Aglaomorpha coronans, commonly known as the Ribbon Fern or King Fern, is a captivating fern species that can thrive in a terrarium environment. Follow these care guidelines to provide the best conditions for your Aglaomorpha coronans in a terrarium:
Terrarium Setup:
Terrarium Type: Choose a glass or acrylic terrarium with a lid to create a closed, humid environment. A medium-sized terrarium is suitable to accommodate the fern's growth.
Substrate: Use a well-draining substrate mixture. A blend of orchid bark, sphagnum moss, and perlite or a specialized fern mix works well. Ensure the substrate is consistently moist but not waterlogged.
Lighting: Aglaomorpha coronans prefers bright, indirect light. Position the terrarium near a bright window with filtered sunlight or use artificial grow lights. Aim for 10-12 hours of light per day.
Temperature and Humidity: Maintain a temperature range of 65°F to 75°F (18°C to 24°C) with high humidity levels between 50% to 70%. Utilize a hygrometer to monitor humidity levels and a thermostat to regulate temperature if necessary.
Watering:
Watering Frequency: Keep the substrate consistently moist but not soggy. Water when the top inch of the substrate feels slightly dry. Depending on your terrarium's conditions, this may be once or twice a week.
Water Quality: Use distilled or rainwater to prevent the accumulation of minerals that can harm the fern. Ensure that the water is at room temperature to avoid shocking the plant.
Fertilization:
Fertilizer Type: Aglaomorpha coronans doesn't require frequent fertilization. Use a balanced, liquid, or water-soluble fertilizer diluted to half or quarter strength. Apply it every 6-8 weeks during the growing season (spring and summer).
Fertilizing Schedule: Reduce or cease fertilization during the fall and winter when the plant's growth slows down.
Pruning and Maintenance:
Pruning: Trim any yellowing or dead fronds to encourage new growth and maintain the plant's appearance.
Cleaning: Regularly remove any fallen leaves or debris to keep the terrarium clean.
Propagation:
Aglaomorpha coronans can be propagated through division or spores. Division is the simpler method. Gently separate the plant into smaller sections, each with roots and fronds, and plant them in the substrate.
Common Issues:
Drying Out: Insufficient humidity or underwatering can cause Aglaomorpha coronans to dry out. Maintain proper humidity levels and monitor the substrate's moisture regularly.
Yellowing or Browning: This may indicate overwatering or inadequate drainage. Adjust your watering routine and ensure that the terrarium has proper drainage.
Pests: Watch for pests like mites or scale insects. Isolate any affected plants and promptly treat them with neem oil or insecticidal soap.
Final Tips:
Avoid overcrowding the terrarium with too many plants, as this can hinder air circulation and increase the risk of disease.
Aglaomorpha coronans can benefit from occasional misting to boost humidity levels within the terrarium.
With proper care and attention, Aglaomorpha coronans will flourish in your terrarium, adding an exquisite and unique touch with its distinctive ribbon-like fronds.
