Overwintering Sarracenia in Toronto (Zone 5): Mulch, Don't Drain

For your S. oreophila, S. leucophylla, and S. minor in 10-inch pots in Toronto:

Recommended Method

• Keep pots in water trays. Do not remove water.
• Apply heavy mulch (bark, wood chips, pine needles, straw) over plants and pots—8+ inches deep.
• Spray sulfur fungicide generously before mulching.
• Do NOT use leaves as mulch—they harbor fungal spores.

Why This Works

Mulch prevents moisture loss from frozen soil and insulates against rapid temperature swings. The soil will freeze; that's fine. The mulch protects the crown and roots.
