Will Sedgehammer Herbicide harm my roses?

I have nutgrass growing in my rose garden, & I want to get grid of it. If I spray the nutgrass with Sedgehammer, will it also affect my roses.


Sedgehammer Herbicide kills nutsedge without injury to listed turfgrasses. You can apply Sedgehammer at specified rates as a post-directed spray around established woody ornamental species in landscaped areas. This would be safe to use around your roses only if you are not spraying them directly and they are well-established, woody plants.  You should make direct treatments to the nutsedge only as it cannot be used as an over-the-top spray to desirable flowers.
