Mowing in the Cooler Months

Mowing in the Cooler Months

As we enter the cooler months and temperatures start to drop, it’s normal for your lawn to grow at a much slower rate. When soil temperatures drop below 14℃ your grass will enter dormancy which allows it to conserve energy.

To help your lawn adapt to the cooler climate you should adjust the height of your lawn mower, leaving the grass longer to create a thicker canopy. This will allow for better photosynthesis, allowing your lawn to absorb more sunlight and nutrients.

Keeping your lawn that little bit longer throughout winter will help the grass leaves to retain their colour. Longer grass will also make it harder for weeds to push through. The most important thing is to prepare your lawn before winter sets in, making sure it’s healthy as you head into the colder months. Adjusting your mower height will help to prepare your lawn for the cold and frost as well as assisting it to recover quickly when springtime comes around.

The Ideal Length

Depending on your turf type, you should only need to mow your lawn every few weeks during winter. Aim to keep your lawn at around 4-5cm long. Longer than this and you will prevent sunlight from properly penetrating the grass profile and may cause scalping when it’s mowed again. Scalping will cause browning of your lawn, which can make it susceptible to disease.

As tempting as it may seem, resist the urge to cut your lawn really low early in winter in an attempt to avoid mowing for longer. Cutting it too low will leave your lawn more susceptible to winter weeds and frost and will create more work for you when spring comes around again.
