Calathea (Maranta) rufibarba, (12cmPOT) also known as the Prayer Plant, is a popular choice for terrariums due to its stunning foliage and relatively low maintenance requirements. Here's a care sheet to help you cultivate Maranta rufibarba in your terrarium:
Light:
Maranta rufibarba thrives in medium to bright indirect light. Avoid direct sunlight, as it can scorch the delicate leaves.
Place your terrarium in a location where it can receive filtered light, such as near a north or east-facing window.
Temperature:
Maintain a consistent temperature between 65°F to 75°F (18°C to 24°C) within the terrarium. Maranta rufibarba prefers warm and humid conditions.
Avoid placing the terrarium near drafts or heating vents, as sudden temperature fluctuations can stress the plant.
Humidity:
Maranta rufibarba requires high humidity to thrive. Maintain humidity levels between 50% to 60% within the terrarium.
If the air in your home is dry, consider using a humidifier or misting the plant regularly to increase humidity levels.
Watering:
Keep the soil consistently moist but not waterlogged. Water the plant when the top inch (2.5 cm) of soil feels dry to the touch.
Use room temperature water to avoid shocking the plant. Ensure that excess water can drain freely from the terrarium to prevent waterlogging.
Soil:
Plant Maranta rufibarba in a well-draining, peat-based potting mix. A mix formulated for tropical plants or terrariums works well.
Ensure that the soil is loose and airy to allow for adequate drainage and root aeration.
Fertilization:
Feed Maranta rufibarba with a balanced liquid fertilizer diluted to half-strength every 4-6 weeks during the growing season (spring and summer).
Avoid fertilizing during the dormant season (fall and winter) when the plant's growth slows down.
Pruning and Maintenance:
Trim back any leggy or yellowing foliage to encourage bushier growth and maintain the plant's appearance.
Remove any dead or decaying leaves promptly to prevent the spread of disease.
Propagation:
Maranta rufibarba can be propagated easily through division. Simply separate the plant into smaller sections, ensuring that each section has healthy roots and shoots.
Plant the divisions in individual pots or directly into the terrarium soil, and provide them with appropriate care.
Pests and Diseases:
Keep an eye out for common pests such as spider mites, aphids, and mealybugs. Treat infestations promptly with insecticidal soap or neem oil.
Ensure good air circulation within the terrarium to prevent fungal diseases such as powdery mildew and leaf spot.
By following these care guidelines, you can successfully cultivate Maranta rufibarba in your terrarium, enjoying its vibrant foliage and unique growth habit.
