A guide to cutting long grass without killing it

It is crucial to follow the proper method of cutting 1/3rd of your overgrown lawn’s height at a time to keep it healthy. If you cut too much at once, you can end up damaging the roots, spreading weeds, and losing your beautiful lawn.

Before you start mowing, make sure you have checked your yard for any obstacles that could impact the mow. Grab your mowing tools that could include a blade trimmer and rake. Prepare your lawnmower and make sure that you are wearing protective clothing and safety equipment.

  1. Measure and cut one-third of the grass length
Should I cut my long grass1/3 at a time?

The first mow of your lawn when the grass has grown very long should only cut 1/3rd of the grass length. Lots of people make the mistake of just chopping the grass right down immediately. But this, as we’ve mentioned, damages the roots and can end up clogging your lawnmower.

To measure the grass height, you can use a regular ruler. A clear, plastic one can make it easier to distinguish the grass length. Measure your grass with the ruler and figure out what 1/3rd of the length is. For example, if your grass is 30cm high you would need to cut off 10cm because it is 1/3rd of the length.

Adjust your lawnmower height so that it will only cut off 1/3rd of the grass height you want. Then mow away! Try to mow your long grass between 8am and 10am. This is because you will need to give it time to recover before nightfall and before your next mow to protect its health.

Let the grass grow by a centimetre before you make the second cut.

  1. Cut the grass gradually until it is 5cm tall

After a week, your grass will be ready to be cut again. The second time around you should only take another third off the grass height. Leave it to recover and grow a centimetre again before making your third cut. This will also be 1/3rd of however long your grass is now. Repeat this method of cutting 1/3rd at a time until your grass is around 5cm high.

  1. The final cut to then maintain your grass

A good height for your lawn to both appear and be healthy is around 4cm, so this final cut will be 1cm. This is to take your lawn down that last little touch from the 5cm height that you gradually worked your way down to. After this, it is good to not let your grass grow higher than 5.5cm to be able to cut it without damage. Cutting long grass down without killing it is a gradual process. But if you do your best to keep on top of your mowing schedule, your lawn will stay healthy and beautiful! Remember, too, that the recommended mowing rule is once a week.

Tips for preparing your overgrown lawn

Now that you know how to cut long grass without killing it, you must know how to prepare your lawn before making any cuts. Here are some of the top tips to follow that will make your cutting process easier:

  1. Always sharpen your lawnmower blades and test your mower

Whatever blades you are using to cut the lawn, make sure that you sharpen them before use. Trying to cut your overgrown lawn with blunt blades will result in completely damaging your lawn and potentially the mower.

You need to also check if your lawnmower is in optimal working condition. If your equipment is not in the proper shape, it can affect the health of your lawn. Give the lawnmower a test run on a small patch of grass in case the lawnmower keeps stopping or some other issue arises. This way you can identify any problems before harming your grass. This way you can be sure not to extend the process of getting your healthy lawn back!

  1. Keep protective clothing on to mow

Your safety must be your top priority when cutting your lawn. That is why you should have protective clothing. These include:

Once you’re all kitted up, you can focus on helping your overgrown lawn get back to its prime state!

  1. Inspect your lawn for hidden debris
Pause often when mowing long grass

Always inspect your lawn before beginning the cutting process. There could be fallen tree branches, debris, rocks, and other items hidden in the overgrown grass. If you don’t remove these items, your mower or other equipment will suffer damage and pose a threat to your safety. Do a walk around the yard and check every area that the grass is covering just to be sure that nothing will hinder the cutting process. You’re better off doing this to guarantee your safety and reduce the risk of ruining your lawn.

  1. Pause frequently when cutting long grass

Cutting an overgrown lawn can be a tedious process, especially if your grass is super tall. That is why it is crucial to pause frequently as you cut the grass. If you don’t stop often, you could overheat your lawnmower and end up breaking it. Plus, you can make sure that the grass isn’t getting caught in the blades or anywhere else in the mower.

  1. Keep children and pets away

It is best to keep any children and pets away from the lawn when you’re cutting overgrown grass. This means you know where they are and that you won’t accidentally run into them. It keeps them safe. You should make sure to check for any other garden creatures like snakes before mowing too. If you come across an animal like this, have it removed before you cut your grass.

It’s always a good idea to have your lawnmower serviced, especially if it hasn’t been used for a while. Have you considered investing in a riding mower? Find out if a riding mower is worth it! For quality gardening tools, check out our garden section at Canberra Diamond Blade Suppliers!
