So the past two years since I've moved into my new construction home I've been trying to get my Tifway 419 to grow into the ditch. I've been killing off weeds and Coastal Bermuda ( at least that's that I think it is), its grow like a weed and the "runners" are twice the size of the tifway. I thought things were looking pretty good as far as growth of the tifway into the ditch till I notice this grass in the picture. It's the grass that's longer than the rest in the picture towards the top.
