How often should you really mow your lawn?

Most people mow their lawn whenever it looks long and they have a spare hour. That works, but if you want a genuinely healthy, green lawn, a little rhythm goes a long way. Here is how often you should really be mowing through the year in the West Midlands, and the common mistake that quietly ruins lawns.

Spring and summer: the growing season

From late spring through summer, grass grows fast. In the peak months a lawn really wants cutting about once a week. Leave it longer than that and you end up hacking off too much in one go, which stresses the grass and leaves it looking yellow and patchy.

Fortnightly is the realistic minimum in summer if you want it to stay neat. Any less often and you are always playing catch-up, fighting long grass instead of just topping a tidy lawn.

The one-third rule

This is the mistake almost everyone makes. Never cut off more than about a third of the grass height in a single mow. Scalp it shorter than that and you weaken the roots, invite weeds and moss, and leave it prone to drying out. If your lawn has got long, bring it down over two cuts a few days apart rather than one brutal one. Little and often beats rare and savage every time.

Autumn: ease off

As growth slows from September, you can stretch the gap between mows. Through autumn, once every two to three weeks is usually plenty. Keep going with the odd cut while the grass is still growing, and raise the cut height a little so the lawn goes into winter a touch longer and tougher.

Winter: mostly leave it alone

In winter the grass is barely growing, so it rarely needs cutting. Never mow when the lawn is frosty or waterlogged, you will do more harm than good and churn it up. The odd very light tidy on a dry, mild day is fine, but mostly winter is a rest.

Why "little and often" wins

A lawn cut regularly at the right height grows thicker, greens up better, and crowds out weeds and moss on its own. A lawn left to get long, then scalped, then left again, spends all year looking patchy and stressed. The rhythm matters more than the effort. This is exactly why a lot of people put their lawn on a regular round. The grass stays in that healthy sweet spot all season, and they never have to think about it.

The honest catch

Mowing weekly through summer is a commitment. Between work, kids, weather and everything else, the weekend it actually happens is rare. That is fine. If keeping the rhythm yourself is a hassle, that is precisely the thing worth handing off, so the lawn stays healthy whether or not you have a free Saturday. See lawn mowing.
