Overwintering geraniums

Well it's still too cold outside. I have some on my bedroom windowsills. So you could have them
Down by a window. Move out to a greenhouse when the temps warm up a little? I do have some in the greenhouse - those that I wasn't worried about losing. I missed one and forgot to fleece - that's dead. There's about 12 others that are under my bench covered in several layers of fleece. They are ok so far.

House ones are looking much better.
