Winter Lawn Care

Keeping your turf happy during the cooler months

When the temperature starts to drop, it can be difficult to know what your lawn does (and doesn’t) need to keep it happy and healthy during the cold season.

To help ensure that your turf remains as green as ever, we have put together a little seasonal help to answer all the important questions.

If you want to learn even more about Winter Turfing, check out our guide here.

Frequently Asked Questions

How often do I water my turf in winter?

The short answer is… as often as it needs to be! 

Most turf varieties that thrive on the Sunshine Coast will continue to grow during the cooler months, however the low level of rain that falls in the region will generally be sufficient to keep your lawn happy. If it is a particularly dry winter though, a good watering every so often is recommended for all turf types.

How often do I fertilise during the winter months?

A good quality slow release fertiliser will contain all the nutrients your lawn needs, including potassium and iron, and will last for up to 12 weeks.

Provided you have fertilised in Autumn and have your lawn well prepared for winter, you will likely be looking at providing an additional treatment around July if your lawn is losing colour or strength.

Which fertiliser should I use during winter?

During winter, it is great to find a slow-release fertiliser that contains good amounts of iron. Iron helps to strengthen your grass and improve leaf colour, which is perfect when temperatures are cooler during the year.

Head to our Shop page for some fertiliser options currently available, and everything you need to know about Winter Fertilising can be found here.

How often do I mow my lawn during winter?

As a rough guide, you will only need to mow your lawn every couple of weeks during winter. This will differ depending on the turf variety you have - give Rosemount Turf a call if you require further assistance.

What length do I keep my lawn at during winter?

When it comes to mowing, it can be tricky to know when and how to mow once winter arrives. Your lawn won’t completely stop growing through the winter in Australia, it will just grow at a much slower rate. Once soil temperatures drop below 14°C, your grass will enter into a slower rate of growth to conserve energy, which is known as dormancy.

You can help your lawn adjust to the cooler temperatures by increasing the height of your lawn mower. Keeping the mowing height nice and high will give your lawn the best chance to absorb sunlight and nutrients, and a longer leaf will help block out weeds and help your lawn to retain its colour for longer. 

While we recommend you leave your lawn longer, make sure you don’t let it get too long either. Longer than 5-6cm and it will prevent sunlight from properly penetrating the grass profile and you may cause scalping when it comes to mowing again. Scalping will then leave browning of your lawn, which will leave it susceptible to disease and weeds.

Can you lay turf in winter?

Definitely! On the Sunshine Coast, it is possible to lay turf all year round, and there are a variety of turf types that can be used. We even wrote an article or two about it (find them here and here)!

How do I treat winter weeds?

Winter weeds, otherwise known as Wintergrass, can be a real pest that affects your lawn in a variety of ways. In order to get on top of winter weeds, it is best to invest in a good post emergent herbicide and hand pull any emerging weeds when you catch them.

Where possible, prevention is best. Applying a pre-emergent herbicide like Oxafert will help to stop Wintergrass before it even emerges from the soil. By acting with a combination of both pre- and post-emergent treatments you will get on top of the Wintergrass infestation a lot quicker and significantly reduce any existing Wintergrass seed bank that has developed within the soil over time.

What turf varieties are available to be laid during the winter months?

On the Sunshine Coast, a vast majority of turf varieties are available to be laid during winter - these include:

  • TifTuf Bermuda Turf.
  • Sir Walter DNA Certified Turf.
  • Sir Grange Zoysia Turf.
  • Empire Zoysia.

Some grasses do grow better in the winter months - the varieties can be found here - but everything you need to learn about laying turf in winter is here.

Is ColourGuard suitable for use during the winter months?

Absolutely! ColourGuard can be used all year round, but it works incredibly well for turf that is not thriving during the winter months (and is looking a little brown). More information regarding ColourGuard can be found here.

What lawn diseases should you look out for during winter?

In some areas, climate changes can unfortunately provide the ideal breeding ground for particular lawn diseases. Generally, these diseases develop due to excessive shade (learn more about shade in winter here), compacted soil, poor drainage and lack of sufficient lawn nutrition. 

In winter, some of these problems worsened due to shorter daylight hours and fungal disease issues can quickly develop. There are a few different lawn diseases and weeds that can rear their head when the temperature drops:

  1. Dollar Spot.
  2. Wintergrass.
  3. Bindii.
  4. Creeping Oxalis.

If you are struggling with lawn diseases or weeds, give Rosemount Turf a call and we can assist through every season!

How do you repair your lawn damaged by cold weather?

If your yard is suffering after the cold weather, there are a range of things that you can do to get it back up and running - this includes:

  1. Fertilising with a nitrate rich fertiliser.
  2. Re-turfing.
  3. De-thatching (Spring only).
