Most Nepenthes enjoy very bright, diffused light or partly sunny conditions. Many can be grown easily on a sunny windowsill. Terrariums with high-powered fluorescent or LED lights are easy to set up and ideal. Nepenthes require at least three hours of direct light if grown indoors on a windowsill. If you notice your plant has stopped making pitchers, it is often a sign that the plant needs a bit more light or more humidity.
In greenhouses avoid the tray method of watering entirely and place the containers on benches or hang them so water can freely drain away. In terrariums and on windowsills, place the pot in a shallow saucer and water overhead as soon as the water in the saucer evaporates. Don’t allow the pot to sit in deep water for extended periods of time as this can lead to root rot. Make sure all pots have drainage holes. Misting plants several times a day will help with, but not provide enough moisture for this species. Be sure to pour water through the pot and soil mix frequently to make sure all the mix remains moist, but not waterlogged.
Water should be mineral free, such as rain, distilled or reverse osmosis. More details are available on this page (Link).
Temperature and Dormancy:
All Nepenthes are tropical plants, roughly divided into two categories called lowlanders and highlanders.
- Lowlanders come from low elevations in tropical Southeast Asia. Constant temperatures in 80’s F with high humidity is ideal, although some species will grow on sunny windowsills in warm homes. They are not tolerant of low temperatures. They do not like a night time temperatures to drop below 70 F.
- Highlanders do best with day temps in 70 – 80’s F. They require a night time drop in temperature of about 10-20 F degrees to the 50 – 60’s F in order to thrive. Most highlanders can be easily grown on sunny windowsills. They can be damaged or killed by temperatures below 50 F and in direct sun outdoors in high heat.
Nepenthes do not require a dormancy period.
Nepenthes enjoy loose, open soil that remains wet but allows drainage of excess water. They are tolerant of a wide variety of soil mixes. More information about their soil, and various mixes can be reviewed on my soil page here (Link).
Feeding and Fertilizer:
Maxsea fertilizer can be applied monthly, to the leaves and into the pitchers of the plant. Avoid pouring through the soil. Dilute 1/4 teaspoon MaxSea into 1 gallon of water for you can use Osmocote 16-16-16 fertilizer pellets as well. Put one pellet into each new pitcher as it opens. Additional info on fertilizing an be viewed here (Link) and both fertilizers are available on my store as well (Link).
