Flytraps need strong light , ideally 6+ hours of direct sun daily. Outdoors in full sun is best.
If you grow indoors, a south-facing window may work, but many indoor windows don’t supply enough light, in that case, use a grow light and keep it on for 12–16 hours/day.
Without enough light, traps become weak, pale, the plant will struggle.
Soil & Water
Use a nutrient-poor, acidic soil mix mimicking its natural boggy habitat, typically 50% sphagnum peat moss + 50% coarse sand or perlite. Avoid standard potting soil or mixes that include fertilizers.
Never fertilize your flytrap. In the wild they grow in nutrient-poor soils and get nutrients from insects. Fertilizer will likely kill or weaken them.
Watering: Keep the pot sitting in a tray or dish of distilled, rain, or reverse-osmosis water, about ½–1 inch deep. The soil should remain constantly moist, but not waterlogged.
Never use tap water (unless you’re absolutely sure it’s very soft, low in dissolved minerals). Most tap or well water will kill carnivorous plants over time.
During growing season the flytrap prefers warm temps (approx. 70–95°F / 21–35 °C). Indoors or outdoors if your summers are mild, this works great.
In its native coastal-plain region, the plant experiences colder winters, dormancy helps long-term health. If you grow outdoors and winters get chilly (near freezing), it’s best to allow a 3–4 month dormancy with cooler temps and reduced watering.
If you’re growing indoors year-round, dormancy isn’t strictly required, but reproducing cooler and shorter light conditions can improve vigor.
Venus flytraps are adapted to nutrient-poor bog soils and rely on insects/spiders (not soil nutrients). If your plant is indoors and doesn’t catch live prey, you can feed live insects (e.g. flies) occasionally. Avoid feeding meat, dead bugs, or fertilizer.
You don’t need a terrarium, in fact many experts advise against the small plastic “cup terrariums.” Let the plant breathe, especially if humidity is reasonable.
Repotting: Use a small pot (3–4 in / 8–10 cm), because flytraps have shallow roots. Use fresh peat+sand/perlite mix if you must repot, avoid regular potting mixes.
Don’t use tap water, most have too many dissolved minerals.
Don’t fertilize or use nutrient-rich soil.
Don’t under-light. Weak light = weak traps = plant decline.
Don’t let soil dry out. Flytraps hate dry roots; they evolved in boggy soils.
The flytrap is native to a narrow coastal region of North Carolina and South Carolina. It’s adapted to boggy, acidic, nutrient-poor soils, often maintained by natural fires and seasonal wet/dry cycles.
Because its wild habitat is shrinking (development, fire suppression, drainage), wild-collected flytraps are endangered. Always purchase from reliable growers who propagate plants responsibly, this protects native populations.
