Do you need a product like spreadwet to add to the nut grass killer? How much is 1.3grms, is there a measurement scoop? Veronica Hassinen asked on 17 February 2025

Hey Veronica,
Yes, it's recommended to use a non-ionic surfactant with Nutgrass Killer. This helps improve the spreading and penetrating properties of the herbicide, ensuring better coverage and uptake by the weed.

The box comes with a small measuring scoop to measure the 1.3g needed.

Hi will this damage my Sir Walter grass which is full of nut grass. Adrian asked on 8 February 2025

Hey Adrian,
Superway's Nutgrass Killer is designed to be safe for lawns, targeting nutgrass and other unwanted weeds without harming the grass. It uses halosulfuron-methyl as its active ingredient, which is effective in controlling nutgrass and Mullumbimby couch without damaging common lawn types. However, it's always advisable to follow the product instructions carefully and ensure the product is applied correctly to avoid any potential damage to your Sir Walter Buffalo grass. Test a small patch of lawn first to see the reaction before applying to the rest of the lawn.

Can I use this product round my Sasanqua Camellias and in the grass near them? Philippa asked on 23 November 2024

Hey Philippa,
Yes, Superway's Nutgrass Killer can be used around Sasanqua Camellias and in the grass near them, as it is a selective herbicide targeting nutgrass and certain other weeds without harming most broadleaf plants and grasses. However, care should be taken to avoid direct contact with the foliage or roots of your camellias during application. Use a targeted spray technique to minimize drift and apply according to the label's instructions for safe use.
