Safe Tree Planting, Powerlines and You

Planting Guidelines
We've put together a list of helpful points on the best way to develop your garden without interfering with dangerous overhead powerlines.

• When mature, trees should not grow to within 2 metres of powerlines, that is, the powerline from the street to your home and the powerlines that run along your street or in easements (diagram 1).
• Before planting on easements always contact your local electrical supplier to check if there are any special planting requirements.
• If you want to plant taller plants, apply the 45-degree rule: Plant at a distance from the powerline at least equal to the expected mature height of the plant (diagram 2).
• Generally, palms shouldn't be planted within 5 metres of powerlines. However, several palms are suitable to plant near powerlines.
• Do not plant climbing trees or plants near the base of power poles. They can grow up into the lines and pose a safety risk or interrupt electricity supply.

Important note: High voltage powerlines have different planting guidelines. Please contact your local electrical supplier for more information.

Naturally Occurring Species
When planting, ENERGEX recommends you consider species which naturally occur in a particular area. By selecting naturally occurring species whenever possible, you will be helping the environment in many ways. The Department of Natural Resources, your local Council or local environmental groups, will be able to assist you with more information.

Planting Tips
To help provide your new 'powerline friendly plants' or seedlings with a good start, consider the following planting tips:
1. Check the quality of the soil the plant is to be placed in. Does the soil appear too sandy, heavy, clay or wet? If so, your local nursery can advise you how best to rectify the situation.
2. Always keep your new tree moist while it is in its nursery pot. Generally, water daily.
3. When planting, dig a hole for the plant that is twice the width and once the depth of the container the plant is currently housed in.
4. Water the hole you have dug for the plant, then let it drain slightly.
5. To remove your tree from its pot: Place your hand on top of the pot letting the stem of the plant sit between two of your fingers. Place your other hand under the pot. Turn the pot upside down, being careful not to damage or break the stem of the plant. Rotate the pot gently and lift it off. Using both hands, turn the plant upright again.
6. Back-fill the hole to the required depth. (When the plant is placed in the hole and covered with soil, the stem should enter the soil in the same place as when it was in the pot).
7. Place the plant gently in the prepared hole.
8. Fill the hole with soil and press firmly around the roots, do not use your foot to tread the soil down near the plant. (Consider using water crystals when back-filling to assist with moisture retention in soil).
9. Create a basin around the stem of the plant to help retain water. Place mulch around the planting area (however, not up against the stem of the plant).
10. When planting is complete, always water plants thoroughly. Water your new tree every second day for one to two weeks and then water and fertilise as required.

Always read and follow any care or planting instructions that accompany your new plant. The above tips are designed as planting and care guidelines only; following these tips does not guarantee that your plant will flourish. If you are concerned with the progress or health of a plant, consult your local nursery for advice.
