You’ll never forget your first mow. That’s what they say – if you don’t do it properly!

"You’ll never forget your first mow" - that’s what they say if you don’t do it properly! You should allow your grass to grow to a specific height before considering cutting it. And by doing so, you won't damage it and you won't stunt its growth.

Allowing your grass to grow to the ideal height before mowing is essential to aid its future growth. Why? Because if you mow it too short, you might damage it and it might take a long time to grow back properly. For this reason, it's crucial to know when to cut grass.

But it’s not all serious. If you know the first mowing height and the recommended mowing height for your mixture going forward, everything else will be easy. Mowing and grass cutting are easy but be aware that they can change throughout the year!

4 First Grass Cut / Mow Tips

  • Wait until your grass lawn is it is 5-7cm before mowing
  • Take away the cuttings (why not add them to a compost heap)
  • Let the grass settle for a week or two after your first cut
  • Going forward mow at the recommended height (per product)

What Height Should Your Grass be Before Cutting?

We recommend that the ideal height of your grass should be around 5 – 7cm before you cut it, and this goes for all our grass seed mixtures. This is simply because if the grass has been able to reach this height, it is viable, growing well and can be cut. If it isn’t reaching this height, then it either isn’t established, or something is stunting its growth.

5-7cm is the Perfect Height for Your Garden's First Mow

If your new lawn or overseeded lawn has reached the golden heights of 5-7cm then it’s time to give it its first mow. Set your lawn mower to the highest setting. The aim is to give the grass a trim and not cut too far down the grass blades.

Tidy Up After Cutting to Enhance Growth

Ensure to remove all the clippings after you have mown your lawn. If you leave them on a newly seeded lawn, you could be contributing to thatch which would undo all your hard work. In addition, dead grass sitting dormant on top of your lawn stops much-needed sunlight from getting to your new grass.

Most Grass Types Have Different Tolerances for Mowing Height

Now, going forward, your recommended mowing height will change. Different types of grass seeds have varying tolerances for how close they can be mowed. 

For example, the fescues in our STATEMENT: Front Lawn mix will tolerate close mowing, this is because they are of a finer leafed variety, and close mowing helps to achieve the ornamental look that fescues are known for. 

The recommended mowing height for STATEMENT: Front Lawn is 10-20mm. For our ever-popular SUPERSTAR: Back Lawn the recommended mowing height is 20-40mm. This height is double the recommended mowing height for STATEMENT: Front Lawn. Whilst this doesn’t entirely mean that the mix won’t withstand closer mowing, it shows that this mix is not intended to be for an ornamental lawn. But likewise, it will perform well at a slightly higher height.

We have recommended mowing heights for all our mixes which can be easily found in the ‘Usage guide’ tab of each of our products. And if you haven’t got a ruler handy, each of our grass seed mixtures comes with an instructional card that already has a ruler on it!

So contrary to popular belief, the first isn’t the deepest, it might just be the easiest!
