Nepenthes sibuyanensis: Ground-Hugging Habit Demands Higher Humidity

Why No Pitchers?

N. sibuyanensis grows like N. ampullaria—pitchers on the forest floor. This habit correlates with high humidity needs. Your west window + lamp setup likely lacks sufficient ambient moisture.

Solutions

• Move to bright indirect light (floor spot was good).
• Create a partial enclosure (clear bag/dome) to raise humidity.
• May need a terrarium long-term—like N. ampullaria, N. bicalcarata.

Soil & Pot

Plastic pot + orchid mix/sphagnum is fine. Terra cotta dried too fast.

Outlook

This species may always need elevated humidity. Test enclosure—if pitchers form, you’ve found the key.
