How to Choose a Hedge Trimmer
Choosing the right hedge trimmer depends on your garden size, hedge type, and whether you prefer cordless freedom, corded power, or petrol muscle. This guide breaks down the key specs and features to help you find the best tool for your hedges.

Stihl HSA 56
Best all-round cordless hedge trimmer for medium gardens.
What type of hedge trimmer do you need?
Hedge trimmers come in three main power types: cordless (battery), corded (electric), and petrol. Cordless models are the most popular for their portability and ease of use, though they require battery investment. Corded trimmers offer unlimited run time but are limited by the power cord. Petrol trimmers are the most powerful but are heavier and require more maintenance.
Your choice should be guided by the size of your garden and the thickness of the hedges you need to cut. For small gardens with light trimming, a cordless or corded trimmer is ideal. For large, thick hedges, a petrol model might be necessary.
Key specifications to consider
When choosing a hedge trimmer, focus on blade length, cutting capacity, and weight. Blade length determines how much you can cut in one sweep. A 20-inch blade is a good all-rounder. Cutting capacity refers to the thickness of branches the trimmer can handle. Most models can cut branches up to 1 inch thick. Weight is crucial for comfort during extended use.
Battery voltage and amp-hour (Ah) ratings are important for cordless models. Higher voltage (36V or 40V) provides more power, while higher Ah (4.0Ah or 5.0Ah) offers longer run time. Always consider the brand's battery ecosystem if you already own other tools from the same manufacturer.
What to check before buying
- Blade material: Look for hardened steel blades that stay sharp longer. Some models have anti-friction coatings for smoother cuts.
- Safety features: A two-hand switch or trigger guard is essential to prevent accidental starts. A hand guard protects your fingers from branches.
- Ergonomics: A rotating rear handle or adjustable front handle improves comfort for vertical and horizontal cuts. A soft-grip handle reduces vibration.
- Noise level: Cordless and corded models are quieter than petrol. Check the decibel rating if noise is a concern.
- Warranty: A 2-year warranty is standard. Some brands offer up to 5 years for the tool and 3 years for the battery.
Mistakes to avoid
- Buying too much power: A heavy petrol trimmer is overkill for small hedges and will tire you out quickly.
- Ignoring battery compatibility: If you already own a brand's tools, stick with the same battery system to save money on extra batteries and chargers.
- Choosing a short blade for large hedges: A 16-inch blade will take much longer to trim a long hedge than a 24-inch blade.
- Forgetting about maintenance: Petrol trimmers need fuel mixing and regular servicing. Cordless models just need battery charging.

Stihl HSA 56
Best OverallPros
- Excellent build quality from Stihl
- Good balance and ergonomics
- Quiet operation
Cons
- Battery and charger sold separately
- Not the cheapest option
The Stihl HSA 56 is a well-built cordless hedge trimmer that delivers consistent performance for medium-sized gardens. Its 20-inch blade is a versatile length for most hedges, and the 36V system provides enough power for branches up to 1 inch thick. Owner reviews frequently praise its smooth cutting action and low vibration levels, making it comfortable for extended use.
The main drawback is that the battery and charger are not included in the base price, which adds to the upfront cost. However, if you already own Stihl's AK battery system, this trimmer is a no-brainer. It is lighter than many petrol alternatives and much quieter, making it a considerate choice for suburban gardens.
Ryobi RHT18X
Best BudgetPros
- Very affordable
- Part of Ryobi ONE+ system
- Lightweight and easy to handle
Cons
- Limited cutting capacity
- Not ideal for thick branches
The Ryobi RHT18X is an excellent entry-level hedge trimmer for small gardens and light trimming tasks. It uses the popular Ryobi ONE+ 18V battery system, so if you already own Ryobi tools, this is a cost-effective addition. At just 4.8 lbs, it is one of the lightest trimmers available, reducing fatigue during use.
However, its cutting capacity is limited to 0.75 inches, meaning it struggles with thicker branches. Owners report that it is best suited for regular maintenance trimming rather than heavy-duty cutting. For the price, it offers good value, but it is not a tool for tackling overgrown hedges.
