Betty, I would say they should be fine. We had nights in the teens last winter, Fred and James' seedlings did just fine. Fred's were in the ground and James' newer ones were in pots. I had a couple of geraniums on my porch and where they were sitting one was protected from the wind and the other was not. The protected one lived and kept growing, the other one froze. So if the porch is covered I would say they will be just fine. How new are your babies and what are they in?
