Why is Nutgrass so hard to kill?
There are several reasons why nutgrass is difficult to kill:
- It is not a broadleaf weed and the normal bindii and clover killers won’t work
- It has glossy leaves, this means large droplets containing herbicides can roll straight across the leaf and onto the ground, preventing absorption
- It can be persist and knows when it’s being attacked, cutting off the top and regrowing from the tuber.
- Herbicides that do control it come in a wettable granular formulation as opposed the liquid formulations we are used to, that means a little extra mixing
How to kill nutgrass
The secrets to killing nutgrass is to overcome some of the obstacles above.
- Get the right herbicide for the job, Tempra is selective in nature, killing without harming your lawn.
- Use a surfactant like Spreadwet to ensure the product sticks to the leaf and doesn’t roll off. Wet Out works by reducing the surface tension of the spray droplet.
- Re-application will likely be required and is best when the weed has recently emerged and is still small.
- Ensure the wettable granular is properly dissolved and evenly distributed within the tank This can be done by mixing the product in a small amount of water before adding it to the tank or by shaking the tank vigorously.

With our product recommendations we like to help you get the best results and reduce the likelihood of having to deal with the problem again. It will likely require repeat applications in bad infestations but we can do something to reduce the spread of the weed and reduce any future infestations.
As you may know by now Nutgrass is a sedge and sedges love water so the best way to prevent it from coming back is to reduce the water in the affected area. Sedges being present is generally an indicator that the soil is compacted and wet.
So let’s resolve those problems. This doesn’t mean drying your turf out, it just means ensuring it’s not constantly wet. Start by identifying why this area is becoming wet. Common reasons include:
- Poor water penetration, creating a runoff to this low area
- Shaded areas receiving too much water
- La Nina in 2022 and 2023 has been an incredible force in creating an increase in sedges
The ways to resolve this include:
- Aeration of soil
- Use of a wetting agent to increase water penetration
- Improve drainage

Q & A
How do I get the best results?
Nutgrass is not actually a grass, it’s a sedge, these are water loving and glossy. You can improve results by drying out this part of your lawn as well as adding a surfactant such as Wet-out when mixing the herbicide, simply add 12ml to 10L water.
How much water should I apply to water in?
Watering or rainfall is not recommended within a day of application..
Is this safe for all turf types?
It is safe for all turf types. Please read the label directions before applying.
How long before I see results?
Tempra contains halosulfuron-methyl, the results from this active ingredient are slow. Results are generally evident within 7-10 days. A total kill will take between 4-6 weeks dependent on weather conditions.
Is there anything else I should do after applying a herbicide?
An application of fertiliser is recommended to help the lawn fill in this area. Sedges are a symptom of wet areas, an application of Lawn Play Aquaturf will be helpful to manage water control and efforts should be made to reduce the amount of water held in the soil by adding drainage or coring.
