Nutsedge is a tough, stubborn weed, however, this product is listed to control it. If you have any other questions about our products, please contact us at 866-324-2647 for further assistance. **Q: Is Roundup 5003240 safe to use to kill grass that is inside/with flowers? Will flowers survive, and grass die?** A: Some plants survive, most die. Same with humans - Round Up causes cancer, but some people survive cancer. So the ball is in your court. **Q: Good for thistle down to the root in rockbeds? Does it eliminate weed pulling? Safe to use?** A: Not familiar with weed types. I've sprayed different weeds and grass in driveway cracks. Everything is dying. It's very handy to use, just push the button to Lock or Unlock to spray. The shield stops spray from blowing onto nearby plants. Marilyn ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product. *by M***E on Reviewed in the United States on 13 July 2024* Flow control.
