Caring for carnivorous plants properly – can you feed them?. You shouldn't play with the leaves of the Venus flytrap (Dionaea muscipula) too much - otherwise they will die.
Pitcher plants (Nepenthes spec.) prefer fish food. Fertilizing: No additional fertilizer necessary, if possible do not feed. If using tap water, repot once a year, advises Carnivory.eu. Since carnivore plants also like high humidity of up to 80 percent, they can be kept well in a terrarium or in a bottle garden.
