Hey all, thanks for the feedback.
I'm very hesitant to buy new plants in the winter which is why I rarely do. This was a sale given by a particularly excellent seller in California and I really didn't want to let it pass.
I'm also very hesitant to put them outside in the winters here. I seem to get a lot of different opinions from people; and some of those from this group have me second-guessing whether I want to try this. I live in Nebraska, and it gets FAREEZING here....frozen solid ground, nights falling below 0 degrees F weeks in a row. It scares me. Perhaps I'll stick to my fridge method after hearing some of the feedback here.
Now that I know where you live:
You should not attempt to overwinter VFTs or Sarrs outside..ever.
your climate is WAY too cold..don't even consider it.
