Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot.

Allow the top few centimeters of soil to dry out slightly between waterings for established plants.

Deadheading spent flowers regularly will encourage more blooms and prevent self-seeding if unwanted. Trim back any leggy or overgrown stems in late summer to maintain a tidier appearance and potentially promote a bushier habit.

Crepis tectorum is easily propagated by seeds sown directly into the garden in early spring or autumn. Seeds germinate readily. Division of established clumps in spring or autumn is also a viable method.

As Crepis tectorum is typically grown as an annual or short-lived perennial and often self-seeds, repotting is usually not necessary. If grown in containers, repot young plants in fresh potting mix annually in spring.
