What is the best weed poison to use on tall grass in your garden?

I have this crabby grass in my garden with LONG roots, and it seems to connect and regrow another weed feet away from one another. It grows in my garden among my good plants. I HATE weeding. Any good sprays to get rid of it?

Roundup will kill anything it touches roots %26amp; all.



You can buy it premixed if you don't have a large area. If you have a lot to do get some of the concentrate %26amp; mix it in a garden sprayer.
