How Often To Water Couch Grass?
Couch grasses are known for their water efficiency. Once they are fully established, Couch grass should be watered every 7 – 10 day in summer and even less in other seasons.
Depending on how often it rains, you may not even need to water your Couch grass at all. Luckily, Nullabor Couch is quite drought resistant.
So, if water restrictions are in place, follow their guidelines and although the grass may brown slightly, it will become green quickly once it rains or you can water again.

How To Mow Couch Grass?
The optimum mowing height for Couch grasses is 15 – 25mm. However, Couch grass is particularly prone to scalping if you cut it too short in one mow.
To avoid scalping, you should only mow 1/3 of your grass blade length at a time and simply mow your Couch grass more frequently until it is the desired height. You should also avoid mowing your Couch lawn in winter if possible.

This makes them an excellent choice for high traffic areas such as sporting fields as they are quick repairing and need less frequent watering.
