Water consistently during the growing season, allowing the soil to dry slightly between waterings. In hotter climates, more frequent watering may be necessary.

Reduce watering in autumn and winter, especially if the plant is in a cooler location or dormant.

Prune lightly after flowering to encourage bushier growth and prevent excessive self-seeding. Deadheading spent blooms throughout the season will prolong flowering.

In late autumn or early spring, you can cut back established plants to maintain shape and vigor.

Anthemis cotula is easily propagated by seeds sown in spring, either directly outdoors or started indoors a few weeks prior. It also readily self-seeds in the garden.

Division of established clumps in spring is another method, though less common.

Repotting is generally not required for Anthemis cotula, as it is often grown as an annual or short-lived perennial and can become somewhat weedy. If grown in a container, repot only when root-bound, typically every 1-2 years in spring.
