13 tips for lawn mowing


Discover 13 tips for cutting grass effectively.


Whether you like it or not, mowing the lawn is one of the most essential tasks in the garden in spring and summer.

Keeping your lawn mowed encourages it to grow more densely, creating a lush appearance. Also, it prevents weeds from growing and makes the grass more durable. It can take quite a bit of time to cut the grass in the growing season, so making sure you do it right is important.

In order to keep your lawn looking its best, frequency of mowing, cutting heights, and lawn mower maintenance are important factors.


Here are our 13 tips for mowing your lawn effectively.

Keeping your lawn mowed encourages it to grow more densely, creating a lush appearance.


Ensure your mower is regularly serviced

 Mower maintenance

For a clean,
quality cut, have your mower serviced at the start of every growing season.
Blades that are chipped or blunt can bruise the grass and cause straw-coloured
dieback. Regularly clean your mower to prevent a build-up of clippings.


Reduce the lawn height by one third

Taking a third off grass height

When you mow your
lawn, aim to reduce it by one third – any more would cause the grass to lose
its health and vigour.


During spring, cut every two weeks

Spring lawn mowing

As the grass grows
more slowly in early spring, it needs to be cut less frequently. You can trim
it fortnightly until the weather warms up in late spring.


Late spring and summer, cut weekly

Mowing long and over-grown grass

Mowing less
frequently means you’ll have to cut more than one third of the grass’ height to
keep it neat. If growth rates peak in late spring, you may need to mow twice


Choosing the right height for grass cutting

Mowing a seed-producing lawn

It is best to keep
lawn grass between 2.5cm and 4cm tall. For patches that get a lot of wear and
are heavily used, leave them a little longer, say 4cm-5cm. It could be left
even longer, at 7cm-8cm, in the shade.


Cut at the appropriate height

Adapt the cutting
height to the weather and season. The blade should be raised a little at the
beginning and end of the season. When it’s hot and dry, raise the blade to let
the grass grow longer. By storing more moisture in the longer foliage, the
grass stays green longer and the soil is shaded.


Cut grass on drier days

When the ground is
sodden, a mower will smear and rut the soil, and wet grass clippings will clump
and smother the lawn below. Mow when the grass and soil beneath it are dry. For

Newly sown areas should be avoided

Mow newly sown
patches of lawn once the grass is 4cm tall, then cut the rest of the lawn along
with it. 


Cut grass creatively

With different
heights and stripes, mowing the lawn is an opportunity to get creative. Choose
a mower with a roller for a traditional striped finish. An area could be left
unmowed – a natural look that is great for wildlife. 


Spread the grass clippings on the lawn or compost them

Composting lawn clippings

Cuttings from grass
can be composted – just make sure they are mixed with plenty of carbon-rich
brown material to prevent slimy compost. The grass clippings are left on the
lawn in the summer to help retain moisture. 


Trim the lawn edges

Keeping lawn edges trimmed

Overgrown lawn
edges can make a well-kept garden look messy and untidy. Use a half moon tool
to re-cut the edges of your lawn every spring, and trim overhanging grass after


Think about riding mowers

Riding a ride-on lawn mower

You might want to invest in a ride-on
mower if you have a large lawn and want to minimize the amount of time you
spend mowing. Which type you choose depends on the size of your garden, the
terrain to be mowed, and of course, your budget.


Think about hiring a professional gardening service

Hiring a professional gardener

You might think hiring a gardener would be an expensive luxury, but you’d be surprised as to how cost effective they can be. From grass cutting to hedge trimming, a good gardener will be able to explain what your green space needs, and make a plan that suits your budget.
