Talking to a guy about his lawn today, he has a beautiful lawn, mainly KBG, but he's upset that some other type of grass is creeping in. He had his lawn installed 5 years ago, and about 2 years ago this stuff showed up. It's appearing in patches all over his lawn. It appears to be some sort of zoysia-like grass, but I'm looking for a firm ID on it. Am I wrong that to get rid of it I'll have to spray glyphosate and reseed? The big question, then, is whether to spot spray, or just to completely kill the lawn and slit seed the whole thing. Is it too late (zone 5) to reseed a lawn now? I wouldn't mind getting a job this size now, I could use the extra work before leaf season gets here in earnest. Thanks in advance, guys!
