Sedgehammer herbicide is a water dispersable granule formulation used to kill and remove Nutgrass and Mullumbimby couch without affecting your lawn. Sedgehammer can be safely used on lawn varieties including bent grass, buffalo, couch, kikuyu, perennial ryegrass, QLD Blue couch and Tall fescue.
We have tried a lot of products, including Sempra, but none have killed the nutgrass in our lawn as well as the Amgrow Sledgehammer has. Sledgehammer is by far the best product to get rid of nutgrass and the most economical.
