Nepenthes thrive in warm, humid, and partly shady environments, daytime temperatures should be maintained around 18-27°C, with a minimum of 7°C at night, making them ideal for year-round indoor cultivation. They prefer being watered with rainwater, and many species benefit from sitting in a saucer filled with 2.5-5cm (1-2in) of water during the growing season. In winter, it's best to keep the compost damp rather than wet. Never add water into the pitchers as this can cause them to shrivel and die. Pot on in spring using a specialist carnivorous compost.
