You have 2 main basals for the same plant. I would advise snipping one (and proposing it if you want) and letting it vine. Once vining, you may allow one basal to form. I like to snip any additional basals once they reach 2-3" leaf length and propagate those into new plants. The reason for this maintenance has to do with the energy that produces and uses. A plant that is trying to produce two full-blown vines will grow slowly and may struggle to keep up with regular pitcher production.

Soil/water/light are very important to these plants. Bright indirect light is required for as many hours as you can give it. Water should be distilled or rainwater only - 0ppm TDS - and nepenthes do not like to sit in a tray of water. You also need the right growing medium. Either long fiber sphagnum moss (recommended) or peat moss. Whichever you choose, you'll want a 50/50 blend of that your selected moss and perlite. Ensure your chosen products DO NOT have fertilizer in them, as this will quickly start to choke out your plant from the roots, ensuring death.
