Overwintering North American Carnivorous Plants in Zone 5 Without a Garage: Mulch Method

Winter protection isn't about preventing soil freeze—it's about preventing moisture loss from frozen leaves and insulating against rapid temperature swings.

Effective Mulch Method

Use bark, wood chips, pine needles, or straw (NOT leaves—fungal risk).
Apply 8+ inches over plants and pots after several frosts and consistent 40s°F days.
Spray sulfur fungicide heavily before mulching.

Alternative: Refrigerator Dormancy

Detailed in our e-book Secrets to Growing Beautiful Carnivorous Plants. Requires gradual cooling first.
