When to cut your grass after winter

Like with the advice for the final time to cut grass before winter, the general advice revolves around when the frost starts and ends. 'As a rule of thumb, we recommend waiting until temperatures are consistently above 8 degrees before you think about mowing your lawn,' say the experts at The Grass People.

So the optimum time to trim your lawn ideas will depend on where you live. 'The south of England should hopefully start to see favourable conditions at the beginning of March, whereas those in the north of Scotland might have to wait quite a bit longer.'

The best way to tell whether or not it's a good idea to get the lawn mower out is to check the ground regularly for signs of frost. It's best to look at the grass early on in the morning, when it's most likely to show frost from the night.

'It’s best to wait until frosts have passed as these can damage grass blades and increase disease,' explains Leigh Barnes, Jacksons Fencing. 'When you cut your grass will also be dependent on weather conditions as if there has been lots of rain, the ground will be too wet, so wait until there is a dry spell to do your first cut, and without any morning dew.'

When temperatures are below 8 degrees, the grass will be in a state of dormancy and you won't see much growth. So if your grass has started looking longer than it was before, this is a sign that the temperature has increased enough for the grass to be cut again. 

Waiting until March to cut your grass after winter also gives it a chance to grow. This will work in your favour, as most experts would agree that you should wait until your grass is around 7cm long before cutting for the first time. This will ensure that your grass is strong and sturdy enough to deal with the stress of being cut. 

Ultimately, this will improve the health of your lawn as the year progresses.

In most cases, February is too early to mow the lawn, because temperatures aren't consistently warm enough throughout the month. The key word to remember here is consistently; you may have a couple of warm days in February, but then experience colder weather again after. This means that if you jump in and mow the lawn at the first sign of sunshine, the cut grass won't be able to withstand the frost and will quickly start to brown.

'In parts of the UK right now, there are still days in the next two weeks that are scheduled to get below freezing, meaning that frost is likely to still be prevalent,' says  Rian Habergham, Gardening Expert, Leisure Bench

'Once this has finally cleared and the frost looks like it's gone for good, you should think about starting to mow your lawn. This is looking more and more like mid to late March at the moment, however, this could still change depending on weather conditions.'

So, it’s best to just keep an eye on the weather forecast and play this garden task by ear. When you’re happy that the temperature is consistently warm, you can finally whip out the lawn mower and give your grass a much-needed haircut after the winter months.
