Calgary Zone 3 Venus Flytrap Winter: Mulch Box in Garage Protocol

A Calgary grower plans VFT dormancy in mulch box in unheated garage. Asks about leaf trimming, margarine container water reservoir, black bag over mulch.

Expert Guidance

Cut all leaves — beneficial in extreme cold
Margarine container water = OK, minimal water
Black bag in garage = overkill (wind protection not needed indoors)
Mulch + occasional watering sufficient
Fungicide essential — saturate crown even if frozen
Frozen soil? Spray anyway — penetrates during thaws
