Ensure Your Trees Survive and Thrive Through Drought

Five drought-hardy trees plus deep watering, mulching and drip irrigation strategies that keep Australian gardens alive through 30C and above.

Dry spells are part of the rhythm of Australian gardens. Choose trees built for it and water smart, and your garden stays green through 30C and above.

Here are five drought-hardy trees we recommend at Evergreen Trees Direct, plus the watering and planting strategy to back them up.

Pick the right trees

Mediterranean and Australian natives lead the field. Deep taproots, waxy or silvery foliage and slow steady growth all add up to drought resilience. Choose species adapted to dry conditions and they coast through summer with ease.

Watering strategies through dry spells

Deep watering

Water slowly so it penetrates 30cm down. Deep watering grows deep roots that handle warm weather with ease. Once a fortnight in summer is plenty for established trees.

Mulch heavily

10cm of organic mulch retains moisture, regulates soil temperature and feeds soil microbes. Keep mulch a hand's width clear of the trunk for a healthy collar.

Drip irrigation

Delivers water to the root zone with zero evaporation loss. Worth the install for any garden over 100sqm.

Timing

Early morning or late evening only for the most efficient watering, and summer planting works beautifully with morning and evening watering for the first two weeks.

Planting tips for drought success

Dig a hole twice the width of the rootball but only as deep. Mix compost into the backfill. Water immediately after planting to settle soil. Stake young trees against summer wind. The first 18 months matter most: deep roots formed early carry the tree through every dry spell afterwards.

FAQs

How often should I water drought-tolerant trees? Once established, deep water once every 2-3 weeks through prolonged dry spells.

Is mulch essential? Yes. It's the single highest-return move you can make in a dry garden.

Can I prune during a dry spell? Light prune for deadwood is fine. Save heavier pruning for cooler seasons.

Choose the right trees, water deep and slow, mulch heavily, and your garden stays green through anything.
