Answer
Hello Portia,

I am assuming that what you have is a Nepenthes (Asian Pitcher Plant) from your description as there are five genera of very different pitcher plants from around the world.

There are several factors that affect Nepenthes pitchering.

Light is one of the main aspects that people often underestimate. Nepenthes need very bright, just short of, full sunlight. They live under trees in their natural habitat and usually receive several hours of morning and evening sunlight with some partial shading from tree limbs during the noontime. Insufficient light can cause Nepenthes to fail to pitcher.

Nepenthes react very drastically to changes in humidity. If humidity drops quickly and drastically one or more times a day, it can harm the plant and force it to fail to pitcher as the pitchers dry out before they form. Plants tend to require stable humdity over the course of a day to maintain their water retention.

Nepenthes do prefer only moist soil, so a saucer under the pot is not required.

Spraying is not required, just a stable environment that maintains humdity and temperature over time. You may also need to find out what exact species your Nepenthes is as some are more demanding than others. If your species is an easy to grow one, all it needs is a well lit, stable environment and time to adjust.
