Water regularly during the establishment phase, allowing the soil to dry slightly between waterings. Once established, Kunzea ambigua is quite drought-tolerant and prefers drier conditions.

Overwatering can lead to root rot, so ensure good drainage.

Prune after flowering to maintain shape and encourage bushier growth. Remove spent flower heads and any dead or crossing branches.

Light pruning can be done to control size, but avoid heavy cuts into old wood, which may not regrow.

Propagation is best done from seed sown in spring or from semi-hardwood cuttings taken in summer. Seeds require stratification.

Cuttings should be treated with rooting hormone and placed in a well-draining medium in a warm, humid environment.

Repot young plants as needed, typically every two to three years, or when root-bound. Use a well-draining potting mix, preferably sandy or gritty. Ensure the new pot has adequate drainage holes.

Repot in spring before active growth begins.
