Watering, pruning, propagation, and repotting details from plant data
Water sparingly once established, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot. In containers, water thoroughly when the top few centimeters of soil feel dry.
Reduce watering significantly during winter dormancy.
Prune in late winter or early spring before new growth begins. Remove dead or damaged foliage and any spent flower stalks from the previous season. This encourages healthy new growth and maintains a tidy appearance.
Deadheading is not typically necessary for this species.
Propagate by division of established clumps in early spring. Carefully separate the root ball into smaller sections, ensuring each section has roots and shoots. Replant immediately into well-draining soil.
Seed propagation is also possible, sowing seeds in autumn or early spring.
Repot container-grown plants only when necessary, typically every 2-3 years, or when the plant becomes root-bound. Choose a pot with excellent drainage. Use a gritty, well-draining potting mix.
Repotting is best done in early spring before active growth commences.
