You don’t need to protect turnips in your area. We’ve had them planted outside in the lower part of our property since last September. They did spectacularly until we had the night it got down to 10F on my back porch. It was probably 7 or 8F or cooler in the turnip spot. It got down to 8F on my back porch several weeks later and may have been down to 5F in the garden.
They’re still mostly green but their tips look kind of singed. Definitely still alive though. Not terribly happy about it though!
Here’s a list of veg and hardy temps:

Thanks for that link, put it in a Word document and printed it. I need to have/know that information.
