This crap sprouts up everywhere. I pull it when i see it and have used round up for spot spraying but is there anything that treats a larger area without killing plants?

Could be common Bermuda. I see a lot of people make this mistake.

post a pic. dang near guarantee this is either common bermuda or nutsedge, especially if it is confined to the flowerbed and not taking over your entire yard already

There is some nutsedge but not alot. This is distinctly different from nutsedge.

There is definitely some in the yard as well. I have metal edging installed and thought that might keep it from invading the flower bed but it sounds like yall already knew that it would still find its way in there, which it has.

I cant imagine how you would confuse torpedo with nutsedge, or anything with nutsedge.

I have more than I would like, but it stays pretty buried underneath my zoysia, it will at times shoot into my beds. I have not been able to control it at all.

Unless it’s nutsedge, the answer for torpedo or bermuda in the flowerbeds is Fusillade II. Will take multiple applications to control torpedo.

I have the metal edging as well in my front pine straw beds. When I see it pop up, I pull back the pine straw and take a hand rake to carefully loosen the soil without breaking the root. I try to get it at it's deepest point. I do this multiple times a year to keep on top of it.

Man if you’d see some of the things people call “torpedo” in this place you’d understand lol. Idk how you mistake common Bermuda for Torpedo either, yet people think that all the time and I still think the guy in this thread has common Bermuda until pics prove otherwise.

Could use Quinclorac if it is torpedo grass. I would only spot spray it as I don't know what flowers it would take out.

I buried a 10" piece of aluminum around my bed on the side it was coming from and it appears to have still snuck back in under the sidewalk around the other side of the bed AND I must have missed a root under a plant because some is sprouting in other places as well. It's a menace to be sure.

Whoever gets the patent on actually killing it without killing the other plants is going to be really wealthy.

I've found Torpedo grass stolon's at least 18 inches deep when working in my backyard...metal edging won't stop it.

I spray over the top in a 3foot border around garden beds and it slows it down. Still have to spot pull 1-2x per week. Also spray round up directly on garden edges 1x per month.
