How to trim a hedge: step-by-step DIY guide

A neat hedge instantly gives your garden a cared-for look. With the right tools and method you can trim a hedge yourself. This blog explains what you need, how to work step by step and how to stay safe.

⚠️ Are you working high up, do you have large trees or thick branches, or are you unsure about your own safety? Leave that job to a gardener. A professional is never superfluous.

What do you need to trim a hedge?

Which tools do you need?

• hedge shears for smaller hedges and a neat finish, or telescopic hedge shears for taller hedges.
• A cordless hedge trimmer for larger hedges, if you have many metres to trim.
• A pruning saw for thicker branches that the shears can no longer handle.
• A folding ladder with handle for work on top, as long as you can stand safely.
• A hand rake or fan rake and a garden shovel to clear the clippings.

Which protective equipment do you need?

garden gloves with latex coating for grip and protection, safety goggles against flying twigs and earmuffs when using a powered trimmer. You can read more about gloves in our blog on gardening gloves and tools.

When do you trim a hedge?

Trim outside the bird breeding season. Always check that there are no nests in the hedge. Exactly how and when depends on the plant species; check the label or ask the grower. Do not trim in frost or strong sun.

Step by step: how to trim a hedge

1. Check the hedge for nests, wires and other obstacles.
2. Put on gloves, glasses and, if needed, ear defenders.
3. Stretch a string line for a straight top and side.
4. Trim from the bottom up, with the top slightly narrower than the base so light reaches all branches.
5. Use the shears for the final neat finish; saw thick branches with the pruning saw.
6. With a cordless trimmer, let the blades come to a complete stop before you remove the battery or put the tool down.
7. Rake up the clippings with the rake and cordless blower and dispose of them according to your municipality's rules.

Common mistakes

• Cutting too much at once, leaving the hedge bare.
• Working on a wobbly ladder.
• Working without gloves and glasses.
• Disturbing birds in the breeding season.

💡 It is better to trim a little more often than once drastically. That is easier on the hedge and on yourself.

Working safely

Do not work in the rain or on a slippery patio. Keep children and pets away. Always switch on the safety lock of a cordless trimmer when you pause. You can read more about safe working in our blog on safe working on the construction site.

Frequently asked questions

What is the best tool for a hedge?

For small hedges, hand shears are enough. For long hedges a cordless hedge trimmer is faster and less tiring for your arms.

How do I get a straight line?

Stretch a string at the desired height or use a batten as a guide.

When is it too late to trim?

When the hedge is in the breeding season or during frost. Wait until conditions are suitable again.

Can I trim the hedge too short?

Yes. Some species do not grow back well afterwards. Take a little each time.

When do I call in a gardener?

For large or tall hedges, for work at height or when you are unsure about your safety.
