What is Carpet Grass?

Carpet Grass is a turf type that mainly grows in tropical regions of Australia. It is often referred to as “tropical buffalo grass”. Like buffalo grass, it only grows and spreads by its above ground stolons and has a broad leaf. This turf type loves hot weather with regular rainfall and will grow well in low fertility areas.

Where Does Carpet Grass Grow?

This is a popular lawn option for tropical regions as it thrives in hot and humid weather. This grass best grows during the wet season when there is increased rainfall; however, it will often struggle during the dry season when rainfall is limited.

This turf type is only considered an issue when it has invaded another lawn type. This is mainly due to the broadleaf standing out when growing in a finer leaf grass like couch grass.

If you do find some unwelcomed Carpet Grass growing within your lawn, here’s our guide on removing it.

How Do I Remove Carpet Grass from Growing in Couch Grass?

If you have a green couch lawn (e.g. TifTuf Hybrid Bermuda, Santa Ana, Winter Green), a DSMA based product will be safe to use on couch lawns. However, won’t be safe for use on the Carpet Grass. Something like the David Grays Crabgrass and Clover Killer is ideal.

However, it is important to note that although these products may make it sick, they are not registered for full removal.

How Can I Remove Carpet Grass from Growing in Buffalo, Kikuyu and Zoysia Grass?

If it is growing within a buffalo, kikuyu or zoysia lawn, unfortunately removal options will be limited.

If only a small amount growing, the best and easiest way to remove it is by hand. Like buffalo, it won’t have a particularly strong root system, making hand removal easier.

If the area has become heavily infested and there is not much of the main lawn type growing in the selected area, you may want to consider returfing this section of grass. This will require you to spray out the invaded section of turf with a non-selective herbicide. Remove the old turf, and then install new rolls of the main lawn type. If you would like more information on how to patch up an area with new rolls of turf, please check out our blog here.

If there are only small areas where the invading grass is growing, another option will be to selectively apply a non-selective herbicide to the Carpet Grass, while avoiding applying it to the main lawn, as it will harm it also. We recommend using a small paint brush, a weed wand, or the Yates Zero Gel to help accurately apply it.
