How to Trim a Hedge: Tools & Maintenance Guide

Key takeaways: To trim a hedge, check the plant’s pruning needs, remove suitable individual branches first, then shape the new growth with a hedge trimmer. Use a compatible long-reach attachment where it lets you work safely from the ground, and collect larger cuttings before blowing loose clippings off paths. Choose each tool for the cuts you need to make, rather than expecting a hedge trimmer to handle everything.

A neat hedge takes a little planning, especially when you’ve got thick branches, an uneven top or a taller section to reach.

You don’t need every tool in the shed. To start with, we recommend a hedge trimmer, a pruning saw, a long-reach attachment and a blower. Here’s how to decide what you need and get a tidy finish.

When to cut back hedges

Check your hedge type before trimming

The right pruning time depends on the plant and whether you want flowers, a tightly clipped shape or a bigger reduction in size.

For a flowering hedge, check whether it flowers on old or new growth before cutting. Trimming at the wrong time can remove the buds you wanted to keep. A nursery can help identify the plant and its pruning needs if you’re unsure.

For regular shaping, plan light trims around the hedge’s growth rather than waiting until it needs a major cutback. Growth varies across Australia, so a fixed routine won’t suit every garden.

Choose a mild day, and postpone the work during extreme heat or when the plant is visibly struggling with dry conditions. You’ll also want dry, secure footing and weather suitable for the equipment.

Can you cut an overgrown hedge back hard?

Check the species before cutting into bare, woody growth. Many conifers won’t refill a bare patch after a deep cut.

If the hedge needs a large reduction in height or width, get plant-specific advice first. Decide how much can safely come off before choosing the cutting tool. A more powerful saw won’t solve a pruning decision that leaves the hedge unable to recover.

Which tools do you need to trim a hedge?

Hedge trimmer: for regular shaping

A hedge trimmer cuts along the outside of the hedge to control its shape and remove suitable new growth. Choose it for regular maintenance, with branches kept within the model’s stated cutting capacity.

Check cutting capacity separately from blade length. A longer blade covers more hedge in a pass, but it doesn’t tell you how thick a branch the machine can cut. If the blade catches or struggles, stop rather than forcing it through.

Our 48HD66 48V hedge trimmer has 660 mm double-sided blades and a rotating rear handle, useful when moving between the sides and top of a hedge. It weighs 3.6 kg without a battery, so try it with your chosen battery fitted to give you an idea of how heavy it’ll be to work with. 

Pruning saw: for selected woody branches

Some branches need an individual cut before you shape the surrounding growth. Use secateurs, loppers or a pruning saw suited to the branch size, access and type of cut.

A powered pruning saw is worth considering for woody branches beyond your hand tools’ capacity, provided the cuts stay within the saw’s limits. Keep the work within safe reach and away from fences, wire and other hidden objects.

Our 48MCS 48V pruning kit includes a 400 W brushless pruning chainsaw, 2Ah battery, charger and carry case. The saw weighs 1 kg without the battery and has tool-less chain tensioning, which is a great compact option for suitable individual cuts.

Hedge-trimmer attachment: for taller sections

A hedge-trimmer attachment is worth investigating when a handheld won’t comfortably reach the top. Choose one only if the complete setup lets you keep secure footing, see the cutting area and work within the manual’s approved positions.

Check the compatible powerhead, total weight and usable reach before buying. If you still need to overreach, climb or work near powerlines, bring in a professional.

Our 48T10PH hedge-trimmer attachment fits the 48TX10 multitool and has a 46 cm blade with 180-degree articulation, allowing the cutting angle to be adjusted for different faces of the hedge. The attachment weighs 2.3 kg on its own, so account for the powerhead and battery when checking the full setup.

Protective equipment and preparation

Before cutting, check the hedge for active nests, wildlife, wire and hidden supports. Clear obstacles from your feet and keep other people away from the work area.

