Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, as feathertop prefers drier soil.

Prune feathertop in late winter or early spring before new growth begins. Remove dead, damaged, or overcrowded stems to improve air circulation and shape.

Cut back to the ground or to a desired height to encourage a tidier appearance. Deadheading spent flower spikes can prevent unwanted reseeding.

Feathertop is easily propagated from seed sown in spring. Surface sow seeds in well-draining compost and keep moist. Alternatively, division of established clumps in spring is also effective.

Young plants establish relatively quickly.

Repot feathertop only when necessary, typically every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix. Repotting is best done in spring.

Ensure the new pot has adequate drainage holes to prevent water retention.
