Why Nepenthes Won't Pitcher on a Windowsill

Geerard (Belgium) has N. ventrata, Miranda, ventricosa, sanguinea on south windowsill—large leaves, no pitchers. Regular watering, misting 2×/week with rainwater.

Jacob Farin: Insufficient light. Need several hours direct sun daily. Cloudy winter = no pitchers (nursery same). Miranda should have reddish leaves in good light—green = too low. Summer: hang outdoors under tree (dappled morning, direct afternoon) for pitchering. Misting unnecessary for these varieties (only ultrahighland need it; daily misting required for effect).

Good Growing!
