I have many Chlorophytum comosum in my flower bed. Unfortunately, I have a lot of Bermuda grass growing all in the plants. Spraying glyphosate around everything doesn't kill the grass growing up through the plants. I'm trying to spray a herbicide that will kill the grass, but not the Chlorophytum comosum. Is that plant an actual grass? I was trying to see if a grass specific herbicide would harm the plants.

Bermuda grass is exceptionally hard to kill. I don't know of anything that will even discourage it that won't kill everything else first. Pull it out by hand and keep after it. Good luck!

Dig it all, then pull the grass out of the C c and replant.
