Cameron in Minnesota has dormant Sarracenia 'Dana's Delight' in terrarium with brown pitchers, springy dark roots. Christopher: "That is the problem with terrariums, they create stagnant, moldy conditions that can infect and kill off dormant plants. Also, warmth in winter is not the answer... They would need to remain just above freezing most of the time, around 40-50°F."
Brown roots = dead (should be creamy white, stiff). Terrariums cause mold, restrict airflow, create bacterial breeding grounds. Adapt plants to lower humidity slowly (plastic bag with increasing holes over 2-3 weeks). Grow open-pot with good watering.
