Water regularly, especially during dry periods, ensuring the soil is kept consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings once established.

Reduce watering in winter to prevent root rot, as the plant enters dormancy.

Pruning is typically not essential for Anchusa arvensis. Deadheading spent flowers can encourage a longer blooming period and prevent self-seeding if unwanted.

Remove any yellowing or damaged foliage as needed to maintain a tidy appearance. Light trimming can shape the plant.

Anchusa arvensis is easily propagated by seeds sown directly into the garden in autumn or early spring. Alternatively, sow seeds indoors a few weeks before the last frost.

It can also be propagated from cuttings taken in late spring or early summer, though this is less common.

Repotting is generally not necessary for this annual or short-lived perennial. If grown in a container and it becomes root-bound, repot in spring into a slightly larger pot using well-draining potting mix.

However, it is often treated as an annual and allowed to reseed.
