I think perhaps you're right @gjones. I have no idea which kinds I have, but only what I think is aloe vera seems to be in trouble. The small spiky one is only there because I think it looks nice. I have many babies of that one and they all seem to be doing fine in the orangery.
We'll see if it is too much of a shock moving them from cold and damp 4 degrees to 22 very dry ones. Hopefully they will be ok @columbiariver. It was a small plant from IKEA some years ago, now it is larger and divided several times. Don't think I've overwintered it in the orangery before.
All you succulent lovers out there: When my aloe turns mushy brown and gel-like, have I given it too much water, or is it something else? It has hardly gotten any all winter, but perhaps my orangery has been too cold and damp for it?
I think I will try that @gjones. There is no heating at all in that room, and temps this time of year typically are between 4 and 10 degrees. If I'm not careful, mold can be an issue on over-wintering pots (but not on my succulents since they are kept dry).
