How do i put to death grass and stop it growing again?
Answers: We need a few more facts. Are you talking give or take a few a lawn you don't want or just the couch grass that invades flowerbeds? If it's the latter, you have need of to use a weedkiller although this is better done in very rash spring before your precious flowers come up. You can pull it up if you are an natural gardener but it just comes back so you enjoy to eradicate the source, usually a nearby lawn. If it's the sward you want to get rid of, removing the turf is the best way to stop it growing support. It's a fair bit of digging so hopefully you don't have 1/2 an acre!
