Water moderately when the top 2-3 cm of soil feel dry. Acacia retinodes prefers well-drained soil and is somewhat drought-tolerant once established. Avoid waterlogging, which can lead to root rot.

Reduce watering during winter dormancy.

Prune lightly after flowering to shape the plant and remove any dead or crossing branches. This species tolerates pruning well and can be maintained as a shrub or small tree. Heavy pruning should be avoided.

Easily propagated from seeds sown in spring after a period of cold stratification, or from semi-hardwood cuttings taken in summer. Seeds may require scarification to improve germination rates.

Repot young plants annually or biennially in spring as needed, typically when root-bound. Mature plants rarely require repotting. Use a well-draining potting mix, such as a sandy loam.
