You’ve just laid down your new lawn. Congrats! Installing fresh turf is a big step towards creating a healthy, attractive outdoor space. But with this milestone ticked off, many homeowners immediately ask the same question: when is the right time to start mowing your new lawn?
Mowing too early can damage young turf, disturb root development, and undo all the hard work you’ve just put in. Leave it too long, however, and the grass can become difficult to manage and stressed when it is finally cut.
The answer depends on several key factors, including:
The season your lawn was laid
The type of turf you’ve chosen
How quickly the roots establish into the soil
Fortunately, there are a few reliable principles that make this decision much easier.
Generally speaking, you’ll want to avoid mowing your lawn for at least the first 7 to 14 days of its life.
That’s because you need to give the lawn enough time for its roots to become established. On top of this, this timespan really only applies to the warmer seasons like summer. In winter, you could be waiting up to 6 weeks before the time is right to mow your lawn.
With that being said, how do you know when to mow your lawn? Here are some hints to help you answer that question.
Grass height is one of the most reliable indicators that your lawn is ready for its first mow. Once the turf reaches approximately 6cm in height, it’s usually strong enough to handle mowing without stress.
It’s also important not to let the grass grow much taller than this, especially for the first cut. Cutting overly long grass places unnecessary strain on the turf and can result in uneven mowing, scalping, or tearing of the young plants.
The goal of the first mow is not to dramatically shorten the lawn, but to encourage lateral growth and density.
Another simple test involves checking whether the turf has properly rooted into the soil.
After the appropriate waiting period for your season:
Gently grip a small section of turf
Try to lift it from the surface
If the turf lifts easily, the roots have not yet established and you should wait a bit longer.
If the turf stays firmly in place—or the blade of grass breaks before the turf lifts—this is a clear sign that the roots have taken hold. At this point, your lawn is ready for its first mow.
This test is especially important for avoiding damage during early mowing.
Now that you’re turf is ready to be mowed, there’s a few things you should know before you start and throughout the lifespan of your turf.
First off, make sure the blades on your mower are sharp. This will ensure a clean cut across each blade of grass, reducing the risk of disease and establishing a neat, clean appearance that will make your lawn stand out.
To sharpen your mower blades, you’ll need to remove the individual blades. Make sure you pull out the spark plug wire before you do this, so that you don’t accidentally start the motor.
Tip the mower on its side, with the air filter and carburettor side facing upwards, so that no oil or gas drips out. Mark each individual blade with some spray paint, so that you know which configuration to reinstall the blades in.
From there, remove the individual blades, and then use a file to sharpen both sides of each blade. Since mower blades are made from relatively soft steel, you’ll only need fewer than 50 strokes to make them sharp. Also, make sure you file in the direction of the original cutting angle.
Lastly, reinstall the blades in the same configuration in which you took them out. Make sure the blades are nice and flat and balanced. Unbalanced blades will cause vibration and reduce the effectiveness of their cutting.
To keep your lawn in pristine condition, only mow about 1/3 of the leaf. This reduces the amount of stress that’s placed on the lawn, allowing it to maintain a firm, consistent grasp on the deep roots.
Mow the grass too low, and you risk exposing the soil to the harsh, natural sunlight, and thereby encouraging the growth of weeds. This will make your life a lot harder, costing you precious time spent on pulling out those nasty strands.
Therefore, keep your lawn at a reasonable height during all seasons, while avoiding the temptation to chop the whole thing off.
The first mow is one of the most important steps in establishing a healthy lawn. Even when your turf is ready, mowing incorrectly at this stage can place unnecessary stress on the grass and slow root development. Following these best practices will help your new lawn transition smoothly into regular maintenance.
For the very first mow, always set your mower to its highest cutting height. The aim is to lightly trim the tips of the grass rather than significantly shorten it. This encourages lateral growth and thickening while allowing the roots to continue strengthening beneath the surface.
Avoid mowing wet grass, especially on a new lawn. Wet turf is more likely to tear rather than cut cleanly, and the added weight of the mower can cause rutting or turf movement. Dry conditions ensure a cleaner cut and reduce stress on the grass.
When mowing for the first time, move steadily in straight lines and avoid tight turns. Sharp pivots can twist or lift newly laid turf that is still settling into the soil. If you need to change direction, gently lift the mower or make wide turns.
A slower pace allows the mower blades to cut cleanly and evenly, especially on young grass. Rushing the first mow increases the risk of scalping, uneven cutting, or pulling at the turf before it is fully established.
For the initial mow, it’s often best to catch the clippings rather than mulching them back into the lawn. This reduces the chance of clippings smothering young grass and helps keep the surface clean while the lawn is still developing.
By taking extra care during the first mow, you set the foundation for a denser, healthier lawn that will handle regular mowing with ease as it matures.
Watering plays a critical role in helping new turf establish strong roots.
Immediately after installation:
Water the turf daily, sometimes up to four times per day depending on temperature and wind
Keep the soil consistently moist, not waterlogged
Prevent the turf from drying out at any point
Maintain this routine for the first 7 to 14 days, or until the turf has fully rooted and can no longer be lifted.
Once established, reduce watering frequency to around once per week, applying deeper watering each time. This encourages roots to grow deeper into the soil, improving drought tolerance and overall lawn resilience.
When you first lay down your turf, be sure to water it every day; sometimes as much as four times a day, depending on your climate. Doing so will keep the soil healthy and moist and prevent the turf from drying out.
Keep up this routine for at least the first 7 to 14 days, or until the turf has taken the root (i.e. you can no longer lift the turf). After this period, you’ll only really need to water your lawn about once per week.
This way, your lawn will be more drought tolerant, resulting in a better looking and performing lawn all year round.
