I've learned that VFTs need to go through a dormant period. It was going to be put in the crawlspace or garage, but will it die from lack of light, if I do this? .Also, do I need to give it moisture during dormancy?
Yes I THINK they do still need light if your leaving it in the pot, i have heard of people storing them in the fridge though so maybe not. If in the pot don't let it dry out but they do need less water, they can rot easy in winter. Sorry i can't be much help. Mine don't really die down here, not cool enough, does yours die right away? I'd unpot it and store it if it does.
Thanks for the info tommyr2006. I plan to put mine in the unheated crawlspace under my house, when the nights get down to the mid 20s. Then bring it outside when the temps are 35. I'll have that sulfer based fungicide on hand, in case it's needed.
