Water Diplotaxis duveyrieriana moderately, allowing the soil to dry out slightly between waterings. Ensure good drainage to prevent waterlogging, which can lead to root rot.

Reduce watering in winter when the plant is dormant or growing less actively.

Prune Diplotaxis duveyrieriana lightly after flowering to encourage bushier growth and prevent it from becoming leggy. Remove spent flower stalks and any dead or damaged stems.

This can be done in late spring or early summer.

Diplotaxis duveyrieriana can be propagated by seeds sown in spring or autumn, or by taking cuttings from semi-ripe shoots in summer. Seeds germinate best with light stratification or a period of cold.

Cuttings root readily in moist, well-draining compost.

Repot Diplotaxis duveyrieriana every 2-3 years, or when it becomes root-bound. Spring is the ideal time to repot, just as new growth begins.

Use a well-draining potting mix, such as a cactus or succulent mix, to ensure good aeration.
