A tree pruner has a telescopic pole that enables you to cut branches easily from a distance of 6 or 7m from the ground. Most pruners can cut through 25mm diameter branches, but for anything larger, or for dead wood, you'll need a pruning saw, which is attached to the pruning pole. These sometimes come with the pruner, or are otherwise sold separately.

Tree pruning is obviously much safer with your feet on the ground, but there are a few things to remember - wear goggles to protect your eyes from any falling debris, and, if possible, a safety hat too. And don't stand directly underneath the branch you are removing. Finally, if your neighbour's tree is simply shading, rather than overhanging your garden, you'll need to ask their permission before you start chopping. If their tree is overhanging your garden you can cut it back to the boundary, but it's polite to let them know first, and you must offer to return any fruit or branches that you remove.

To help you choose the right set to suit your budget and gardening demands, the Gardening Which? team have been busy testing tree pruners to bring you the pick of the bunch. After carrying out laboratory tests on eight tree pruners, Gardening Which? then asked 24 amateur gardeners to trial our selection, rating them for performance and ease of use when cutting. Below are the three that came out on top.
