I had about a dozen first-year Sarra seedlings that I just put in a greenhouse, but I don't think they survived being in the garage for a month. I think they were frozen too long. Oh well, at least it was only 12. I will be putting my 2-year-old seedlings in the greenhouse either tonight or tomorrow. They've been in the garage since thanksgiving-ish, and pretty much frozen for that time. Had kind of a mini-thaw the week prior to christmas, where it was above freezing in the garage, but not enough to completely thaw them out. They all appear to still be alive, so hopefully they start sending new growth up in a couple of weeks. My mature plants are in lg. mini-bogs and impossible to transport to the greenhouse, so they'll stay in the garage for 3 more months. It's not an ideal situation for them, but I only had 1 year where I suffered losses.
