Have you ever caught yourself eyeing your neighbour’s hedge in envy? How did they get their hedge looking so much thicker and more lush than yours? Hedge envy is real, and the good news is that we’re here to help you get over it. Trimming is about more than just making your hedge look neat and tidy. When done to professional standards, a trimmed hedge can make perfect strangers stop in the street and admire your garden. Why be envious of your neighbour’s hedge when you could make them envious of yours?!
We know that managing hedges in Tassie gardens is a different ball game. We’ve worked with it all, from handling rapid spring growth to managing hedges that have run completely wild. The best part? Trimming a hedge doesn’t have to be a pain.
So, does trimming a hedge make it grow thicker and faster? Yes! Let us explain why, with our expert tips and tricks for the perfect trim. By the end of this guide, you will have everything you need to keep your hedges looking their absolute best.
The Benefits of Trimming Your Hedges
Hedge trimming isn’t just another gardening job—it’s a simple but powerful way to keep your hedges healthy and looking fantastic. Here are the top three benefits of regularly trimming your hedges:
Healthier & Denser Foliage
A well-timed trim redirects the plant’s energy into new shoots, making your hedge thicker and healthier. In Tassie’s ideal growing seasons—spring and summer—this can completely transform the look of your hedge, making it appear more lush.
Protection from Diseases & Pests
An overgrown hedge will keep moisture in, which can become a breeding ground for pests and fungal infections. Trimming your hedge will improve airflow and allow more sunlight in, keeping it strong and disease-free.
Enhanced Garden Aesthetics
A fuller, neatly shaped hedge is more than a border—it provides a natural, green backdrop that adds structure and definition to your garden. A denser hedge will also increase your level of privacy, making your backyard retreat more peaceful if your property faces a busy street.
Step-by-Step Guide to Trimming Hedges Like a Pro
Ready Your Tools
Ensure your tools are in good condition before you begin trimming, as blunt tools can damage and break branches you would otherwise cut easily and cleanly. You’ll need sharp pruning shears, a sturdy hedge trimmer, and a good pair of gloves.
Bonus Tip: Make a few test cuts on a less visible section of the hedge before tackling the entire job.
Time Your Hedge Trimming
Early spring, when your hedge is actively growing, is the ideal time for a major prune, as it encourages denser, healthier growth. Summer is the perfect time to reshape your hedges and maintain their size, but avoid heavy pruning during the hottest months, as this could stress the plant. We recommend only light trimming in autumn if needed, with no pruning in winter. Particularly in Tasmania, trimming your hedge in winter can expose it to frost damage.
Bonus Tip: Deep water your hedge after a spring/summer trim to reduce stress and promote strong and healthy new growth.


Shape Hedges with a Wedge for Thicker Growth
For a strong, even hedge, shape it so the base is slightly wider than the top. This allows all parts of the hedge to get enough sunlight and promotes even, healthy growth. Start trimming from the bottom and move upwards with smooth, steady strokes.
Bonus Tip: Remember to take a step back every few minutes to review your progress. It’s easy to get caught up in the details and lose sight of how your hedge looks from a distance, so regular checks will help ensure a balanced, even shape.
Common Mistakes to Avoid When Trimming Hedges
Trimming a hedge is a scary business—there is no magic eraser for your mistakes, which will be on display for all to see! Here are a few common pitfalls to steer clear of:
Trimming Too Much in One Go
Don’t take off too much at once, as this will stress your hedge and slow growth. Your hedge needs time to bounce back from a trim, so don’t remove more than a third of the growth at a time.
Ignoring Plant-Specific Trimming Needs
Some hedges can be safely trimmed often, while others prefer less trimming. It’s important to know which variety of hedge you have before you start pruning so you can tailor your approach to its specific needs.
Skipping Routine Trims
If you leave your hedge for too long, it can become a gnarly mess. Regular trims will ensure thicker, healthier growth, preventing it from becoming woody or uneven.
