Water Diplotaxis acris moderately, allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot, especially in poorly draining soils.

Ensure good drainage and water more sparingly during cooler months or when the plant is dormant.

Prune Diplotaxis acris lightly after flowering to maintain a tidy shape and encourage bushier growth. Remove any dead, damaged, or crossing stems at any time.

Pinching back young plants can help promote a more compact habit and increase flower production.

Propagate Diplotaxis acris by seed sown in spring or autumn. Seeds can be sown directly into the ground or in pots. Softwood cuttings can also be taken in late spring or early summer and rooted in well-draining compost.

Division of established clumps is also possible in spring.

Repot Diplotaxis acris every 2-3 years or when it becomes root-bound. Use a well-draining potting mix, such as a mixture of loam, sand, and compost.

Repot in spring before new growth begins to minimize transplant shock and ensure good establishment.
