Venus flytraps (Dionaea muscipula) are sun-loving bog plants native to a small region of the southeastern United States. They do best when their basic needs are met consistently: strong light, mineral-free water, nutrient-poor media, and a cool winter rest.

Light

Give outdoor plants several hours of direct sun and acclimate them gradually when moving them into stronger light. Indoors, use a strong horticultural grow light on a consistent day length. Weak light commonly leads to stretched growth and small traps.

Water

Use rainwater, distilled water, or reverse-osmosis water with very low dissolved minerals. During active growth, keep the growing medium consistently wet; standing a pot in a shallow tray of water is a common method. Do not use softened, mineral-rich tap water.

Growing medium and pots

Use an unfertilized, mineral-poor mix such as sphagnum peat and perlite or long-fiber sphagnum. Avoid ordinary potting soil, compost, and fertilizer. Plastic or glazed pots are generally safer than unglazed clay, which can leach minerals.

A note from our growing experience: We have found that growing Venus flytraps in 100% long-fibered sphagnum moss (LFSM) can be very beneficial. It is a more expensive growing medium, but in our experience, the benefits can make the additional cost worthwhile. This is our preferred approach, rather than a requirement for every grower.

Dormancy

Venus flytraps need a cool winter dormancy, usually for several months. Growth naturally slows and some leaves may blacken. Keep the plant cool and damp, not warm and actively growing year-round. Protect it from hard freezes and prolonged waterlogging in conditions it cannot tolerate.

Feeding and common problems

A healthy outdoor plant catches its own prey. Never trigger traps repeatedly for entertainment, and do not put meat or fertilizer into the traps. Poor light, mineral buildup, and skipping dormancy are common causes of decline. Remove dead leaves when they are fully brown, using clean tools.
