I had a pitcher plant too last year. When it started to die back I stuck it in a Styrofoam cooler and put it in the garage (I'm in MN and even in the cooler it probably got too cold). A little over a month ago I took it out of 'hibernation' and started watering it again. Nothing... It's deader then dirt, I've been watering a bare pot for a month now. I've been to several carnivorous plant sites and have been reading up but just can't seem to get the hang of it.