Wear the protective equipment specified for each tool, including eye protection, gloves, sturdy footwear and hearing protection where required.

Treat the powered pruning saw as a chainsaw. Read its manual, check chain tension, lubrication and guards, and understand kickback before use. Follow chainsaw PPE requirements, including chainsaw-protective trousers or chaps, suitable boots, gloves and head, face and hearing protection. Get proper training if you’re new to chainsaws.

How to trim a hedge evenly

Set your shape before making the first cut

It’s easy to keep taking a little more off while trying to straighten a hedge. Set a guide first so you have a clear stopping point.

For a formal hedge, use stakes and a string line to mark the intended top, keeping the guide clear of the blades. Leave the base slightly wider than the top so light can reach the lower growth.

Lay a sheet or tarp beneath the hedge where it won’t create a trip hazard. It can catch much of the clipping waste and save time afterwards.

How to prune hedges before shaping

Inspect the hedge for branches that need individual attention before running the trimmer over the outside.

Remove suitable dead, damaged or unwanted branches using the correct hand tool or saw. For live branches, follow the plant’s pruning guidance and avoid leaving long stubs or cutting unnecessarily into the main stem.

Large-leaved hedges may look better when finished with secateurs because a trimmer can leave visibly sliced leaves. Choose that approach where appearance matters more than speed.

How to use a hedge trimmer

With the individual pruning finished, you can shape the softer outer growth.

1. Check the tool. Inspect the blade and guards, fit the battery correctly and follow the starting instructions.
2. Trim the sides first. Use steady, controlled passes, working upwards and keeping the blade aligned with the planned shape.
3. Take off a little at a time. Leave room to correct uneven sections rather than cutting deeply on the first pass.
4. Trim the top to your guide. Keep both hands on the handles and stay within comfortable reach.
5. Stop and check the finish. Let the blades stop before moving away to look along the hedge.

Remove the battery before clearing a blockage, adjusting the cutting equipment or handling the blade. For thick branches, change tools rather than pushing harder.

How to clear hedge clippings

Collect the larger cuttings first

Branches and heavy clippings are easier to collect by hand or with a rake than chase around with a blower.

Remove clippings left on top of the hedge, then gather the material caught on your tarp. Keep cuttings out of drains and dispose of them through suitable composting or your local green-waste service, following its rules.

Blower: for the final tidy on paths and driveways

Once the larger material is collected, a blower can gather suitable loose leaves and small clippings on hard surfaces.

Use only enough airflow to move the clippings into a collection area. Ease off around gravel and mulch, and keep dust and debris away from people, vehicles and neighbouring properties.

Our 48B800 48V blower lists 225 km/h air speed and 993 m³/h air volume, making it worth shortlisting for the final hard-surface clean-up. It has a cruise-control lever and weighs 2.5 kg without a battery.

Before putting your tools away, remove the battery and clean and maintain the cutting equipment as directed in the manual. Our guide to storing and maintaining garden tools covers more ways to look after your gear between jobs.

Take photos of your hedge and details of any batteries you already own to your local Bushranger dealer. They can help check cutting capacity, attachment compatibility and the complete tool-and-battery weight before you choose.

Frequently asked questions

When should I cut back my hedge?

Check the species and flowering cycle first. Plan light shaping around its growth, and get plant-specific advice before a heavy cutback. Avoid extreme heat and visibly drought-stressed plants.

Can I cut thick branches with a hedge trimmer?

Only within the model’s stated cutting capacity. Use suitable secateurs, loppers or a pruning saw for individual branches beyond that limit. Stop if the trimmer struggles.

How do I get a straight hedge top?

Set a string guide clear of the blades, trim lightly and stop regularly to check the line. Keep secure footing and avoid stretching to reach the far side.

Do I need all four tools?

Not necessarily. A hedge trimmer may be enough to cover regular shaping. Add a pruning saw for suitable woody branches, an attachment for safe reach and a blower if it helps with your hard-surface clean-up.
