Sustainable gardens start with trees adapted to the local conditions. Native species evolved for our soils, our rainfall and our wildlife. Plant them well and the garden runs on rainfall, supports native birds and locks up carbon for decades.

Here are five natives we recommend at Evergreen Trees Direct for sustainable Australian gardens.

Planting and care tips

Choose natives suited to your region. Plant in autumn. Use low-phosphorus fertiliser only. Water through year one then leave to rainfall.

FAQs

Water needs? Minimal once established. Rainfall is usually enough.

Small garden options? Eucalyptus leucoxylon Euky Dwarf and Banksia.

Fertiliser? Native low-phosphorus blend only if soil is poor.
