Not necessarily, I just wanted to make sure it was not a sedge which most people think is a grass, I know I did. So maybe you should just use roundup or a similar product. I had to do that just recently.
I forget what the product is called , but it is a similar to Round Up, just much cheaper. I sprayed it and waited, and waited, and waited, etc. you get the picture. Now several weeks later I am beginning to see results on the bamboo and some of the wild grasses and vines. Truthfully the poison ivy and some other weeds succumbed with in a week or so, but the bamboo and some of the wild grasses are just now really showing distress. Anyhow, I used it on a very calm morning, and very close to some of my plants, I mean very close. But I kept the spray directed away from the daylilies, and had no ill effects on them.
So if you don't find a more selective product specifically for your grass type, Roundup or some similar product can be used if you are careful around your plants.
My neighbor who owns the field behind me let me weed-eat a four foot wide path between his fence and my garden which is right next to the fence. That was back earlier in the spring. Then we sprayed a about 10 days later with Round up (his) and a lawn weed killer (mine). His worked so much better, but already it needs to be done again. But it is soooo much better than it would have been without spraying, at least right now I feel I have it under control.
