Water regularly to keep the soil consistently moist, especially during dry periods. While it tolerates some dryness once established, it thrives with regular watering.

Avoid waterlogged conditions, which can lead to root rot. Reduce watering slightly in winter when growth slows.

Pruning is mainly done to control its spread and remove dead or damaged foliage. Cut back flowering stems after they have finished blooming in late winter or early spring to prevent excessive seeding.

Remove any yellowing or decaying leaves throughout the growing season to maintain tidiness.

Propagation is most effectively done by division of its rhizomatous root system in early spring or autumn. Simply dig up the plant and divide the fleshy roots, replanting sections with healthy growth points.

It can also spread vigorously by seed, though this is less common for home propagation.

Repotting is rarely necessary as Petasites fragrans is a vigorous spreader.

If grown in a container and it becomes root-bound, repot in early spring or autumn into a larger container with fresh, well-draining potting mix.

Due to its invasive potential, container growing is often recommended to contain its spread.
