Overwintering Bare-Root Sarracenia and Flytraps in Germany (Zone 7)

A grower in Frankfurt, Germany (Zone 7, lows 0–10°F) received bare-root S. minor, S. psittacina, and three flytrap clones in late October. Plants were small (flytraps 2 inches, S. minor pitchers 12 inches). He asked whether to induce dormancy or skip it to avoid transplant shock, and how to overwinter them.

Jeff Dallas recommends overwintering in a cool indoor window. Since the plants' prior conditions (greenhouse vs. outdoor) are unknown, a refrigerator dormancy is too risky. Keep soil moist but not waterlogged—no more than 1 cm water in trays. Top-water to maintain soil freshness and reduce mold spores. When spring arrives and frost danger passes, move plants outdoors permanently; all are fully hardy to Zone 7.

In a follow-up, Dallas specifies the window should reach nighttime temperatures in the 50s°F or lower with natural daylight hours. This combination of cool temperatures and shortening photoperiod induces adequate dormancy, though shorter than outdoor dormancy.

Dallas recommends the Sarracenia Northwest Volume 1 DVD for detailed winter care and the website's basic care guide.
