Sarracenia and Venus Flytrap Dormancy in Tropical Highlands (Cairns, Australia)

Fridge Dormancy Not Needed for Sarracenia

At 757m elevation near Cairns, winter lows reach 5°C (41°F), highs 22°C (72°F). Sarracenia will undergo a short natural dormancy with reduced daylight—no refrigeration needed. Venus flytraps need more dormancy; shade cloth may help, but fridge method works if fungicide (sulfur) is used. Alternatively, grow under artificial light on an 8-hour day to mimic North American winter.
