The best mulching lawn mowers

Six of the best lawn mowers that save time by mulching - recycling clippings - as you mow

When mowing your lawn it’s well worth considering the range of benefits a mulching mower can have on the health of your green space. Instead of simply cutting the grass and disposing of the clippings, a mulching lawn mower produces a finer cut before pushing the loose grass back into the surface of your lawn. Here it will decompose, releasing nitrogen and other nutrients into the soil.

As grass is largely made up of water this means the lawn will require less watering and should grow to be healthier and greener. As well as saving you time, mulching the grass instead of collecting and disposing of the clippings elsewhere is also better for the environment.

What is mulching power?

Mulching works with the help of a purpose-built blade or mower add-on that cuts the grass more finely than a regular lawn mower. If the mower is not powerful enough to effectively chop the grass to a fine mulch and push it into the ground, this can create clumps on the lawn which can cause damage to the plants beneath.

We have picked out six of the best mulching mowers that will save you time and ensure you get the best mulching as you mow.
