How to Grow Nepenthes

No terrariums. No myths. No nonsense.
Practical advice based on decades of growing and propagating carnivorous plants.

About This Guide

This guide focuses on commonly available Nepenthes species and hybrids grown as houseplants. Some rare and specialty Nepenthes have narrower environmental requirements and may perform best with more carefully controlled temperatures, humidity, lighting, and airflow. These narrower requirements are not typical of the commonly available Nepenthes covered in this guide.

Nepenthes Care at a Glance

Growing Requirement	Our Recommendation
Light	Several hours of unobstructed, direct sunlight with bright filtered light during the rest of the day. Avoid full shade.
Artificial Light	Use LED shop lights producing approximately 2,500 lumens or more, starting about 12 inches above the plant. Use a 14-hour daylight cycle.
Temperature	Days in the 70s°F (22–26°C) with nights in the 60s°F (16–20°C). Avoid frost and prolonged temperatures in the 40s°F.
Humidity	Most commonly grown Nepenthes can acclimate to normal household humidity. Higher humidity may produce somewhat larger pitchers, but it is not a driving force for pitcher production in the way that sunlight and temperature are.
Water	Water thoroughly and allow excess water to drain. Nepenthes can tolerate water up to approximately 200 ppm. Avoid standing water.
Soil	Use 1 part dried sphagnum moss to 1 part perlite. Do not use conventional potting soil or compost.

Grower's Key Point

The most important factor for pitcher production is adequate light. If your Nepenthes is growing leaves but not producing pitchers, insufficient light is one of the first things to investigate.

Where Do Nepenthes Grow Naturally?

The genus Nepenthes occupies a vast natural range, spanning from Madagascar and the Seychelles, India and Indochina, throughout the innumerable islands of Southeast Asia, and into the northeastern cape of Australia. Such a gigantic distribution has resulted in an extraordinary diversity of forms among the 170+ species, from squat, ground-hugging detritivores to tall, arcing vines; some with tiny speckled traps like miniature wine glasses, others grown beastly with sharp, hook-lined gullets that drown rodents, and some remarkable species bearing pitchers that serve as roosts for bats.

Can Nepenthes Be Grown Like a Houseplant?

Many common varieties of Nepenthes originate where common houseplants originate, so they will grow spectacularly on sunny windowsills. Unobstructed windowsills facing south, east, or west are appropriate, the main concern being ample sunlight.

You may be able to grow Nepenthes outside if you live in a subtropical climate, like San Diego or Miami. Many can take brief overnight chills down to 40°F (4°C), but the daytime temperature should be in the mid-70s. Always avoid frost.

How Much Light Do Nepenthes Need?

Provide partial sunlight, several hours of unobstructed, direct sun with bright filtered light during the rest of the day. Avoid full shade.

Sunlight is the key element in getting your plant to grow pitchers. The energy provided by photosynthesis is what grows pitchers, and sunlight is essential for pitcher production and good color. With proper sunlight, many Nepenthes can be grown as regular houseplants.

What LED Lights Should I Use to Grow Nepenthes?

If a sunny window is not available, use LED shop lights with an output of at least 2,500 lumens. We prefer white LED shop lights rather than lights with red and blue diodes. In our experience, the red and blue lights can cause eye strain, and we haven't found them necessary for healthy plant growth. Start with the lights approximately 12 inches above the plant. Monitor your plant and adjust the height of the light source if you are not satisfied with its growth. Use an electrical timer to maintain a 14-hour daylight cycle.

What Temperatures Do Nepenthes Need?

Chances are if you’re comfortable in jeans and a t-shirt, your Nepenthes are comfortable, so it’s not necessary to fret about the temperature. They grow well when the day temperature is in the 70s (22°-26°C) with a nighttime drop into the 60s (16°-20°C), common temperatures many houseplants thrive in. Avoid frost and prolonged exposures of temperatures in the 40s (6°-10°C).

How Much Humidity Do Nepenthes Need?

For most commonly grown Nepenthes, humidity is far less important than adequate light and suitable temperatures. Established plants can acclimate to normal household humidity and produce healthy pitchers without a terrarium, humidifier, or humidity dome.

Humidity is not irrelevant. When the plant’s other growing requirements are met, higher humidity may produce somewhat larger leaves and pitchers. However, high humidity will not compensate for inadequate light, unsuitable temperatures, poor watering practices, or unhealthy roots, nor does it drive pitcher production the way sunlight and temperature do.

Why does our advice differ from what others say about Nepenthes and humidity?

We don't just accept common assumptions about plant care. We put them to the test. Watch our videos about our experience growing Nepenthes in normal household humidity and find out what the actual role humidity has on Nepenthes:

How Do I Water a Nepenthes?

Unlike many other carnivorous plants, most commonly grown Nepenthes are relatively tolerant of water containing higher mineral levels. They can generally tolerate water up to approximately 200 ppm when watered thoroughly from above and allowed to drain completely. For the simplest and safest recommendation, use rainwater, distilled water, reverse-osmosis water, or tap water containing 50 ppm or less of dissolved minerals.

Always water thoroughly until the entire potting mix is saturated, and allow the excess water to drain completely. Do not leave the pot standing in water. Constantly saturated conditions reduce aeration around the roots and can lead to root problems. Water again when the upper layer of the potting mix begins to lose moisture, but before it dries completely.

What Soil Do Nepenthes Need?

Use a mix of 1 part dried sphagnum moss and 1 part perlite. Moisten the ingredients thoroughly before potting up your plant. Avoid using potting soil and compost, as their nutrient and mineral ingredients can kill carnivorous plants.

When Should I Repot My Nepenthes?

Nepenthes don't need to be repotted on a fixed schedule. Repot when the plant looks too large for its container or when the potting mixture has begun to break down, become compacted, or no longer drains well.

Choose a pot with drainage holes that is appropriately sized for the plant. Avoid using an excessively large container, which can hold more water than the plant needs. Repot using the same mixture recommended above: 1 part dried sphagnum moss to 1 part perlite.

Nepenthes have relatively fine roots, so handle the root system gently and avoid unnecessarily removing potting material that is firmly attached to healthy roots. Position the plant at approximately the same depth at which it was previously growing, water thoroughly, and allow excess water to drain.

Some temporary slowing of growth after repotting is normal. Return the plant to its usual growing conditions and avoid making additional major changes to its environment while it becomes established in the new pot.
