Venus flytrap thrives in poor, acidic soil that stays damp but still has good drainage. Avoid planting it in regular potting soil: A blend of one-third sand and two-thirds sphagnum peat moss provides the best drainage and moisture retention. Don’t add lime to the soil and never add fertilizer.
Venus flytraps do best in bright but indirect light. It’s especially important to avoid placing them in direct sunlight in summer, which may get too hot and cause the leaves to turn crispy.
When grown inside under artificial lights, keep flytraps 4 to 7 inches away from fluorescent lights. If your plant’s traps don’t show a pink interior or if the leaves look long and spindly, provide more light.
For best Venus flytrap care, keep the environment humid and the soil moist but don’t let the plants stand constantly in water. You’ll be most successful if you provide a humid environment by putting the plant inside of a terrarium with some air flow via a gap in the lid.
Never give your plants what comes out of your tap; it’s usually too alkaline or might have too many minerals. Instead, rely on rain or use distilled water. Good air circulation is also important in growing Venus flytrap plants, so turn a fan on in the room where you keep them.
