Sustainable landscaping starts with tree choice. The right species store carbon, filter air, support wildlife and need little input. Pick well and the garden does the work for you.
What sustainable trees deliver
-
Carbon storage. Trees pull CO2 from the air and lock it into wood and soil.
-
Air quality. Leaves filter dust and produce oxygen.
-
Water management. Roots reduce runoff and improve soil structure.
-
Biodiversity. Native species feed birds, insects and small mammals.
-
Energy savings. Shade trees reduce summer cooling costs.
Four sustainable choices
Corymbia maculata (Spotted Gum)
Iconic Australian native. 15-25m tall. Carbon storage, wildlife habitat and shade in one tree.
Waterhousea floribunda (Weeping Lilly Pilly)
Native screening tree that filters air and supports birds. 6-10m tall. Dense hedge with low input.
Olea europaea (Olive)
Edible fruit, evergreen foliage, no irrigation needed. 4-8m tall. Sustainable food garden anchor.
Brachychiton populneus (Kurrajong)
Native shade tree that handles drought without irrigation. 10-15m tall.
Tips for sustainable tree selection
- Choose natives or proven adaptable species.
- Position trees to shade summer-facing walls.
- Mulch deeply to reduce water demand.
- Allow proper mature size to avoid early replacement.
FAQs
How often should I water new trees?
Deep weekly watering through the first year. Native and Mediterranean species are drought tolerant after that.
What's the best season to plant?
Autumn or early spring. Cool soil, steady moisture, low stress.
How do trees reduce energy use?
Deciduous shade trees on the north and west sides reduce summer cooling load while letting in winter sun.
