Water regularly once the soil has dried out, especially during dry spells. Avoid overwatering, as this can lead to root rot.
Allow the soil to become moderately dry between waterings to encourage robust root development and flowering.
Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding. After flowering, you can trim back the plants to maintain a tidy appearance and promote denser growth for the following season.
Propagate from seed sown in spring or autumn. Seeds can be sown directly into the garden or started indoors. Cuttings can also be taken from semi-ripe shoots in summer for vegetative propagation.
Repot young plants in spring if they become root-bound. Mature plants generally prefer to be slightly pot-bound and may not require frequent repotting. Use a well-draining potting mix.
