Venus Flytraps – carnivorous plants – How to Grow and Care

Venus flytraps ( Dionaea muscipula ) are one of the most popular and intriguing carnivorous plants in the world. They have specialized leaves that can snap shut and trap insects inside, where they are digested by enzymes. Venus flytraps are native to a small region of North and South Carolina, where they grow in poor, acidic, and moist soils. They are also grown as houseplants by many enthusiasts, but they require some special conditions and attention to thrive.

In this article, we will show you how to grow and care for a Venus flytrap, covering the following aspects:

  • Light
  • Soil
  • Water
  • Feeding
  • Temperature and humidity
  • Dormancy
  • Propagation
  • Pests and diseases

By following these tips, you can enjoy the beauty and fascination of these amazing plants for years to come.


Venus flytraps need bright, direct sunlight to grow well and produce healthy traps. They can tolerate some shade, but too much shade will make them weak and leggy. Ideally, they should receive at least 6 hours of full sun per day, preferably more. If you are growing them indoors, place them near a south-facing window, or use artificial lights such as fluorescent or LED bulbs. You can also grow them outdoors during the warmer months, but make sure to acclimate them gradually to avoid sunburn.


Venus flytraps are adapted to grow in nutrient-poor, acidic, and well-drained soils. They do not tolerate regular potting soil, which can burn their roots and kill them. The best soil mix for Venus flytraps is a blend of one-third perlite (or sand) and two-thirds sphagnum peat moss. This provides good aeration, moisture retention, and acidity. You can also add a few pieces of orchid bark or charcoal to improve drainage and prevent fungal growth. Avoid using any fertilizers or compost, as they can harm the plants.


Watering is one of the most important aspects of Venus flytrap care. These plants need constant moisture, but not soggy conditions. They also need pure water, as they are sensitive to minerals, salts, and chlorine. The best water sources for Venus flytraps are rainwater, distilled water, or reverse osmosis water. Do not use tap water, unless you filter it or let it sit for a few days to evaporate the chlorine.

The best way to water Venus flytraps is to use the tray method. This involves placing the pot in a tray or saucer filled with water, and letting the soil absorb the water from the bottom. This mimics the natural habitat of the plants, where they grow in boggy areas. The water level should be about half an inch high, and never higher than the pot rim. Check the tray regularly and refill it as needed. Do not water the plants from above, as this can wash away the soil and trigger the traps unnecessarily.

Venus flytraps get most of their nutrients from the insects they catch and digest. They do not need to be fed regularly, as they can survive on photosynthesis alone. However, feeding them occasionally can help them grow faster and produce larger traps. The best food for Venus flytraps are live insects that can fit entirely inside the traps, such as flies, mosquitoes, gnats, spiders, or ants. You can also use freeze-dried insects, such as bloodworms or crickets, but you need to rehydrate them first.

To feed a Venus flytrap, gently place the insect on the center of an open trap, and wait for it to close. The trap will close only if the insect touches the hair-like sensors on the inner surface of the lobes. Once the trap is closed, it will seal tightly and start producing digestive enzymes. The digestion process can take from a few days to a few weeks, depending on the size of the prey. When the trap reopens, you can remove the leftover exoskeleton with tweezers.

You should only feed one trap at a time, and allow 2 to 6 weeks between feedings. Do not overfeed the plants, as this can stress them and cause the traps to die. Do not feed them during dormancy, as they are not active and will not digest the food. Do not experiment with human food, such as meat, cheese, or candy, as they can rot and damage the plants. Do not feed them with bugs that are too large, too hard, or too hairy, as they can get stuck or injure the traps.

Temperature and humidity

Venus flytraps prefer warm and humid conditions, but they can tolerate a wide range of temperatures. They can grow well in temperatures between 50°F and 95°F, but they prefer 70°F to 85°F. They can survive brief frosts, but they should be protected from extreme cold or heat. If you are growing them indoors, you can use a thermometer and a humidifier to monitor and adjust the temperature and humidity levels. If you are growing them outdoors, you can move them to a sheltered spot during the hottest or coldest days.

Venus flytraps are not evergreen plants. They have a natural dormancy period, where they stop growing and most of their leaves die back. This usually happens in late fall or early winter, when the days get shorter and the temperatures drop. The dormancy period is essential for the health and longevity of the plants, as it allows them to rest and conserve energy. Without dormancy, the plants will weaken and eventually die.

To induce dormancy, you need to reduce the light, water, and temperature gradually. You can either leave the plants outdoors, if the climate is mild, or move them indoors, to a cool and dark place, such as a basement, garage, or refrigerator. The ideal temperature for dormancy is between 35°F and 50°F. The dormancy period can last from 3 to 5 months, depending on the variety and the conditions. During dormancy, you should water the plants sparingly, and do not feed them at all. You should also remove any dead or diseased leaves, and any flower stalks that may appear.

To end dormancy, you need to reverse the process and increase the light, water, and temperature gradually. You can either move the plants outdoors, when the weather is warm enough, or place them near a sunny window, or under artificial lights. You should resume the normal watering and feeding schedule, and wait for the new growth to emerge. The plants will produce new leaves and traps, and resume their normal activity.

Venus flytraps can be propagated by seeds, rhizomes, or leaf cuttings. Propagating by seeds is the most challenging and time-consuming method, as the seeds are very small and slow to germinate. They also need to be stratified, or exposed to cold and moist conditions, for 6 to 12 weeks before sowing. The seeds can be sown on the surface of moist peat moss, and kept in a warm and bright place. The germination can take from 4 to 12 weeks, and the seedlings can take several years to reach maturity.

Propagating by rhizomes or leaf cuttings is the easiest and fastest method, as it produces clones of the parent plant. Rhizomes are underground stems that can produce new shoots and roots. Leaf cuttings are detached leaves that can form new plants at the base. Both methods can be done in spring or summer, when the plants are actively growing. To propagate by rhizomes, you need to carefully dig up the plant and divide the rhizome into sections, each with at least one shoot and one root.

To propagate by leaf cuttings, you need to cut off a healthy leaf near the base, and insert it into moist peat moss. Both rhizomes and leaf cuttings should be placed in a warm and humid environment, such as a plastic bag or a terrarium, and kept in bright indirect light. The roots and shoots should develop in a few weeks, and the new plants can be transplanted into individual pots.

Pests and diseases

Venus flytraps are generally healthy plants, but they can be affected by some pests and diseases. The most common pests are aphids, spider mites, mealybugs, and fungus gnats, which can suck the sap and damage the leaves and traps. The best way to prevent and control these pests is to inspect the plants regularly, and remove any infested parts with tweezers or a cotton swab dipped in alcohol. You can also use insecticidal soap or neem oil, but avoid spraying the traps, as they can be sensitive to chemicals.

The most common diseases are fungal and bacterial infections, which can cause rotting, wilting, and discoloration. The best way to prevent and control these diseases is to avoid overwatering and overcrowding, and provide good air circulation and drainage. You can also use fungicides or bactericides, but follow the instructions carefully, and test them on a small area first.

Venus flytraps are fascinating and rewarding plants to grow, but they require some special care and attention. By providing them with the right light, soil, water, feeding, temperature, humidity, dormancy, propagation, and pest and disease control
