Carnivorous Plant Terrariums: Why Simpler Is Usually Better

While terrariums seem appealing, they often complicate carnivorous plant care unnecessarily. Most species adapt well to lower humidity and thrive on sunny windowsills without elaborate enclosures.

The Problem with Terrariums

• High humidity promotes fungal and bacterial diseases.
• Cleaning a soil-filled terrarium after an outbreak means starting over.
• Inadequate lighting is the #1 cause of failure.

Better Approach: Potted Plants in Open Air

Grow plants in individual pots sitting in water trays on a sunny south windowsill. The evaporation provides ample humidity. This method is easier to maintain, cleaner, and healthier for the plants.

If You Still Want a Terrarium

• Use it as a display case for potted plants, not a soil bed.
• Provide strong lighting: 40+ watts of fluorescent (e.g., two 27W compact fluorescents).
• Keep it simple for easy cleaning.

Key Takeaway

More plants die from excessive humidity than from low humidity. Focus on light, water quality, and airflow. Our updated care sheets (coming soon) detail why open-air growing is superior for most species.
