Venus Flytrap Care in Northern Ireland: Indoors vs. Outdoors

Question: I have a 'South West Giant' Venus flytrap in a 3:1 peat:sand mix, watered with rainwater. I live in Northern Ireland (mild, humid, cool summers: August highs 18°C/lows 11°C). It's on a south-facing windowsill. Should I move it outside for better light and humidity, or keep it inside for warmth? I worry cooler temps will trigger early dormancy. Also, can a flytrap overeat? Mine catches several flies daily.

Answer

Hi Mark,

Your summers are cool, but I'd recommend growing it outside. Photoperiod, not temperature, triggers dormancy. Outside, it gets better light and a natural seasonal cycle. Your climate resembles our Pacific coast in Oregon, where flytraps thrive. Add pea gravel atop the pot to warm the soil. Venus flytraps handle Irish winters fine.

As long as it catches its own insects, it's fine—they self-regulate. Overfeeding isn't an issue. For more details, visit our care sheets: www.cobraplant.com/caresheets.

Good Growing!
