Overwintering Sarracenia and Darlingtonia Below 20°F: Straw + Plastic

Derick faces well-below-20°F winters. Asked if straw mulch + wind shelter suffices, and how the nursery winterizes.

Straw + Plastic During Extreme Cold

Thick straw layer + plastic cover during coldest snaps works. Remove plastic when temps rise significantly above freezing (leave straw). Nursery (PNW) pins black plastic over pools during Arctic air (teens°F). Plants on ground, not tables. Coldest: 7°F for couple days—all Sarracenia, Darlingtonia, NA sundews, VFTs, Euro butterworts survive this way. Plastic off when rain returns.
