How to mow your lawn

Only cut your lawn when the soil is warm – let it rest in the winter

Timing is everything when it comes to mowing your lawn. The best advice is to avoid cutting your lawn between October and 'First Cut Sunday' – usually the first weekend in April (but can also be in early March depending on your region). This is when the soil is warmed and the grass has reawakened from its dormancy. 

The time in-between allows the lawn to rest during the winter period, when there's very little growth. It also means you can avoid cutting during wet weather or frosty conditions, which can damage your lawn's roots.

But if winter has passed and you're raring to go, then check out these top tips first:

  1. Make sure your lawn mower has sharp blades and is free from debris. You can remove and sharpen the blades yourself or look for a local company online to do it for you.
  2. Set the height of your mower to the length you want to cut the grass. If you don't know how to do this, check the manufacturer's instructions. There are normally levels on each wheel that allow you to move the body of the mower, and therefore the blades, up or down.
  3. If your lawn has got a bit overgrown, resist the temptation to set your mower to its lowest setting as you'll just 'scalp' the lawn, which damages the blades and can lead to weeds. Instead, follow the rule of thirds and never cut more than a third of the blades off in one go. This will encourage fresh, healthy growth but start to neaten things up.
  4. Move any pots or plants out of the way. That goes for children's toys or games, too (don't forget we have lots of lovely ideas in our garden activities for kids guide).
  5. Mow around the edge of your lawn first and then mow the body of the lawn up and down in straight lines. Don't walk too quickly or you won't get an even cut.

How to mow your lawn with stripes

Sure, a freshly mown lawn is one (very lovely) thing, but a striped freshly mown lawn? Well, that just takes things to a whole new level. Paul Hicks, Product and Marketing Manager at STIHL shares his expert advice for achieving this gorgeous effect.

'To create a beautifully striped lawn you basically need two things,' he says. 'A healthy lawn and a lawn mower with a rear roller.'

'A healthy lawn requires proper cutting, watering, fertilising and aerating on a regular basis, with an understanding of the right time to do each of these things.' We can help you on your way with our spring lawn care tips, and you might want to check out our best garden sprinklers, too.

Once you've got your lawn looking luscious, it's time to get striping. 'Lawn stripes are created by the roller pushing the blades of grass forwards and pressing them down, as the mower passes over,' says Paul. 'By always following the same stripe each time you mow, you will increase the definition of the stripes, as more of the grass will be pushed over.'

'The actual stripe effect is caused by light reflecting off the grass,' he explains. 'The lighter shade comes from the blades of grass facing away from you and the darker shade is caused by shadows in the blades of grass facing you.'

Check out Paul Hicks from STIHL's top tips for the best striped lawn on the block:

  1. Don’t cut your lawn too short. This will impact the stripes, so Paul suggests to go no shorter than 30mm.
  2. To keep stripes looking tip-top, it's best to mow at least once a week.
  3. Get creative! 'The beautiful thing about striping a lawn, is that you don’t have to walk in a straight line for the effect to work. You can create just about any pattern you like, as long as you continue to bend the grasses in opposite directions.' Check out our lawn decoration ideas for more artistic inspiration.

Keep the edges of your lawn looking neat

There's no point getting the main bulk of your lawn trimmed to perfection if messy edges let it down. If the edges are generally uneven, you may need to re-cut them with a half-moon edging iron or, if you don't have one, a sharp spade. 

Once you've got a neat shape, use the best strimmer or a pair of sharp, long shears to keep those rogue blades in check. And why not go the extra mile and install some of our modern edging ideas, too? They're the perfect finishing touch to keep a plot looking neat.

How often should you mow your lawn?

During summer, trim your lawn as often as it needs. So, although it might be tempting, don't make mowing every Sunday be a concrete part of your routine. Instead, mow when the grass is long enough for you to need to trim it down by a third. This will usually be once a week.

Always avoid mowing on really hot, dry days as you'll expose the roots of the grass to the sun and cause more damage than good.

How should I do the first mow of the year?

The first mow of the year is always an exciting one, as it'll instantly make your plot feel smart and summer-ready. But what's the best way to do it? Paul Hicks from STIHL shares his expert tips:

  1. 'When cutting your lawn for the first time, it's likely to look a bit unloved and overgrown, so be sure to clear the area of any leaves, sticks and other debris that may interfere with mowing or could damage the mower blade.'
  2. Paul also recommends following the one third rule when cutting for the first time. 'Never cut more than a third of the blade of grass in one go,' he says. This is because cutting it too short, too fast can damage the turf and lead to disease or weed infestation. Over the next few mows, you can gradually reduce the length to your liking.
  3. 'All lawns and gardens have different needs, so it is important that you take this into account when choosing a tool for the job,' Paul adds. 'The STIHL RMA 235 is a great choice for homeowners with medium sized gardens up to 300m2. This compact mower, which is part of STIHL’s cordless range, is quiet, easy to manoeuvre and gives a brilliant quality cut, time after time.'

If you're regrowing patches of your lawn from seed, be especially careful not to damage it. First-season grass from seed is especially tender, so wait until it's at least three inches long before trimming. And remember – only take a third off at a time.

Extra lawn mowing tips:

  1. Splash on apple cider vinegar instead of weed killer: it's just as effective and more eco-friendly
  2. Wear your stilettos (yes really!) – the heels will help puncture thick grass and let nutrients penetrate the soil
  3. Put rusty nails in your watering can – grass needs iron to grow, and the nails will release iron into the water
