
This also helps in tidying up the plant.
Propagate by division of clumps in early spring or autumn. Carefully separate the root ball into sections, each with a few healthy shoots and roots. Replant immediately into prepared soil, watering well.
Repot container-grown plants every 2-3 years in spring. Choose a pot only slightly larger than the current one with fresh, well-draining potting mix. Ensure the new pot has adequate drainage holes.
