Overview
Murdannia loriformis, known for its attractive foliage and medicinal properties, is an excellent choice for open terrariums. Its resilience and adaptability make it ideal for creating a miniature garden within glass containers, where it can thrive with proper care.
Light Requirements
Optimal Light: Prefers bright, indirect sunlight.
Placement: Position the terrarium in a location where it can receive ample indirect light. Avoid direct sunlight to prevent overheating and leaf burn.
Watering
Frequency: Water moderately, ensuring the soil remains consistently moist but not waterlogged.
Method: Water the plant thoroughly when the top layer of soil feels dry. Use a spray bottle to mist the soil, being careful not to oversaturate.
Soil
Type: Well-draining, lightweight terrarium soil mix.
Composition: A mix of peat, perlite, and sand ensures good drainage and prevents root rot.
Temperature and Humidity
Temperature: Thrives in temperatures between 60-85°F (15-29°C). Keep the terrarium in a stable environment away from drafts and temperature extremes.
Humidity: Prefers higher humidity levels typical of a terrarium environment. Mist the plants occasionally to maintain humidity.
Fertilization
Type: Use a diluted, balanced, water-soluble fertilizer.
Frequency: Fertilize lightly every 4-6 weeks during the growing season (spring and summer). Avoid over-fertilizing.
Pruning and Maintenance
Pruning: Trim back any overgrown or leggy stems to maintain the desired shape and size within the terrarium.
Cleaning: Wipe the inside of the terrarium glass periodically to ensure light penetration and prevent mold growth.
Propagation
Method: Propagate by stem cuttings directly within the terrarium.
Steps:
Take a cutting with at least 2-3 nodes from a healthy plant.
Remove the lower leaves and plant the cutting in the moist soil of the terrarium.
Keep the terrarium in a warm, bright area until roots develop.
Pests and Diseases
Common Pests: Rare in a terrarium setting, but watch for aphids, spider mites, and mealybugs.
Treatment: Use insecticidal soap or neem oil if pests appear.
Diseases: Root rot can occur if overwatered. Ensure proper drainage and avoid waterlogging the soil.
Special Notes
Medicinal Use: Murdannia loriformis is known for its medicinal properties, especially in traditional Thai medicine.
Aesthetic Appeal: Its compact size and attractive foliage make it a visually appealing addition to terrariums.
Troubleshooting
Yellow Leaves: May indicate overwatering or poor drainage. Adjust watering habits and ensure soil drains well.
Leggy Growth: Indicates insufficient light. Move the terrarium to a brighter location.
Slow Growth: May need more light or occasional feeding with a diluted fertilizer.
