The property is from 1973 but I bought the house in 2008. The previous owner planted the grass. He is the one who told me it was zoysia. The grass is growing well in most of the yard but because of a new puppy and some over grown sweet gum trees, about 30% of the yard does not look good. I cut down the trees shading the lawn and trained the puppy. It’s time to get the grass back into shape which is why I am trying to figure out the species so I can treat it properly. Thank you everyone for you help identifying the grass for me!

I recently saw there are 38 cultivars of Zoysia now and, counting. Just guessing, you may have zenith. How old is the property and are there large areas of the grass or just scattered patches?

Addendum to my last post: http://www.walterreeves.com/gardening-q-and-a/carpetgrass-in-centipede-lawn/

Could it be Carpetgrass? If so, you will know when it produces seed heads. It’s mixed in with my centipede and was misidentified as centipede by an extension agent to whom I showed the leaves and stolons. I don’t like it. It’s hard to eradicate without harming the centipede. http://www.clemson.edu/extension/hgic/plants/landscape/lawns/hgic1213.html

Is that brown spike with lateral appendages your Zoysia grass? If so it doesn’t look like Zoysia. http://www.lsuagcenter.com/NR/rdonlyres/6CBE2817-AD7C-4A92-8278-FAA4DCC8A5FE/35882/Img1526.JPG
