Overwintering Container Carnivorous Plants: Mulch Depth, Burlap, and Fungicide

Mulching and Protecting Pots in Zone 5

Apply 6–10 inches of mulch from soil line up the pot sides. Build a wooden frame to hold mulch, removing it in spring. Before mulching, trim leaves taller than 4 inches and spray plants and soil with fungicide (Neem oil is fine; use generously). Fungus isn't an issue once temperatures stay below freezing.

Burlap Placement

Place burlap over mulch to secure it against wind. If using underneath, ensure burlap is new (used burlap may harbor spores) and fill all gaps to minimize air pockets.

Goal: reduce rapid temperature swings and prevent dehydration from freezing wind.

Good growing!
