Nepenthes Not Pitchering in Bagged Greenhouse Window: Remove Bag, Add Patience

Brad has 4 Nepenthes (chaniana x veitchii, talangensis x ventricosa, (inermis x singalana) x mira, N. alata) in south greenhouse window (bright direct sun, bottom tier). No pitchers, leaves healthy, not withering. Plastic bag with holes over plants for humidity. Not sitting in water. Watering every few days.

Remove the Bag Immediately—It's a Death Trap

Never enclose plants in plastic under direct sun. Traps heat, kills plants. Even with holes—dangerous. We don't recommend this for anyone. Left photo = correct method.

Three Factors

1. Acclimation time — 1–2 months typical, up to 6 in extreme cases.
2. Winter dormancy — Nepenthes often stop pitchering in short days. Normal even for us. Spring recovery needed.
3. Light — Need couple hours direct + bright indirect. Box window orientation unknown. Leaves look shiny/healthy = likely just time.

Bag off, soil moist, proper light, then patience. Watch March video podcast (winter pitcher pause) and Vol. 3 for humidity methods that don't kill.

Good growing!
