Does anybody use Christmas lights for the freeze?
I read I the paper that you can use older (not LED) Christmas lights to wrap around plants As a faint heat source in a freeze. The article might have said to also throw a sheet over the plant, but I can't remember.
I'm convinced that we didn't get any freezes last winter because I left my Christmas lights box in the garage, just in case I needed them, while the rest of the Christmas stuff went back in the attic.
Has anybody tried this? Any advice on how best to use them for this purpose?
