Hedge Trimming Tips For Beginners

Updated: 3 days ago


In Sydney's picturesque urban landscape, hedges play a crucial role in defining property boundaries, enhancing privacy, and adding aesthetic appeal to gardens. From the lush Lilly Pilly to the classic English Box, Sydney's temperate climate supports a variety of hedge species to prosper. 

However, maintaining these lovely green barriers requires regular attention, and hedge trimming is a key aspect to ensure the health and longevity of your plants.

In this blog article, we will walk you through the essential knowledge and steps to master the art of hedge trimming.


Before you start, conduct some research to:

  • Identify your hedge’s species. This can be done easily with a plant identifier app that is downloadable on mobile phones.

  • Assess your hedge's overall health and spot any diseased or damaged sections.

  • Choose the right tools, such as manual hedge shears or electric trimmers, based on your hedge size and type.

  • Ensure your tools are clean and sharp to make clean cuts and prevent disease transmission.

  • Plan the desired shape and height of your hedge, considering its natural growth pattern. 

While research can be time-consuming, for beginners, it lays crucial foundation for a successful trim by yourself. Also keep in mind that the best time to trim your hedge varies depending on each species and their growth rate, but it typically ranges from late winter to early spring for most varieties.


If you are in the season, and have all the necessary knowledge and tools to get started, let’s have a look at how we can achieve a smooth and risk-free hedge trimming. Here are some key steps to follow:


Step 1: Prepare the Area

Your safety is always the priority, so begin your trimming by clearing the area around your hedge. Remove any obstacles that might impede your movement or pose a safety risk. Remember to lay down a tarp to catch trimmings. Not only will this prevent you from slipping on fallen branches, it also makes clean-up way more easier afterwards.


Step 2: Establish Guide Lines

If you are a first-timer who wants to achieve a straight and even trim, it is important to set up guide strings along the hedge to mark your desired height and width. This will serve as a visual reference as you work through the trimming, ensuring a uniform shape at the end of your hard work.


Step 3: Start with Major Pruning

For beginners, it is easier to start with simple and large cuts. Address any overgrown areas first by removing larger branches that extend beyond your desired hedge shape. You can also make cuts at a slight angle to promote water runoff and prevent tree diseases.


Step 4: Shape the Sides

After pinning down a rough shape for your hedge, it is best to work from the bottom up to trim the sides of the hedge. Remember to maintain a slight inward slope towards the top to allow sunlight to reach the lower branches, promoting even growth throughout the plant.


Step 5: Trim the Top

Finally, it’s time to tackle the top of the hedge. For a flat top, you can use a spirit level to ensure evenness. For a rounded top, a gentle arcing motion with your trimmer is the best for creating a smooth curve.


Step 6: Clean Up

After trimming, gather the fallen leaves and branches from the tarp and dispose of them appropriately. This not only keeps your garden tidy but also reduces the risk of pests and diseases that can thrive in decaying plant material.


Step 7: Inspect and Maintain

Once the trimming is complete, take a moment to inspect your work. Look for any areas that may need further touch-ups. Additionally, consider applying a slow-release fertiliser to promote healthy regrowth and ensure your hedge remains vibrant and lush.



In summary, hedge trimming is a skill that combines horticultural knowledge with artistic vision. While it may be challenging for beginners, mastering the basics of assessing, planning, and executing a trim can lead to beautiful, healthy hedges.
