It’s spring and you’ve probably started mowing your lawn again after a long and cold winter.

Whether you’re adding grass seed to help it recover or it survived pretty well, the better weather will no doubt have your garden looking greener with the grass growing longer.

But do you know the best time of day to mow your lawn? Mowing at the wrong time can cause damage to the grass and increase the risk of disease, according to an expert.



What is the best time of day to mow your lawn?

Chris McIlroy at The Grass People says the optimum time to get your mower out is around 10am or between 4pm and 6pm.

He explained: “At this time of year, grass can be quite dewy in the morning. If you cut while it’s still wet, you will just drag and rip the blades rather than cutting them cleanly which can lead to disease. It will also give you an undesirable finish.

“This is why we would advise not to cut too early in the morning and instead wait until the sun has had time to dry the dew off.

“If you really can’t wait, a quick hack is to drag a hose across the grass to get rid of much of the dew. It will then dry much quicker.

If you don’t have time to tend to your garden in the morning, your best bet is to give it some TLC in the late afternoon, according to Chris.

He continued: “Alternatively, you could look to cut in the late afternoon, between around 4pm and 6pm.

“This avoids the hottest part of the day when your lawn could get stressed by the heat.

“It also ensures the grass has time to recover before nightfall, when the cold and damp weather could expose your freshly cut blades to fungal growth.”

How often should you mow your lawn in spring?

During the spring months, you should aim to mow your grass once a week, increasing this to around twice a week during the summer months.

Chris said: “Little and often is a good rule for cutting at this time of year. During the spring months, you ideally want to get your mower out every seven to 10 days, removing around one-third of the length each time.

“If you find your grass is looking bare and patchy, it might be because you are waiting too long to trim your blades and then cutting it too low when you do.”
