Trees and plants play a key role in creating healthier individuals and communities. They yield a host of benefits such as:

  • improving air quality - flourishing urban forests convert carbon dioxide into life-giving oxygen and help filter daily pollution.
  • minimising the effects of soil erosion - by acting as ecological windbreaks and sieves, via their foliage and subterranean root systems. Urban forests help retain topsoil and protect waterways from silt and other contaminants well beyond their immediate reach.
  • offering sanctuary to birds, insects and wildlife, and providing them with a source of sustenance from flowers, tree bark, and edible seeds and fruits.

Trees and plants are highly valued in the Toowoomba Region as evidenced by our expansive and flourishing urban forest.

Choosing where to plant

  • Consider the location of overhead and underground services, including the service line to your home. 
  • If your tree will grow to 5m, it should be planted 5m away from the power pole. If it will grow to 10m, it should be 10m away.
  • Call 'Dial Before You Dig' on 1100, or visit Dial Before you Dig, to request information on underground cables on, or near your property. 
  • Consider carefully which type of tree you should plant. Is it evergreen or deciduous? 
  • Will its roots, branches, sap, flowers, or fruits damage buildings, fences, footpaths, roads, foundations, or vehicle paintwork? 
  • Check the visibility from your driveway, intersection sight lines and access to your property. 
  • Consider pedestrian traffic, mail service and garbage truck access.
  • Check required clearance from street lights with your service provider.

How to plant a tree so that it thrives

  • Dig a hole 300mm from the edge of the root ball on the tree.
  • Loosen up the sides of the hole to promote root penetration.
  • Water crystals can aid in water retention.
  • Create a well around your tree with soil to help retain water and reduce water run off.
  • Place mulch to a depth of 150mm around the base of your tree, but away from the trunk to prevent rot. 
  • Thoroughly water each tree immediately after planting and as required. 
  • Once planted, water the tree regularly in dry weather (check under the mulch to see if the soil is dry). Even so-called drought-tolerant plants need to be watered regularly until their roots become established.
  • Native trees can be fertilised for much better growth. Use a fertiliser that is low in phosphorus, marked as 'P' on the label of the bag. To determine if your fertiliser is suitable, check the N:P:K (nitrogen–phosphorus–potassium) composition. Use one that contains less than 3% P; those with low P but high N and K are fine, e.g. 11:2:13.

Local tree expert and author Dr John Swarbrick collaborated with us in 2014 to produce 'Toowoomba's best trees' - an engaging, full colour publication celebrating a selection of the city's iconic trees. All of the trees mentioned within its pages are registered on the National Trust of Queensland's register of significant trees.

Copies of 'Toowoomba's' best trees are available for $5 each at Toowoomba Information Centre, 86 James Street and Toowoomba Regional Library, 155 Herries Street.

Here's an excerpt from the book.
