Thanks for the reply. I think I will mow a small section of it and see what happens. The turnips are 8" -12" high and the turnip itself is about the size of a golfball right now. And yes, I do plan to leave them over winter.
Last year I left my corn stand all winter, and the stalks gave me some trouble this spring. With the cedar swamp so close, I think I' m going to have it picked this year.
