Best months by climate
Highlighted months are the usual planting window. A local nursery, seed packet and current weather forecast should take priority over a broad climate calendar.

Start well
Plant macadamia with confidence
Dig no deeper than the root ball, loosen circling roots and keep the graft union clearly above finished soil level.
- Sowing or planting depth
- Plant at the existing crown or root-ball level unless the label specifies otherwise.
- Germination or establishment
- Not normally started from seed in this guide; establishment speed depends on plant size, season and root condition.
- Spacing
- 5–8 m
- Soil
- Deep, free-draining soil with room for a permanent root system; usually ph 6.0–7.0; check the species.
Feeding
Support steady growth
Feed across the root zone in the species' active season rather than piling fertiliser near the trunk.
Water
Keep moisture balanced
Deep-water the root zone while establishing and during fruit development.
Maintenance
What to do as it grows
Water the full root zone, maintain a mulch-free collar around the trunk and shape young trees before branches become heavy.
Harvest or display
Know when it is ready
Nuts in 4–6 years. Readiness varies with variety and weather; use colour, firmness, size and the supplier's maturity notes rather than the calendar alone.
Problems and companions
Keep your patch healthy
Common watch-outs
Scale, sap-sucking insects, fruit fly, birds and fungal problems vary by species. Inspect new growth and fallen fruit regularly.
Useful neighbours
Flowering herbs and groundcovers can support pollinators outside the trunk zone. Avoid deep cultivation beneath the canopy.
People and pets
Safety note
Macadamia nuts can poison dogs. Prevent access to fallen nuts and contact a vet after ingestion.
Moving plants
Biosecurity note
Fruit, plants and soil can be restricted between Australian states and pest-control zones. Check current interstate quarantine rules before moving them.
Transparent guidance
How to use this guide
Patch gives a broad Australian starting point, not a guarantee for every variety or garden. Read the Patch methodology and sources, check the latest Bureau of Meteorology climate information, and confirm interstate restrictions through Australian Interstate Quarantine.
