Canadian Venus Flytrap & Sarracenia Winter: Fridge Method vs Outdoor Mulch

A Canadian grower asks about fridge dormancy for VFTs and S. purpurea since outdoors is too cold.

Fridge Method (If Plants Already Dormant)

1. Unpot, rinse soil
2. Sulfur fungicide spray
3. Wrap roots in damp long-fiber sphagnum
4. Loose plastic bag in refrigerator
5. Check monthly for mold
6. Repot after 3 months, grow in south window until outdoor safe

Critical Error to Avoid

If plants were brought indoors at first frost, they're NOT dormant. Fridge will shock them. Must overwinter in bright south window instead.

Outdoor Success in Canada

• Some growers succeed with THICK mulch
• S. purpurea ssp. purpurea is native to Canada
