Bermuda, crab grass … I was brought up calling it wire grass, all the same basic stuff from what I can tell…. I’ve been battling it since I started gardening 37 years ago …
I’ve tried the cardboard, the plastic, the fabric (it loves the fabric something to grab hold of) …. Mulch before the above and after, till and till again, spend hours going through each square inch of soil by hand getting every sprig you can find … Pray over it, cuss it, accuse it and finally just admire it, for it’s strength and persistence….
All you can do is dig it out when you see it, be vigilant and smile …..
Never put it in a compost pile even if you think its dead, it’s not…. Dry it out and burn it…
