Determining Dormancy Timing for Temperate Carnivorous Plants in Variable Weather

Plants use both temperature and photoperiod to trigger dormancy. By late fall, short days have already induced dormancy even if temperatures fluctuate.

Recommendation

• Leave plants uncovered a bit longer to build cold tolerance.
• Mulch and cover when an Arctic front is forecast (sustained freezing).
• Don't wait for "perfect" conditions—act before extreme cold hits.

Good Growing!
