Guide to Nullarbor Couch Grass

What it’s best for

Budget-friendly and versatile, Nullarbor Couch Grass is a high quality, fast-growing grass that loves the Queensland sun. It’s a fine-leafed, dense turf makes for a beautiful dark green lawn that feels great underfoot. It’s perfect for the south-east Queensland climate, thrives with careful maintenance and bounces back after high wear and tear. Nullarbor Couch is also ideal for full sun environments. It’s drought tolerant and grows in a range of soil types. However, its fine leaf blade means it’s not great at absorbing sunlight. So it does need between six and seven hours of full sunlight each day to thrive.

Who it’s best for

As long as you get six to seven hours of sun, Nullarbor Couch Grass is perfect for your backyard. It looks absolutely stunning. And it will tolerate high foot traffic from both people and animals. That makes it a popular choice for backyards with sports-loving children and pets but also for professional sports areas, like cricket and football grounds.

How to care for Nullarbor Couch

Nullarbor Couch Grass requires very little watering. In fact, your lawn will only need watering when it appears dry. It does however need a higher level of care and maintenance than some other types of grass. Because it grows a dense turf and continues to grow quickly, it will require mowing more often in the warmer months of the year. However, it can tolerate a lower mowing height than other grasses. During the warmer months of spring and summer, you’ll need to mow your Nullarbor Couch every five to seven days. This is so it does not start to grow where you don’t want it to. In cooler months, Nullarbor Couch goes into a dormant state. As the weather warms up again, it will start to grow again early. worker laying couch grass turf in a curved garden bed bordered by pebbles and a mulched garden bed on one side and paving on the other side


Like any turf, Nullarbor Couch can occasionally have challenges. To forestall these, and help your lawn to thrive, we suggest a seasonal (two to three times each year) application of a good, slow release fertiliser such as Lawn Solutions Premium Lawn Food. As Nullarbor Couch grows quickly, it can invade spaces adjacent to your thriving lawn, such as garden beds or between pavers. The best way to stop this happening is to maintain your regular mowing schedule, including lawn edging. Regular application of a herbicide such as Lawn Solutions Oxafert is a good idea. If it’s taken hold somewhere you don’t want it to be, you could carefully apply a glyphosate (such as Roundup, following the label instructions). The benefit of this spreading habit is that if you get any bare patches they’ll quickly grow over.

How to lay couch grass

To lay your Nullarbor Couch turf for the best results we suggest:
  • Prepare your turf bed with 50mm – 100mm of good quality underlay.
  • Be ready to lay your turf immediately after it’s been delivered, so it won’t dry out.
  • Once laid, apply Lawn Launcher to help your turf retain moisture.
  • Give your newly laid turf a good soaking for 10 to 14 days after installation to help it establish.
  • Wait to mow until your turf has established roots. For the first mow, go lightly to promote horizontal growth.
