Sun

• In a greenhouse, a broad spectrum light that's not too close to the plant works best. You don't want to scorch the foliage or overheat the soil. In the garden, choose an area with partial sun: dappled sunlight is the best. If Nepenthes is not getting enough light, it will be spindly or it coloring may be washed out. Too much light will cause red spots and dead zones where the sun hits.
  
  

Moisture

• The soil beneath Nepenthes should never dry out. Occasionally, they need to be flooded to remove mineral salts that may come from well water or ground deposits. If there's not enough humidity in the air, the plants will not make pitchers. A greenhouse, terrarium or even a tent during the dry season will help them grow. Make sure they're well ventilated, to avoid mildew and rot. A garden mister may also help.
  
  

Soil

• A fibrous mossy soil mixture works well. Growers recommend vibrating the pot so that the soil settles around the roots, instead of pushing it down. Avoid soil with too much sodium and don't fertilize. The soil should drain well. Never allow water to stand in puddles, but keep the soil moist.
