Garden question - grass killer in flower beds?

[Deleted]

So, I spent 4+ hours yesterday removing all the weeds and grass from my garden. I hurt today.

That's done, but now I have the flower beds alongside my house to do. I'm not doing them today, hopefully next week though. There aren't quite as many weeds, but a lot of grass has grown into the flower areas.

If I buy a grass killer and then leave the grass there but just put mulch over it, that will work, right? I don't want to have to rip up a ton of grass again because it is hard and takes forever and I'm limited on time the next 4 weekends in a row.

I know I could ask a garden store but if anyone has experience with this and could help me, I'll order some grass killer in Amazon prime and avoid having to go to the store again

That's what I've done. The grass turned yellow and died within about 5 days, then I covered it with mulch.

It has not been my experience that weedkillers are safe for flowers. When I was a teen I did some accidental flowercide
