I live in the Nashville, TN area, and I've noticed a particular type of grassy weed starting to pop up in my lawn, now that it's March. I'd like to identify it so that I can learn how to prevent it from spreading further.
It's a lighter green color than the rest of my lawn, and its leaf blades are flat and approximately double the width of my other grass. The stem is round near the bottom, with multiple leaves branching from the sides as it goes up. It has what looks like a small purple taproot with smaller roots coming out of it.
I apologize for the quality of these photos (especially the third one!), as I couldn't gauge how clear they were in the sunlight on my phone. If they don't help, I'll try to get better photos to replace these.

We had a lot of dallisgrass last year, so I'm curious if this is young dallisgrass, which I understand is a bit easier to treat than after its been around for a few weeks.
