Water
Water regularly when the top inch of soil is dry, but allow the soil to dry out slightly between waterings. Overwatering can lead to root rot. In hotter, drier climates, more frequent watering may be necessary.
Reduce watering in winter.

Reduce watering in winter.
Deadhead spent flower clusters to encourage continuous blooming and prevent self-seeding. Cut back the foliage to the ground in late autumn or early spring to tidy the plant and promote new growth.
This also helps prevent disease.
Easily propagated from seed sown in spring or autumn. Division of established clumps in early spring or autumn is also an effective method. Cuttings can be taken in late spring or early summer.
Achillea crithmifolia is generally best grown in the ground and does not require frequent repotting. If grown in containers, repot every 2-3 years in spring when the plant becomes root-bound, using fresh, well-draining potting mix.
