When to Cover Venus Flytraps and Pitcher Plants for Winter in Mountainous Virginia

A bog garden owner near Roanoke, VA (mountainous) asked when to cover plants: after first frost for flytraps, after several for pitchers. Forecast: low of 24°F next week.

Rule of Thumb

Cover when daytime temperatures will not rise above freezing. In similar Oregon conditions, plants stay uncovered until a prolonged deep freeze is predicted.

Current Forecast

With daytime highs above freezing, leave them uncovered. Mulch (black plastic, fabric) only when days stay at or below 32°F.
