How cold? There were a few nights we probably should have covered some plants.
We have a bunch of plants in an unheated south-facing sunroom. In the summer it's great! Usually not too much of an issue in the winter for most of the plants we leave in there. It heats up real nice if the sun is out, but I think the issue we had last year was the sustained cold days & nights. There were a couple nights it got around 0 - 10° and we lost a bunch of plants.
This is Buffalo....
I wonder if the spots on my cactus might be the results of 'frostbite'? We did end up repotting it in a clay pot with new soil, at least. I think in spring I'll probably try to take a cutting or two.. see what happens.
