Light requirements
Thrives on a sunny windowsill with several hours of direct sunlight.
How to care for venus fly trap
Full direct sunlight is absolutely essential — a south-facing windowsill at minimum. Stand in a tray of rainwater or distilled water at all times; never use tap water. Grow in pure sphagnum moss or a peat/perlite mix — never standard compost. Never fertilise. Needs a cold winter dormancy (2-10°C) for 3-4 months. Don't trigger traps for fun — each trap only closes ~5 times before dying.
Watering
Keep the compost consistently moist but not waterlogged. Check every few days.

- Seed (slow)
Toxicity
This plant is not known to be toxic to cats or dogs.
Common problems
