Why mowing height matters more than you think

If you’ve ever pushed a mower across your yard and thought, “How short should I go this time?” I’ve got some news for you: that decision might be more important than you realize. Yep, mowing height isn’t just about making your lawn look neat. It's about giving your grass the best chance to shine and stay healthy. Let’s dig into why getting it right can make all the difference for your patch of green (and maybe save you a heap of effort in the long run).

The Secret Life of Your Lawn

Okay, imagine your lawn as a living, breathing community. Each blade of grass is working hard to grow, soak up the sun, and protect the soil beneath. When you mow too short—what some folks call “scalping”—you’re essentially chopping off its energy factory. Grass uses its blades to gather sunlight, and without enough of them, it struggles to photosynthesize. In other words, you’re starving it. Sad, right?

On top of that, short grass leaves the soil exposed, which can invite the sun to dry it out. Dry soil leads to weeds, and let’s face it: no one wants to karate battle with dandelions all summer. The right mowing height acts like sunscreen and a shaded umbrella rolled into one for your lawn. Protect the soil, and you protect your lawn’s health.

Less Work Equals More Perks

If you’re thinking, “But I want my lawn nice and short so I don’t have to mow as often,” I hear you. That sounds like a solid plan—except it’s actually the opposite of how a happy lawn works. Cutting grass too short stresses it out and leaves it vulnerable to pests, diseases, and weeds. Translation? You’ll end up doing more work, not less. Spraying for weeds, patching bald spots, and hoping grass will bounce back—those aren’t on anyone’s weekend wish list.

By leaving grass a bit longer (typically around 6-8 centimeters, depending on the type), you’ll actually wind up mowing a lot less. Longer grass grows more naturally, and healthy lawns are way better at fending off invaders like weeds and pests. It’s lawn care for the efficient—and let’s be real, we all love a good shortcut that doesn’t compromise results.

What’s the Best Height for Your Lawn?

Alright, here’s where the rubber hits the road (or, you know, where the mower hits the grass). Grass types aren’t one-size-fits-all, and choosing the perfect mowing height depends on the kind of lawn you have. If you’re unsure, you’re not alone—lots of homeowners don’t even know the name of their grass. But figuring it out is easier than you think (ask someone at your local garden center—you know, the ones who sell the seeds).

  • Couch Grass: This resilient lawn buddy thrives when mowed to about 1.5 - 2.5 centimeters. Go too short, though, and it might retaliate by turning patchy.
  • Kikuyu: Known for being low maintenance, Kikuyu likes a cut around the 3-5 centimeter mark. Too much off the top, and it may look sulky and bare.
  • Buffalo Grass: Keep the mower around the 5-6 centimeter range for this soft, family-friendly type. Its wide blades love a little extra length for that lush effect.

If you’re still confused—or just want a second opinion—pop by your local garden center to chat. Pro tip: always avoid chopping more than a third of the blade length at once. Grass gets grumpy if you hit it with a super-short style all at once. Slow and steady wins the race!

The Long Game for a Strong Lawn

Besides looking gorgeous, letting your lawn grow to its optimal height helps build deeper roots. Deep roots mean your grass can reach water further down in the soil, reducing both watering needs and drought stress. Winning! Plus, longer grass also shades out sunlight-hogging weeds like crabgrass, giving your lawn more of the scenic spotlight.

And don’t forget the environment: the healthier your lawn, the less you’ll need fertilisers, herbicides, and extra water. So, not only are you creating your little patch of paradise, but you’re also doing your part to save the planet—all from mowing a bit higher. Who knew your mower could have superhero energy?
