First off, greetings to everyone - I'm brand spankin' new here. Secondly, I've moved into this house a year ago just east of Charlotte, NC and trying to identify the grass in my back yard. I've narrowed it down to what I think is either Centipede or St. Augustine, and I feel pretty sure it's actually St. Augustine because of the opposite blade patterns. However, folks around here say St. Augustine doesn't grow here and therefore must be Centipede. It's a nice, established lawn, so whatever it has grown well for at least several years. Please look at the pictures and let me know what you guys think, and thanks in advance!
