I live an hour west of Scottychaos. I had my temperate CP's outside in minibogs last year, as I do this year. When the temps were forecasted to have overnight lows in the lower 30's I took toted them to the attic for the winter. I placed them at a SW window sill and watered them sparingly.... and waited winter out. I DID lose the 2 VFT's I had at the time, but attribute those losses to having been weak BEFORE I moved them. Every other species I had came back for me. Beginning in late February, one by one, first the D. filiformis, binata, rotundifolia, and intermedia. And the the Sarracenias and cobra lily. I used no fungicides. I just let the increasing photoperiod and waffling warmer temps determine when to break dormancy. I will do the same this year.
