Keep the soil consistently moist, especially during the growing season. Avoid waterlogging, as this can lead to root rot. Reduce watering slightly in late fall and winter when the plant is dormant.

Ensure good drainage to prevent fungal diseases.

Pruning is generally not required. Remove any dead or damaged foliage in early spring before new growth emerges. This helps maintain the plant's appearance and prevents potential disease spread.

Cut back to the soil line if necessary.

Propagate by division of rhizomes in early spring as new growth begins. Carefully separate healthy sections of the rhizome, ensuring each has at least one bud. Replant immediately into well-draining soil.

Seeds can also be sown in autumn.

Repot container-grown plants every 2-3 years in early spring, or when the plant becomes pot-bound. Use a well-draining potting mix. Choose a pot that is slightly larger than the current one.

Ensure the rhizome is positioned at the correct depth.
