Narrowleaf ArnicaArnica angustifolia

Arnica angustifolia prefers consistently moist but well-drained soil. Water thoroughly when the top few centimeters of soil feel dry.

Avoid overwatering, as this can lead to root rot, especially in container-grown plants. Reduce watering slightly during its dormant period in winter.

Pruning is generally minimal for Arnica angustifolia. Deadhead spent flowers to encourage further blooming and to prevent self-seeding if desired.

Remove any dead or damaged foliage in early spring before new growth emerges. Avoid heavy pruning as it can disrupt the plant's natural form.

Propagation is typically done by seed or division. Sow seeds in autumn or stratify them in a cold, moist environment for a few months before sowing in spring. Divisions can be made in early spring as new growth appears.

Ensure divisions have sufficient roots and foliage.

Repotting is usually necessary only for container-grown plants every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix, ideally with some grit.

Repot in early spring before active growth commences. Handle the roots gently to minimize disturbance.
