Canberra summers are hot, dry, and often unforgiving. Shade makes a huge difference — not only for comfort outdoors but also for reducing the heat load on homes. Planting the right trees can lower cooling costs in summer while still allowing precious sunshine through in winter.
Unlike evergreens, deciduous trees are the ideal solution for passive energy management. They provide leafy cover in summer, then drop their leaves in winter to let the sun warm your house and garden.
Here are some excellent small to medium trees that establish quickly, stay manageable, and thrive in Canberra’s frosty, low-rainfall climate.
