How to trim hedges

Overview

Hedges need regular trimming to keep in good shape and promote healthy, dense growth. You should trim 3-4 times per year at the turn of the season for the best results. We'll show you how to trim non-established hedge along the top, leaving the sides to promote growth.

Steps

1Trimming a hedge with manual shears

Start at the end of your hedge and work your way along for a consistent cut. Keep your shears level and you will get a crisp top. If you can, assess your cuts at eye-level to make sure you have done an even job.

2Trimming with battery hedge shears

When trimming hedges with electric or battery-operated shears, it's important to maintain an even flow when you cut. This is the easiest way to get a crisp line on your hedge. Make sure that you keep the trimmer at a horizontal position so you avoid an uneven line.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
