Venus flytraps (Dionaea muscipla) require distilled or rain water, and should be kept in constantly moist soil. They require intense sunlight and should be kept outdoors during the growing season or under strong grow lights indoors. Plants will enter a dormant state if left outdoors late into the fall, at which point they can be brought inside and placed in a refrigerator to rest until spring. Dormancy is necessary for long-term health and without it their lifespan will be shortened to a few years.
Feeding can be done sparingly and is not necessary. Live insects must be used as the traps will reopen if no movement is detected. Flowers should normally be cut as they emerge.
