Tiff, it went down to 43 deg. last night and it is expected to get colder beginning today and a deep freeze is expected within the next 10 days to 2 weeks. I am not even opening the doors today to check so the sun can warm it up today and I can take advantage of the solar heat remaining in there tonight to help the heaters.
It went down to 36deg a few weeks ago and it killed 4 plain green and 1 reverse and 3 variegated. The curly were fine. They were all in a line on the lower shelf close to the wall. I have since moved them closer to the front of the shelf. I would have done that sooner but I did not think they were going to mind the cold if it was just one night. I learned the hard way. I mean they froze, they were all black. Poor babies I felt so bad I could have cried. I can feel when they are sad. Am I crazy or what?
