Water moderately when the top 2-3 cm of soil feels dry. Avoid waterlogging, as Indigofera australis prefers well-drained conditions. Reduce watering significantly during winter dormancy.

Ensure good drainage in pots to prevent root rot. Overwatering can be detrimental to this species.

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain shape and encourage bushier growth.

Light pruning can also be done after flowering to tidy the plant. Hard pruning can be undertaken if rejuvenation is needed.

Easily propagated from seeds sown in spring. Pre-soaking seeds or scarification can improve germination rates. Cuttings can also be taken from semi-hardwood in summer and rooted in well-draining media.

Seed propagation is generally the most straightforward method for home gardeners.

Repot every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of potting soil and perlite or coarse sand. Repot in spring, just before the growing season begins.

Choose a pot slightly larger than the current one to accommodate root growth.
