Plant Overview:
Coleus 'Mini Gold' is a compact, colorful cultivar of the Coleus plant, known for its vibrant golden foliage. It is a popular choice for closed terrariums due to its small size and low maintenance requirements.
Light:
Place the terrarium in a location with bright, indirect light. Avoid direct sunlight as it can scorch the delicate foliage. LED grow lights can also be used to provide adequate light if natural light is limited.
Temperature:
Maintain a consistent temperature range between 65°F to 75°F (18°C to 24°C) within the terrarium. Coleus 'Mini Gold' thrives in typical room temperatures and should be protected from drafts or sudden temperature fluctuations.
Humidity:
Closed terrariums create a naturally humid environment, which is ideal for Coleus 'Mini Gold'. However, if condensation becomes excessive, briefly open the terrarium lid to allow excess moisture to evaporate. Aim to maintain moderate to high humidity levels.
Watering:
Water the plant sparingly, allowing the top inch of soil to dry out between waterings. Use a spray bottle to mist the foliage and soil lightly, ensuring even moisture distribution. Overwatering can lead to root rot, so it's crucial to avoid waterlogging the soil.
Soil:
Use a well-draining potting mix suitable for terrarium plants. A blend of peat moss, perlite, and vermiculite works well for Coleus 'Mini Gold'. Avoid compacted or heavy soils that retain too much moisture.
Fertilization:
Fertilize sparingly to avoid nutrient buildup in the closed terrarium environment. Use a diluted, balanced liquid fertilizer formulated for indoor plants. Apply fertilizer at half the recommended strength once a month during the growing season (spring to early autumn).
Pruning:
Regularly pinch back the growing tips to encourage bushier growth and prevent legginess. Remove any yellowing or dead leaves promptly to maintain the plant's health and appearance.
Pests and Diseases: Monitor the plant regularly for signs of pests such as aphids, mealybugs, or spider mites. Treat infestations promptly with insecticidal soap or neem oil. Good ventilation and proper watering practices can help prevent fungal diseases such as powdery mildew.
Terrarium Maintenance:
Periodically clean the terrarium glass to remove any dust or water spots that may obstruct light. Trim or remove any other plants that compete with Coleus 'Mini Gold' for space or light. Keep the terrarium lid closed to maintain the microclimate, but ventilate occasionally to prevent excessive humidity buildup.
By following these care guidelines, you can enjoy the beauty of Coleus 'Mini Gold' thriving in your closed terrarium for an extended period
