Managing Mexican Butterwort (Pinguicula) Dry Dormancy in a Cool Greenhouse

Trigger Recognition

Overnight lows of 50°F (10°C) and shortening days trigger the succulent winter rosette. The plant pulls in carnivorous leaves and forms a tight, non-carnivorous center.

Care During Dry Phase

• Reduce watering: keep soil barely damp, not wet.
• Remove from water tray.
• Maintain for ~1 month, then resume normal watering as temps rise.

Greenhouse Advantage

Your 50-80°F range is ideal; the plant will cycle naturally. No forced manipulation needed.
