Ligurian YarrowAchillea ligustica

Water Southern Yarrow regularly during its establishment phase, especially in hot, dry conditions. Once established, it is quite drought-tolerant and prefers well-draining soil.

Overwatering can lead to root rot, so allow the soil to dry out slightly between waterings.

Prune Southern Yarrow after the main flush of flowering to encourage a tidier appearance and potentially a second bloom. Cut back spent flower stalks and any leggy stems.

In late autumn or early spring, remove dead foliage to promote new growth.

Propagate Achillea ligustica by division in early spring or autumn. Carefully separate clumps, ensuring each section has roots and shoots. You can also propagate from basal cuttings taken in late spring.

Sow seeds in spring, either indoors or directly outdoors.

Repotting is generally not necessary for Achillea ligustica as it prefers to be slightly root-bound and thrives in well-drained, often lean soil. If container-grown plants become excessively root-bound, repot in spring into a slightly larger pot with fresh, gritty potting mix.
