If you're afraid to own a Venus flytrap because of its exotic nature, fear no more. They're actually easier to care for than average houseplants and don't need bugs to survive. To keep them healthy, just provide your plants with a good start and a few basic necessities and watch them flourish all on their own.
Create the right soil mix. Avoid potting mix or houseplant soil. Chose a nutrient poor mix of sphagnum moss, perlite and peat because Venus flytraps do not get their nutrients from the soil. Using the right soil prevents build up of elements that damage your plant's root structure.
Use the best possible water. Use only rainwater or purified water. Avoid avoid tap water because it contains trace amounts of magnesium, fluoride, salts and other chemicals that your plant cannot use and that build up to toxic levels over time.
Find the sunniest place in your home. You must be able to provide four solid hours per day of intense, bright sunlight that directly shines on your Venus fly trap. Place your plant outside for four hours if you do not have these conditions in your home. Overall, provide 12 hours of total sun exposure with four being direct exposure.
Decide whether or not to feed the plant insects; this practice is optional. Venus flytraps do not need to eat insects to survive. If you choose to feed insects to your plant, either allow the plant to hunt naturally or provide one insect per week. Avoid insects that have been exposed to chemical pesticides or traps.
Avoid fertilizers and any foods besides insects. Dropping in anything other than insects will kill the plant. A Venus flytrap has very specifically evolved digestive mechanisms which are not designed to break down complex fibers or proteins. If you feed the plant anything which it cannot digest, the lobes will turn black and rot off.
Provide basic housekeeping for the plant while it is dormant. Each winter your Venus flytrap will die back. During this time almost all of the plant will wither away and die; however, it will come back at full strength once warmer weather returns. Remove dead foliage to prevent rotting and fungal growth.
