Carnivorous plants require little maintenance. We must give them what they need: light and water. Most carnivorous plants are very light-loving and what could be better than sunlight. The type of soil that is favorable is mainly composed of sphagnum peat moss; this soil should remain moist for most carnivorous plants. Since these plants, in the middle of nature, live in an environment very poor in minerals, it is important to water them with rain water or distilled water.
As bizarre as it may sound, carnivorous plants are subject to attack by insects. Some plants are more sensitive than others. You will have to monitor them and take the necessary measures to protect them against these attacks which can weaken or even kill your plant.
