I've been growing VFTs a few years and I've never been quite sure about freezing temperatures when it comes to VFTs/Sarracenia. Normally whenever it drops down to freezing temps I just move my plants into the garage to protect them, since I'd rather be safe than sorry.
However, recently when discussing dormancy online, I've had someone insist that I'm doing it wrong, and that VFTs need to encounter frost in order to produce "antifreeze" cells that will protect them from freezing temps, and that I can just leave them outside to freeze into a solid block of ice and they'll still be fine. They linked me some Sarracenia Northwest videos where the same is discussed.
Is any of this true at all? Because even in the same video that got linked to me, I saw people in the comments section saying they left their plants outside during frosts and they all died. I've also definitely seen people keep their plants outside during freezes lose them, and I'm pretty sure having the media freeze and thaw repeatedly is bad for the plants anyways.
I know that bigger pots/bogs tend to do better with freezing temps, but they insisted that their 4" pot VFT survives freezing temps with no problem as well.
