Protecting Sarracenia During Extreme Winter Cold: A UK Grower's Guide

When to Cover Plants

• Cover if temperatures drop below -4°C (25°F) for more than a night or two, especially with wind.
• Always cover if temps stay below freezing (arctic high-pressure systems).
• Never cover during wet, cold weather—plants handle frost and snow naturally.

Observations from a Severe Freeze (-14°C / 7°F)

Losses: D. filiformis "Florida Giant", D. filiformis ssp. tracyi, exposed flytraps, S. leucophylla "Titan", some S. minor.
Survivors: S. psittacina (contrary to reputation), S. leucophylla "Tarnok", large D. binata dichotoma.

Post-Cold Care

• Uncover when temperatures stay above freezing for a sustained period.
• Spray with fungicide if plants were covered long-term.

Good Growing!
