Hi Elisa,
Sorry I couldn't get to you before this but my computer was too ill to work for quite a while. I've had a similar situation so here's what I would recommend.
I don't know where you have been keeping them, but they all really need the cold conditions outdoors. If you can find mulch or top soil that isn't frozen, go ahead and put the
plants on top of the soil with enough room between them so you can fill in with the mulch or soil. Make sure they are watered well before you do this. This is called healing in.
If it's possible that the soil isn't frozen yet, you could dig holes and just put the pots into the soil up to their rims for the winter. Topdress with mulch or soil.
Hope this helps,
Newt
