I have a beautiful Sarracenia Scarlett belle growing a small bog garden I made out of a pond insert in my backyard in Kentucky. It has been pretty mild here so far and it looks great with ths some flytraps growing with it. I read that it has a semi-dormancy period. I have been planning to move the entire bog into an unheated garage for the Winter soon. How long should the Scarlett Belle be in there before i could bring it into the house? Thanks.