Bosch EasyHedgeCut 60
Best CordedPros
- Unlimited run time
- Long 24-inch blade
- Powerful cutting capacity
Cons
- Limited by power cord
- Heavier than cordless models
The Bosch EasyHedgeCut 60 is a powerful corded hedge trimmer that offers unlimited run time, making it ideal for large gardens with long hedges. Its 24-inch blade is one of the longest available, allowing you to cover more area with each pass. The 500W motor provides ample power for branches up to 1.2 inches thick.
The main limitation is the power cord, which can be inconvenient if your garden is far from an outlet. It is also heavier than cordless alternatives at 6.2 lbs, which can be tiring for overhead trimming. However, for consistent, heavy-duty use without worrying about battery life, this is a top choice.
DeWalt DCHT820P1
Best for Heavy DutyPros
- Powerful motor for thick branches
- Durable build quality
- Good battery life with 5.0Ah pack
Cons
- Heavier than most cordless models
- Higher price point
The DeWalt DCHT820P1 is a heavy-duty cordless hedge trimmer designed for tough jobs. Its 20V MAX system with a 5.0Ah battery provides plenty of power for thick branches up to 1.25 inches. The 22-inch blade is a good length for large hedges, and the anti-lock system prevents the blade from jamming.
At 6.5 lbs, it is heavier than many competitors, which can be a downside for extended use. However, owners report that the power and build quality justify the weight. It is an excellent choice for users who already own DeWalt 20V tools and need a trimmer that can handle overgrown hedges.
Makita DUH601Z
Best Long ReachPros
- Longest blade in its class
- Excellent reach for tall hedges
- Part of Makita LXT system
Cons
- Heavy at 7.1 lbs
- Battery not included
The Makita DUH601Z is a long-reach hedge trimmer with a 24-inch blade, making it ideal for tall hedges and large shrubs. It uses Makita's 18V LXT battery system, which is one of the most extensive in the industry. The blade is designed for clean, precise cuts, and the tool is well-balanced despite its length.
Its main drawback is the weight. At 7.1 lbs, it is one of the heaviest cordless trimmers, which can be tiring for overhead work. It is also a bare tool, meaning you need to buy a battery and charger separately. However, for users with tall hedges who need extra reach, it is a top performer.
FAQs
What is the best blade length for a hedge trimmer?
A 20-inch blade is the best all-round length for most gardens. Longer blades (24 inches) are better for large hedges, while shorter blades (16-18 inches) suit small gardens.
Are cordless hedge trimmers as powerful as corded ones?
Modern cordless models with 36V or 40V systems are nearly as powerful as corded trimmers for most tasks. Corded trimmers still offer unlimited run time but are limited by the power cord.
How long does a cordless hedge trimmer battery last?
Battery life varies by model and usage, but most 4.0Ah batteries provide 30-60 minutes of continuous trimming. Higher Ah batteries last longer.
Can I use a hedge trimmer on wet hedges?
It is not recommended to use any hedge trimmer on wet hedges. Wet branches can cause the blades to slip and increase the risk of accidents.
What is the difference between single-sided and double-sided blades?
Double-sided blades cut in both directions, making them more efficient for general trimming. Single-sided blades are better for precision work and shaping.
Do I need a petrol hedge trimmer for thick branches?
Petrol trimmers offer the most power for very thick branches, but high-voltage cordless models (36V+) can handle branches up to 1.25 inches thick.
How do I maintain my hedge trimmer blades?
Clean the blades after each use and apply a light lubricant. Sharpen the blades annually or when they start to tear rather than cut cleanly.
Is a heavier hedge trimmer better?
Not necessarily. Heavier trimmers can be more powerful but cause fatigue. Choose a weight you can comfortably handle for the duration of your trimming tasks.
Can I use a hedge trimmer to cut grass?
No, hedge trimmers are designed for woody stems and branches. Using them on grass can damage the blades and the motor.
What safety gear do I need when using a hedge trimmer?
Always wear safety glasses, gloves, and sturdy footwear. Ear protection is recommended for petrol models. Avoid loose clothing that could get caught in the blades.
