Water Parameters & Planting Recommendations

Ideal Water Parameters

• Temperature: 18-26°C
• pH: Slightly acidic to neutral (5.5-7.0)
• Water Type: Soft, dechlorinated water
• Humidity: 70-90%, essential for vigorous growth and flowering

Terrarium Planting Tips

• Substrate: Plant Utricularia sandersonii in a mix of nutrient-poor media, such as a combination of peat moss and silica sand, to mimic its natural habitat.
• Drainage: Ensure a layer of gravel or coarse sand at the base to prevent waterlogging.
• Lighting: Place in bright, indirect light or under low-wattage grow lights, avoiding direct sunlight which can scorch the leaves.

How to Harden Your Tissue Culture Utricularia sandersonii 'White Rabbit'

When transferring Utricularia sandersonii from its tissue culture cup, it is essential to harden it gradually to adapt to open-air conditions. Begin by opening the cup in a high-humidity environment, such as a terrarium, and allow indirect light exposure. Over the first week, leave the lid off for short periods, increasing the duration daily to help the plant adjust. Mist lightly to maintain high humidity, as bladderworts are sensitive to rapid humidity drops. After two weeks, the plant should be acclimated enough to thrive without the cup, ready to charm in its new setup.
