The best strimmer can tackle the parts of your garden that your lawnmower just can’t reach. And while we might have perfected the velvety, bowling green-neatness of the grass by pacing up and down with the mower, there are some parts that are trickier to deal with.

A  strimmer (or trimmer as they are also called) can give you crisp edges along your borders, take down the long blades round the bases of washing lines, water features, garden furniture and trees, and even get right under bushy hedges.

How to buy the best strimmer

When it comes to powering a grass strimmer, there are three options. Choose the one that best suits your needs.

Cordless: Battery powered, these give you the freedom to roam up and down unencumbered by the length of a plug-in cord, particularly useful if your garden is long and narrow. Cutting time is limited to how long the battery charge will last, unless you invest in a spare that you can switch easily.

Cable: This plugs into the socket so your run time is limitless. The cable style strimmers also tend to be a cheaper option. However, even if the cord is long enough to stretch to the end of the garden without an extension, movement can be limited as you flip it out of the way of the cutting head.

Petrol: These offer maximum power and freedom of movement, and you can tackle heavier growth than grass, such as shrubbery. Excellent if you have a large garden to work on. But they can be heavier, noisier and smellier. You will also have to factor in fuel and maintenance costs.

What to look for in a strimmer

Lightweight: Too heavy and it can make your arms ache and make it uncomfortable to work for long periods of time.

Ergonomic: You need a comfortable grip and to prevent strain on the neck, arms and shoulders. Adjustable shafts means you can get your trimmer to suit your height perfectly.

Convenience: Cordless and petrol offer more freedom of movement but corded means no limit on the time you can spend cutting.

Power: Look at the power output on an electric trimmer, battery voltage on a cordless and engine capacity on a petrol trimmer. The bigger the number, the heavier the work you can do.

Special features: Rotating and adjustable heads widen the scope of what you can do with your trimmer, allowing you to cut vertically and horizontally.

The best strimmer cutting tools

The grass used to be ‘strimmed’ with nylon string rotated at speed so it is taut. The string gradually wears down, though this can happen quicker if you are cutting thick weeds rather than grass, or if it is impacting against hard surfaces like patio slabs, rocks or walls. They range from 1.2mm up to 3mm in diameter; the thicker they are, the better they can deal with coarse undergrowth. Heavy duty work will require the maximum thickness.

Automatic feeds on strimmers release more of the string out as needed so you don’t have to do it manually, though you will have to replace the spool when it’s empty. Bump feeds mean you tap the base on the ground to release more string, which is more controllable than an automatic feed.

Some strimmers now use plastic blades to cut. These are easily clicked on and off and tend to be more durable than the thinner nylon string, so able to tackle thicker grass and tough foliage.

The bigger the cutting width, the more grass you trim away with each sweeping move and the less time you’ll spend on the task. They usually go from 20cm up to 35cm for household models, rather than those used by professional landscapers

Top tip: To prevent string breakages when cutting thick weeds, don’t force the head into the middle of them, instead move it slowly toward the area so the weeds and stems are being cut with the tip
