Light
Bright light. A few hours of direct or filtered sun near a window works well, or a strong grow light on a 12 to 14 hour photoperiod. Insufficient light is the most common reason a Nepenthes doesn't form pitchers.
Soil
1 part long-fibre sphagnum moss to 1 part perlite. Orchid bark can be added to the mix, further improving aeration and providing a damp medium for roots to secure to.
The species and hybrids we sell are quite hardy, and also grow well in a simple 1 part peat moss to 1 part perlite mix. This can be a more affordable option and easier to source than sphagnum moss.
Use plastic or glazed pots rather than unglazed terracotta, which dries out fast and can slowly leach minerals into the mix.

Water
Keep media damp using rainwater, distilled water, or reverse osmosis water. Top-watering is closest to how they grow in the wild, but a shallow tray works too and is easier to manage. Keep the water level very shallow, just enough to dampen the base of the pot. Let it sufficiently dry out for a few days before adding more. Avoid leaving it in deep water for long stretches, which can lead to root rot.

Beneficial, but not essential. The species and hybrids we sell will pitcher in ordinary household humidity, given sufficient light. Higher humidity produces larger, longer-lasting pitchers.
Temperature
Comfortable at normal household temperatures. The species and hybrids we sell have no frost tolerance, so keep them indoors or bring them in well before the first frost.
Dormancy
None needed. Nepenthes are tropical plants and grow year round. They slow down a little over winter as natural light drops and temperatures cool, but they don't go properly dormant.
Feeding & Fertilizer
A diluted liquid fertilizer misted onto the leaves, or into a pitcher, once or twice a month is plenty. Live or dried insects can also go straight into a pitcher. Very light root fertilization can be practiced by experienced growers.
Once an insect lands, it has little chance of escape. The slippery rim and waxy inner walls give it nothing to grip, and some species have a thick digestive fluid that coats anything falling in, making movement and flight almost impossible.
Pruning & Repotting
Trimming
Trim pitchers and leaves off once they've gone fully brown. Most pitchers last a few months before naturally dying back, and they keep digesting insects even as the top starts to brown. A simple rule of thumb: if you can't stand to look at it, cut it off. If you prefer a pristine-looking plant, feel free to trim them sooner.
New shoots
Nepenthes are vining plants that climb toward the sun in the wild. As they grow, they'll often send up a new shoot from the base. Once that shoot has rooted in well on its own, you can cut it away from the main vine and pot it up as a new plant. If a vine gets long and leggy, cut it back just above a leaf. This encourages the plant to push new growth from lower down and keeps it more compact.
Repotting
Repot every few years into fresh media, or whenever the old media becomes compacted or stops draining freely. Nepenthes don't mind being a little root-bound, so only size up the pot once the roots have filled it.
