Most winters there are only a few hard freezes, and usually not enough to kill these citrus trees. However, a few winters back, it did not reach above freezing temps for 48 hours. I lost my two beautiful navel orange trees that were producing around 30 oranges each.
I replanted, then set about looking for a way to keep them warm on the coldest nights. The “magic”? Old, hot, outdoor Christmas lights!
My trees have been happy with their lights, and I think they may share a little Christmas cheer as well. Even through February.
