When should I trim trees?

Trees must be trimmed if they are too close to powerlines. In the north of Western Australia, trees should also be trimmed before the summer cyclone season (November- April). Trees in the Mid West and southern parts of the State should be trimmed before winter.

Horizon Power regularly conducts inspections of powerlines to identify where vegetation is growing too close.

As a general rule, trees should be no closer than three metres to powerlines.
