In The book "Savage Garden" by Peter D'Amato, he writes that some VFT owners trim off the leaves and store the rhizome in the refridgerator for winter dormancy. My VFT is small enough to put the entire plant, pot and all, in the refridgerator. But next year this may not be practical and I am looking for another solution. I live in an apartment in NY and do not have outside access. Is the process discussed in "Savage Garden" a good one?
