These general-purpose grass trimmers are extremely versatile. They can edge the grass, tidy areas missed by the mower and tackle small areas of long grass, too, working neatly and efficiently.

We know from years of testing that not all grass trimmers are great at all tasks, and some aren't even good at some. We've rounded up three we think are best avoided at the bottom of this page.

This basic grass trimmer is uncomfortable to use, noisy and struggles to cut through long grass. Pay a little more for a better model.

Best grass trimmers for your garden

The best grass trimmers do a wide variety of jobs quickly and efficiently. This will probably include edging the lawn, cutting the grass where it grows over your path and in areas that are hard to reach with the mower, as well as getting rid of long grass, after spring bulbs have finished flowering. For all this you need a general-purpose grass trimmer. 

  • Look for one with a rotating head that turns sideways to cut the edge of the lawn. 
  • Make sure it has an extending shaft so you can adjust it to your height.
  • On some grass trimmers the angle of the head can be adjusted so you can strim under your garden furniture, which is very useful.
  • Finally check our reviews to make sure it has a good line feed mechanism.
