Hi, bumping this up to see if anyone can help. Thank you!

What do you have there? Is it an invasion of one grassy weed into your normal grass lawn? Since all the grass I see if fine bladed, I'm thinking it might be creeping bentgrass. It spreads quickly and stays short/low.

Yes, this grass/weed is invading my normal grass lawn, which is dark green and grows straight. If it’s creeping bentgrass, how do I get rid of it? I have small patches of this in my front lawn but it’s taken over about 75% of my back yard. Thank you!
