Best hedge trimmers for tall & thick hedges.

When is the best time to cut hedges? 

Hedges, shrubs and bushes can become unsightly if left to grow unhindered. To keep them in good shape, it's best to cut them early spring and late summer, when the bird nesting season has come to an end.

What type of hedge trimmer do you need?

If your hedges are cared for regularly and the branches are quite thin, lower powered cordless trimmers or hedge shears should be suitable for your needs. But if your hedges or bushes are dense and tough, more strength is needed, so you should go for long reach hedge trimmers and more powerful corded or telescopic hedge trimmers.

Hedge trimmer blade length

The longer the blade, the more hedge you can trim at once, helping you achieve quicker, neater results. If you’re working with small hedges, a small hedge trimmer with a blade under 50cm should be ideal. For taller or wider hedges, opting for a long reach hedge trimmer as known as a pole hedge trimmer or extendable hedge trimmer gives you the extra height and reach needed to tackle larger areas with ease.

Hedge trimmer features explained

Check out some other things you should consider before making your choice.

Carousel

  1. Power output

    Electric trimmers' power is measured in watts, ranging from 400W to 900W; cordless trimmers use volts, ranging from 18V to 36V and petrol trimmers use CCs, ranging from 20cc to 40cc.

    • Teeth spacing

      Teeth spacing relates to branch thickness - the more space between a blade's teeth, the thicker the branches it can cut. Spacing ranges from 15mm to 34mm.

      • Cable length

        If you're considering an electric trimmer, choose a model which offers enough cable to reach a household plug socket. If this isn't possible, an extension lead will come in useful.

        • Battery life

          Running time of cordless trimmers can vary between 30 to 75 minutes. When the battery does run out, many have quick charging abilities, so you can get back to work within an hour.

          • Weight

            You could be spending a lot of time carrying your trimmer, so make sure it's a weight you're comfortable with. Petrol trimmers are the heaviest, and electric trimmers the lightest.

            • 270 degree power handle

              Some types of hedge trimmer have a power handle that rotates 270 degrees. This allows you to comfortably hold down the handle no matter what position you hold the trimmer in.

              Hedge trimmer safety tips

              When you purchase a hedge trimmer, you should also select some basic safety gear, like head and eye protection, and garden gloves, to keep you safe during trimming.

              Four features for safe hedge trimming

              1. Hand guard - All blades come with a hand guard that prevents your hands from slipping onto the blade. They also protect them from being scratched by flying debris during use.
                 
              2. Dual safety switch - This is where you have to press and hold two power switches before the hedge trimmer will turn on. The blade automatically turns off if a single switch is released, keeping you safe if you slip or drop it.
                 
              3. Quick stop brake - A brake system ensures that once you stop using the trimmer, the blades will cease moving in moments, reducing the risk of accidental injury.
                 
              4. Anti-jamming system - This will either stop the blades immediately if they become jammed due to a blockage, or they will reverse the blade's direction so the blockage can be dislodged.

              Hedge trimmer maintenance tips

              • You can clean your hedge trimmer at regular intervals by using mild soap and water on the blade after use.
              • Store hedge trimmers in a clean and dry place.
              • When it's not in use, keep your trimmer in a safe place with the blade cover on, so it remains protected.
              • Take out the battery when storing, if you are not going to use your trimmer for a longer period of time - such as during the off-season in winter.

                Frequently asked questions about hedge trimmers

                What is the best hedge trimmer to buy?

                Still wondering what to consider when choosing a hedge trimmer? Here are some top tips:

                • Look for the right reach trimmers to suit your respective hedge sizes.
                • Consider teeth spacing and blade length. Wider teeth spacing and longer blades work better for thicker and taller hedges.
                • Choose a battery operated or petrol hedge trimmer that are easier for heavy use. Go for affordable corded hedge trimmers for regular use.

                What is better: cordless or corded hedge trimmer?

                Both corded and cordless trimmers have their benefits. Cordless hedge trimmers are convenient to use and offer flexible and efficient use for medium gardens. Meanwhile, corded trimmers are good for smaller gardens and are a more affordable option.

                What time of year to cut hedges UK?

                To keep your hedges well-maintained, it's best to cut them early spring and towards the end of summer, after bird nesting season has ended.

                What is the difference between a hedge trimmer and a hedge cutter?

                Hedge trimmers often refer to options for regular use and shaping or maintaining small or medium gardens. On the other hand, hedge cutters indicate heavier use and provide more power to cut thicker growth.

                How to trim a hedge properly for beginners?

                First, use the above guide to make sure you have the right hedge trimmer for your needs. Next, begin with the sides of your hedges and trim slightly while working your way to the tops, shaping them as you go. Make sure you also take necessary safety precautions while doing this. Read more about rules for hedge trimming for detailed guidance.

                Is 18V powerful enough for a hedge trimmer? 

                Yes, an 18V hedge trimmer is usually powerful enough for light to medium trimming and is ideal for routine garden maintenance. However, an 18V model may not be sufficient for more demanding tasks involving tough, woody branches or heavily overgrown hedges. In those cases, you will need a hedge trimmer with at least 24V to 40V of power.

                Are cordless hedge trimmers worth it? 

                Yes, cordless hedge trimmers, also known as battery hedge trimmers are definitely worth it for most gardeners as they are lightweight, easy to manoeuvre, low‑maintenance, and free from fuel and cord hassles. They are especially useful for lighter, routine hedge trimming, but they may struggle when dealing with thicker branches.

                Which is better 18V or 36V hedge trimmer? 

                The best choice between 18V or 36V depends on your trimming needs. A 36V hedge trimmer generally delivers more power and is therefore more suited for tackling dense or tough hedges. An 18V hedge trimmer would be more useful if you want something lighter and convenient for smaller hedges.

                Which hedge trimmer cuts the thickest branches?

                The best hedge trimmer for cutting the thickest branches is usually a high‑voltage or heavy‑duty model, such as corded or gas-powered hedge trimmers. With power rating ranging from 24V to 36V or even up to 40V in certain models, these are more effective for trimming woody, dense hedges than standard hedge trimmers.
