Water moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in fall and winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, which this plant dislikes.

Deadhead spent flowers regularly to encourage more blooms and maintain a tidy appearance. Cut back stems in late fall or early spring to the ground to remove dead foliage and promote new growth.

This helps prevent flopping.

Achillea × roseoalba is easily propagated by division in spring or fall. Simply dig up the clump and separate it into smaller sections, ensuring each section has roots and shoots.

It can also be propagated from basal cuttings in spring.

Repot container-grown plants every 2-3 years in spring, or when root-bound. Use a well-draining potting mix, preferably one formulated for succulents or cacti.

Ensure the new pot is only slightly larger than the previous one.
