Creating a Low-Maintenance Garden: 6 Best Drought-Tolerant Trees

Five trees that thrive on minimal water, designed for low-maintenance gardens in dry Australian conditions.

Australian NativeDrought TolerantHardyLow MaintenanceMediterranean

The strongest low-maintenance gardens are built on drought-tolerant trees. Species that thrive on rainfall once established, ask for almost nothing through summer, and look better every year on no irrigation at all.

The six drought-tolerant picks below are the ones we recommend most often for low-water gardens.

Olea 'Manzanillo' — the Mediterranean olive. Silver foliage, sculptural trunk, decades of drought toughness.
Brachychiton rupestris — the water-storing Queensland Bottle Tree.
Banksia integrifolia — the Coast Banksia. Tough native with native habitat value.
Eucalyptus mannifera — the Red Spotted Gum. Native shade with dry-tolerant constitution.
Laurus 'Miles Choice' — the Mediterranean Bay. Aromatic foliage, low water once established.
Westringia fruticosa — the silver native low hedge. Bulletproof drought and coastal tolerance.

What makes a tree truly low-maintenance

Block size

Westringia at 1 to 1.5m. Bay and Manzanillo at 4 to 8m. Bottle Tree, Banksia, Eucalyptus at 8 to 15m.

Climate fit

All six handle hot dry conditions. Banksia and Westringia also tolerate direct coastal exposure.

Native feeding rule

Banksia, Bottle Tree and Eucalyptus prefer low-phosphorus native fertiliser.
