Water regularly, especially during dry periods, to maintain consistently moist soil. Avoid waterlogging, as this can lead to root rot. Reduce watering in winter when the plant is dormant.

Deep watering is preferable to frequent shallow sprinkles.

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches. This encourages vigorous growth and helps maintain the plant's shape.

Harvest roots in autumn for medicinal or culinary use.

Propagate by root cuttings or division of established plants in spring. Sow seeds in early spring, either indoors or directly outdoors after the last frost.

Germination can be slow and erratic; stratification may improve success rates.

Repot mature plants every 2-3 years in spring. Use a well-draining potting mix in a larger container. This allows ample space for root development and replenishes soil nutrients.

Handle the extensive root system with care.
