If you want to get rid of weeds without harming grass, then be sure to buy a selective weed killer. This herbicide is designed to only target weeds, making it a safe bet for your lawn. So before you buy any weed killer, read its product label thoroughly. Check whether it’s recommended for lawns with beneficial plants and grass. If these details aren’t available, then go through the list of ingredients. Look for ingredients like quinclorac and fenoxaprop that are capable of killing grass weeds selectively.
