Provide the Nepenthes with an acidic growing medium and humidity. Use a large terrarium or aquarium with at least 4 inches of peat moss.
Situate the terrarium in bright, filtered light, such as 2 to 3 feet away from a south-facing window with a sheer curtain. Don't put the terrarium right next to the window to avoid excessive temperature fluctuations and the risk of cooking the plant in hot sunlight through glass.
Keep the peat moist, but don't saturate it. Mist the Nepenthes regularly, such as ever one to two days, to provide more humidity, especially in hot weather. It's normal for the pitchers to collect water. If condensation collects on the terrarium glass, open the lid partway for an hour or longer to reduce the moisture.
Feed the Nepenthes bicalcarata traps a 1/2 inch of blood worm every two to four weeks once the traps mature. For example, start feeding them when the pitcher is 1 1/2 to 2 inches long.
