Care Sheet: Begonia rex 'Silver' in Closed Terrarium
 
Begonia rex 'Silver' is a captivating plant known for its striking silver foliage, making it an excellent choice for a closed terrarium. Here's a care sheet to ensure your Begonia rex 'Silver' flourishes in this enclosed environment:
 
1. Terrarium Selection:
Choose a glass terrarium with a lid to create a controlled environment with high humidity. Ensure the terrarium has adequate ventilation to prevent mold and mildew.
 
2. Substrate and Drainage:
Use a well-draining, nutrient-rich substrate such as a mixture of peat moss, perlite, and orchid bark. Ensure there is a layer of drainage material, such as gravel or charcoal, at the bottom to prevent waterlogging.
 
3. Lighting:
Begonia rex 'Silver' thrives in bright, indirect light. Place the terrarium in a location with filtered sunlight or provide artificial grow lights for 10-12 hours a day.
Avoid direct sunlight, as it can scorch the delicate foliage.
 
4. Temperature and Humidity:
Maintain a consistent temperature between 65-75°F (18-24°C) within the terrarium.
Keep humidity levels high, ideally between 50-80%. Mist the terrarium occasionally to maintain moisture levels, but avoid over-saturation.
 
5. Watering:
Water the Begonia rex 'Silver' sparingly, allowing the top inch of soil to dry out between waterings.
Use room temperature water to prevent shock to the plant. Avoid overhead watering to prevent leaf damage and fungal issues.
 
6. Fertilization:
Feed the Begonia rex 'Silver' with a balanced, water-soluble fertilizer diluted to half strength every 4-6 weeks during the growing season (spring to early fall).
Reduce or eliminate fertilization during the dormant winter months.
 
7. Pruning and Grooming:
Trim any yellowing or dead leaves to maintain the plant's health and appearance. Prune leggy growth to encourage a compact habit.
Regularly remove debris and fallen leaves to prevent pests and diseases.
 
8. Pest and Disease Control:
Keep an eye out for common pests such as aphids, mealybugs, and spider mites. Inspect the plant regularly and treat any infestations promptly with insecticidal soap or neem oil.
Ensure good air circulation within the terrarium to prevent fungal diseases.
 
9. Monitoring:
Regularly inspect the Begonia rex 'Silver' for signs of stress, including wilting, yellowing leaves, or pest infestations. Address any issues promptly to prevent further damage.
With proper care and attention to its needs, Begonia rex 'Silver' will thrive and add a touch of elegance to your closed terrarium, delighting you with its shimmering foliage.
