Nepenthes bicalcarata Shock: Acclimating to Lower Humidity

A bare-root N. bicalcarata from Borneo Exotics was potted in peat/perlite/vermiculite, placed in a south window, and misted. Leaves curled, hardened, blackened.

Cause: Humidity Shock

Sudden drop from near-100% greenhouse humidity to typical home air causes rapid transpiration loss – leaves can't supply water fast enough.

Emergency Care

1. Move away from window (no direct sun).
2. Cover with clear plastic cup/bag to create humidity dome.
3. Wait 2–4 weeks for new growth.
4. Then acclimate gradually over 2 weeks – increase venting daily.

Outcome Uncertain

Survival depends on root health. If new growth appears, proceed with slow acclimation. Volume 3 DVD details the process.
