Water Anaphalis triplinervis regularly during its active growing season, especially in dry periods. Allow the soil to dry out slightly between waterings.

Reduce watering significantly in winter when the plant is dormant to prevent root rot. Ensure good drainage to avoid waterlogged conditions.

Prune Anaphalis triplinervis after flowering to tidy the plant and encourage a denser habit. Cut back flowered stems to the base.

In late winter or early spring, before new growth begins, remove any dead or damaged stems from the previous season.

Propagate Anaphalis triplinervis by division in spring. Carefully dig up clumps and separate them into smaller sections, ensuring each section has roots and shoots. Replant immediately into well-draining soil.

It can also be grown from seed sown in spring.

Anaphalis triplinervis generally prefers to be slightly pot-bound and does not require frequent repotting.

If necessary, repot in spring every 2-3 years into a slightly larger container with fresh, well-draining potting mix. This also provides an opportunity to divide overgrown plants.
