Water regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Reduce watering slightly in cooler months.

Check soil moisture with your finger before watering; allow the top few centimeters to dry out between waterings to prevent root rot.

Prune to shape the tree, remove dead or diseased branches, and improve air circulation. Focus on removing crossing branches and suckers.

Light pruning can be done after harvesting, with heavier structural pruning best performed when the tree is young to establish a strong framework.

Macadamia tetraphylla is primarily propagated by grafting or budding onto rootstock, as seedlings can be variable and take many years to fruit. Cuttings can be successful but are more challenging.

Use fresh seeds from ripe nuts if starting from seed, sowing them in well-draining potting mix.

Young trees benefit from repotting every 1-2 years into a slightly larger container as they outgrow their current one. Mature trees in the ground do not require repotting.

Use a well-draining potting mix, ideally with added organic matter, to ensure good aeration for the roots.
