Water regularly, especially during dry periods, but allow the soil to dry out slightly between waterings. Ensure good drainage to prevent waterlogging, which can lead to root rot.

Overwatering should be avoided as the plant prefers moderately moist soil.

Pruning can be done to maintain shape and encourage bushier growth or more blooms. Deadhead spent flowers to promote continuous flowering and prevent self-seeding if unwanted.

Light pruning in early spring can remove any winter damage and stimulate new growth.

Common Mallow is easily propagated from seeds sown directly outdoors in spring after the last frost, or indoors a few weeks prior. It can also be propagated by cuttings taken in late spring or early summer.

Division of established plants in spring is another option.

Repotting is typically necessary only for container-grown plants. This is usually done in spring before new growth begins. Choose a pot that is slightly larger than the current one, and use well-draining potting mix.

Common Mallow can tolerate being slightly root-bound.
