There’s more to mowing the lawn than many people think.
Now, there are varying opinions as to which is the best part of the may to mow the lawn.
Some experts say it matters, others say it doesn’t.
I’m on the side which believes it does matter. At least, if you care enough about your lawn to want to make it as healthy and as lush as possible.
The Best Times of Day to Mow the Lawn
This infographic by YourGreenPal explains perfectly when the best time of day to cut the grass;
Mid Morning: 8am – 10am
Mid-morning is one of the best times of day to cut the grass.
By 10am the morning dew or moisture from early irrigation should have evaporated and the grass can recover before the heat of the day sets in.
After 10am the temperature starts to rise which can cause further stress to your gass.
Plus, working when its hot isn’t much fun.
The only time mid-morning might not be the best time to mow is if you have a north-facing lawn. It might take a while for any dew to evaporate dies to shade being cast by your house.
In which case, choose the next best time.
Late Afternoon: 4pm – 6pm
Late afternoon, between 4pm – 6pm is also a good time to cut the grass.
The temperature is generally cooler so you don’t have to worry about the heating stressing the grass.
There’s also plenty of time for the grass to heal before nightfall and the onset of another dew.
The Worst Times of Day to Mow the Lawn
Just like there are the best times to mow, there are also the worst times.
It’s just as important to know when NOT to get the mower out so you can avoid causing any unnecessary damage or stress.
Early Morning: 6am – 8am
Early morning is the worst time of day to mow the lawn as morning due makes the grass wet.
Cutting wet grass is never recommended.
The grass tends to tear instead of slice and in the worst cases, you risk ripping chunks of grass from your lawn.
This can stress and weaken the grass making is susceptible to disease.
Plus, wet grass sticks to your mower which makes cleaning it harder work than it needs to be.
Midday: 2pm – 4pm
Midday is another time of day you should avoid.
While the sun is at its peak, your grass is busy photosynthesising, producing food and trying to keep hold of its moisture.
If you cut the grass now, you’ll almost hear it cry.
And again, pushing a heavy lawn mower around in the midday sun isn’t fun. Petrol mowers can overheat too.
Evenings: 7pm – 9pm
Mowing your lawn too late in the day is just as bad as mowing it too early.
Exposing freshly cut grass to overnight dew without giving it time to heal will open the door for fungal diseases.
A Couple of Caveats
Of course, all this depends on us having perfect weather, which let’s be honest, is rarely the case.
The reality is that weather conditions change and some days might be dry, overcast and relatively cool. In which it’s perfectly acceptable to cut the grass in the middle of the day.
Other times, it might rain all night and mowing at mid-morning might not be possible.
So use common sense and adapt your mowing schedule to the conditions.
There are good and bad times of day to mow your lawn but they might not always apply, depending on the weather.
However, as long as you understand why these rules matter you can make a better judgement as to when might be the best time on any given day.
Again, some people don’t think it matters at all but I do, for all of the reasons I’ve mentioned above.
Whatever time of day you cut the grass, make sure the blade on your lawn mower is sharp and cuts cleanly. Even the best lawn mowers can ruin a lawn if the blade is blunt.
