Water thoroughly when the top few centimeters of soil feel dry. Ozothamnus antennaria prefers well-drained conditions and is relatively drought-tolerant once established. Avoid waterlogging, which can lead to root rot.

Reduce watering frequency during winter months when the plant is dormant.

Prune after flowering to maintain shape and encourage bushier growth. Remove dead, damaged, or crossing branches at any time. Light shaping can be done in early spring before new growth begins.

Heavy pruning is best avoided to prevent stressing the plant.

Propagate from semi-hardwood cuttings taken in summer. Insert cuttings into a well-draining propagation mix and keep them in a humid environment with bottom heat.

Alternatively, sow seeds in spring, though this may result in less predictable results compared to cuttings.

Repot young plants annually or as needed, usually in spring. Established plants prefer to be slightly pot-bound and do not require frequent repotting.

Use a well-draining potting mix, such as one containing grit or perlite. Ensure the new pot has adequate drainage holes.
