When Is It the Best Time to Mow the Lawn?

Grass
One of the most common questions we hear is "when is it the best time to mow the lawn?" it may seem straightforward, but timing your mowing correctly is crucial for encouraging strong growth, preventing any damage, and keeping your grass looking green and healthy all year round.


Spring is usually the best time to start mowing. This is when your lawn is waking up from the winter dormancy, the grass begins growing activley and can handle the stress of being cut. It is important to understand how mowing works across all seasons, as cutting at the wrong time or in the wrong way can set your lawn back significantly. 

Mowing a newly seeded lawn

If you have sown some new grass seed, patience is key! Cutting too early, or cutting it too short can undo weeks of hard work. Wait until the grass reaches around 203 inches before giving it a light trim. At this stage, only take the tips off, about an inch or so, leaving plenty of leafy growth behind to keep the plant nice and healthy. 

Continue with light cuts as the lawn grows back to that 2-3 inch mark, until it is well established. Over time you can gradually reduce the cutting height. Remember, newly seeded lawns may still have some seeds germinating weeks later, so allow time for thickness and coverage to develop.

Mowing an established lawn in spring

Spring is the best time to mow your lawn as the grass is activley Growing again. aim to cut when the blades reach around 2-3 inches, as you would with a newly seeded lawn. This shows the lawn is healthy enough to handle mowing. Avoid cutting too low too soon, as scalping the grass can weaken it and delay its growth. 

Spring is also the perfect time to feed your lawn and support its recovery from winter. For best results use our Ultimate Spring/Summer Lawn Fertiliser, to ensure your lawn gets the nutrients it needs to grow thicker and greener.

Why Summer, Autumn and Winter are less ideal to mow in

Whilst spring is the best time, lawns donw stop growing after the first cut. youshould still mow through the summer, autumn, and occasionally winter, but here is why those seasons come with extra challenges:

Summer: The hot, dry weather will already be providing stress to your grass, cutting too short in the dry seasons can cause brown patches and die back. During heatwaves, mow ledd frequently and keep the mower blades higher to prevent this. Consider using our Hydrate Plus Wetting Agent to help water penetrate dry soil and reduce the stress.

Autumn: Growth is begining to slow down at this point, but you may still need to do the occasional mow. Keep these cuts higher and less frequent to avoid weakening the grass before heading into winter. Autumn is a great time to apply our Autumn/Winter Fertiliser to strengthen roots and give your lawn the nutrients it needs to survive the winter. 

Winter: In cold and frosty weather avoid mowing all together, as the grass will be dormant and easily damaged. If the winter is mild and you are experiencing ongoing growth, mow very lightly and infrequently, keeping your blades high.

This approach will ensure the mowing you are doing will support your lawns health without giving it undeeded stress at the wrong times of year.
