Coleus Fairway Mosaic Care Sheet for Closed Terrariums


1. Terrarium Setup:

  • Container: Use a glass terrarium with a lid to maintain humidity.
  • Substrate: Use a well-draining potting mix suitable for tropical plants.
  • Humidity: High humidity is essential; aim for 60-80% humidity levels.
  • Light: Indirect light or filtered sunlight is ideal. Avoid direct sunlight to prevent leaf burn.


2. Watering:

  • Moisture Levels: Keep the soil evenly moist but not waterlogged. Ensure proper drainage to prevent root rot.
  • Watering Frequency: Check the soil moisture regularly; water when the top inch of soil feels dry.
  • Watering Method: Use a spray bottle or watering can with a fine nozzle to water gently and evenly.


3. Temperature and Environment:

  • Temperature Range: Coleus Fairway Mosaic prefers temperatures between 65-75°F (18-24°C). Avoid sudden temperature fluctuations.
  • Ventilation: Terrariums can sometimes trap heat; ensure adequate airflow by occasionally opening the lid for ventilation.


4. Fertilizing:

  • Frequency: Feed the plant every 4-6 weeks during the growing season (spring through early fall).
  • Type of Fertilizer: Use a balanced, water-soluble fertilizer diluted to half strength.


5. Pruning and Maintenance:

  • Pruning: Regularly pinch back growing tips to encourage bushiness and prevent legginess.
  • Removing Dead Leaves: Remove any yellow or dead leaves promptly to maintain plant health.


6. Pests and Diseases:

  • Monitor: Check regularly for signs of pests such as aphids, spider mites, or mealybugs.
  • Treatment: If pests are detected, isolate the plant and treat with insecticidal soap or a suitable pesticide.


7. Growth and Propagation:

  • Propagation: Coleus Fairway Mosaic can be propagated from stem cuttings. Root cuttings in water or directly in moist soil.
  • Managing Growth: Trim back excessively long stems to maintain compact growth within the terrarium.


8. Troubleshooting:

  • Yellowing Leaves: Could indicate overwatering or underwatering. Adjust watering accordingly.
  • Leggy Growth: Insufficient light can cause leggy growth; consider moving to a brighter location.


9. Replanting and Refreshing:

  • Replanting: Every 1-2 years, consider replanting in fresh soil to refresh nutrients and maintain plant health.
  • Cleaning: Clean the terrarium glass periodically to allow maximum light penetration.


By following these care guidelines, your Coleus Fairway Mosaic should thrive within the controlled environment of a closed terrarium, providing lush foliage and vibrant colors to enhance your indoor space.
