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!
Centipede grass is most common in your part the of U.S. because of your climate. St. Augustine requires a more tropical climate. Your local County Extension office website is https://mecklenburg.ces.ncsu.edu/ contact them or take a sample to them for a true ID of the grass.
Zoysia hybrids have a higher price but better characteristics than both of the mentioned grasses. I have a similiar grass and was wondering about St Augustine as I am at the southern edge of the transition zone
