Trees can be a valuable addition to any garden or streetscape but do you know which trees might be unsafe to grow in your garden? And did you know that some trees can become a maintenance nightmare if they aren't selected with the location in mind?
The usual problem is a tree that has grown too big for its position, especially under powerlines. Trees interfering with powerlines can interrupt power supply, cause damage and even threaten lives. This means the trees will need regular pruning and maintenance by qualified tree trimmers to avoid risk.
A better solution is to opt for a lower growing tree when you are planning your garden. The trick is to first find out how tall it will grow before planting and position it where it will have plenty of space to spread out. It is recommended all tree branches be kept at least two metres away from powerlines.
Safetree
ENERGEX and Greening Australia produced a list of more than 100 species of smaller growing trees that are safe to plant under and near powerlines, such as the bottle palm, dwarf banksia, and a large range of fruit trees and bottle brushes.
Trees on the Safetree list:
- grow less than four metres tall
- have a comparatively long lifespan
- are more resistant to pests and diseases
- tend not to shed bark, branches and fronds
- are best suited to the South East Queensland climate
- are not poisonous or spiky
With water-restrictions across many parts of Queensland, the Safetree list also includes water-wise trees.
A Safetree selector is available on the ENERGEX website which allows you to easily identify suitable trees and native trees for your area. Planting native trees are good for your local environment but they will also provide food and homes for native birds and animals.
More than 150 South East Queensland nurseries and garden centres have joined ENERGEX's Safetree initiative to ensure the plants are readily available. Just look for the Safetree symbol.
Another factor to consider when selecting a tree and its position is whether there are sewage pipes or underground cables nearby. ENERGEX Safetree plants are generally safe to use near underground electricity cables and gas pipes. However to be on the safe side, ENERGEX recommends planting away from all underground services on an average household block. To find out where these are, contact your local Council.
If you have an existing large tree which may need pruning, call ENERGEX on 13 12 53 or arrange a professional tree trimmer. You should never attempt to trim a tree which is near a powerline, it is extremely dangerous and life threatening.
