unwanted grass in my yard
I have had for several years a reoccurrence if a type of grass that from a distance looks much the grass on a golf course green. It goes dormant early in the fall and spreads a bit more each year. I have tried killing it using roundup, but it manages to take hold the next year and starts advancing all over again.
I have included a photo of some of the grass to help identify.
Thanks in advance for any help or suggestions.
