All Nepenthes grow best in continuously warm, humid, and bright conditions. Choose a variety that best matches your growing conditions. Highland species will tolerate cool winters. Lowland species like it hot, humid and bright year round. Heated greenhouses and terrariums can provided an excellent home habitat. Young plants can grow very slowly, even seem to sleep for years, and then grow vigorously. Others take off right away. Tropical Pitchers Plants can be challenging Carnivorous Plants to grow because of their need for consistently bright, humid and warm conditions. This often requires a greenhouse for sustained culture. Tropical Pitcher Plants prefer good air circulation and a light, well-drained, porous soil. A soil mix of peat, sand, perlite, orchid bark, and chopped Sphagnum works well. Pure live sphagnum moss or “orchid mix” is a good soil alternative. Nepenthes are tolerant of a variety of soil mixes. Keep the soil evenly moist and well drained. Water with mineral-free water from overhead. Mature Nepenthes prefer a hanging pot, basket or plant stand. They like bright, full sun and high humidity. Lowland species prefer hot days and warm nights, and highland species prefer warm days and cooler nights. A day/night temperature difference of 15°F (8°C) is recommended. A misting system is beneficial. Browning of traps or traps not forming is usually a sign of humidity that is too low. This can be remedied by growing in a large clear, vented plastic bag while new pitchers form, and removed once traps are mature. Mature Nepenthes are climbing vines and growing accommodations should provide for this. They like consistently moist, but draining soil. Water the soil, not the traps, though keeping a small amount,1/2" (1cm) of water in the trap will help it through hot, dry spells. One convenient way to water the whole plant, is to lower the pot into a bucket of water and let it thoroughly soak. Though they prefer mineral free water, they can tolerate occasional tap water more than other Carnivorous Plants. High humidity and good ventilation are important, even in a terrarium. If your conditions are a bit dry, consider frequent misting. Repot with fresh soil mix every few years. Tropical Pitchers Plants do not require dormancy. They prefer warm, humid winter conditions. Slow growth during the winter months is typical.
