Urban Heat Islands are a real thing. This is where our cities and surrounding suburbs have a lack of vegetation and instead have large expanses of dark and hard surfaces that raise the heat factor.
Planting trees and plants will cool the air, and at the same time create green vistas for us to view from indoors and outdoors.


  • Trees and plants have a kind of inbuilt air-conditioning system called
  • Interrupt solar radiation.
  • Provide shading to buildings.
  • Cool the soil directly by minimising moisture loss from the surface.
  • Produce essential emissions that clean our air.

Trees also look great, and we all know that seeing green is a good thing for us psychologically.

Trees can also provide colour in the form of flowers and autumnal foliage, backdrops to gardens, habitat for birds, insects and wildlife and fruit and nut harvests.

This is an impossibly long list, and it depends on the space, location and needs you have to determine which tree/s you will want to plant.

Always consider the tree height at maturity and remember that the root systems are generally as wide spreading as the tree is tall. You also need to think about whether the tree you are considering planting is deciduous or evergreen, and what its weed potential is in your area.
Soil preparation is key for good establishment of trees. Prepare soil by digging through  ActivGrow Soil Improver, and mulch thickly after planting with your choice of mulch, Tea Tree, Cypress, Sugar Cane or Pine Bark.
