Water regularly to keep the soil consistently moist, especially during dry periods. Allow the top inch of soil to dry slightly between waterings. Avoid waterlogging, as this can lead to root rot.

Ensure good drainage in pots and garden beds.

Pruning is not strictly necessary for Malva pusilla, but you can trim it back lightly in spring to encourage bushier growth. Deadheading spent flowers can promote further blooming and prevent self-seeding if unwanted.

Remove any leggy or damaged stems.

Malva pusilla is easily propagated from seed. Sow seeds directly into the garden after the last frost or start them indoors a few weeks prior. It can also be propagated by cuttings taken in late spring or early summer.

As Malva pusilla is often grown as an annual or short-lived perennial and can self-seed, frequent repotting is usually not required. If grown in a container and it becomes root-bound, repot into a slightly larger pot in spring, using well-draining potting mix.
