Dead grass question

[Arrgh]

4. Depends the grass, and the climate.

I have centipede grass, a warm season grass, in SC. It goes dormant at the first frost and stays brown until spring. I give it a nice trim (and mulch whatever leaves are left) one last time and let it sit until then. I like it that way.

I could overseed it with annual ryegrass and have some green over the winter, but then I'd have to cut it.

You'll need to know more about what's in your lawn before you can get an answer.
