Established plants are highly drought-tolerant, requiring infrequent watering. Water deeply during prolonged dry spells, especially in extreme heat, but allow the soil to dry out completely between waterings to prevent root rot. Young plants need more regular moisture to establish a strong root system.

Prune in late winter or early spring to maintain shape, remove dead or damaged branches, and encourage bushier growth. It tolerates hard pruning well, making it suitable for hedging or shaping. Regular light trimming can help keep the plant dense and tidy throughout the growing season.

Easily propagated from semi-hardwood cuttings taken in late summer or early autumn. Cuttings should be 10-15 cm long, stripped of lower leaves, and dipped in rooting hormone before planting in a well-draining mix. Seeds can also be sown in spring, though germination can be erratic.

As a large shrub, Atriplex halimus is typically grown in the ground. If grown in a container, repotting is needed every 2-3 years into a slightly larger pot with fresh, well-draining potting mix. Ensure the container has ample drainage holes. Repotting is best done in early spring before new growth begins.
