Water moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as Artemisia arborescens prefers well-drained conditions and can be susceptible to root rot.

Allow the soil to dry out slightly between waterings, especially during cooler months.

Prune in early spring to shape the plant, remove dead or damaged wood, and encourage bushier growth. Hard pruning can be done after flowering to maintain a compact form and prevent it from becoming too woody.

Remove spent flowers to encourage further blooming.

Propagate by semi-hardwood cuttings taken in summer or by softwood cuttings in spring. Root cuttings in a well-draining potting mix, keeping them moist and warm.

Division of established clumps in spring is also an effective propagation method.

Repot young plants annually or every two years in spring. Mature plants are often best left in place or can be rejuvenated by pruning.

Use a well-draining potting mix, such as a cactus or succulent blend, to ensure adequate drainage.
