Coleus 'Alligator' Care Sheet for Terrariums

Introduction: Coleus 'Alligator' (Plectranthus scutellarioides 'Alligator') is a vibrant and ornamental plant known for its striking foliage patterns. When grown in a terrarium, 'Alligator' adds a splash of color and texture. Follow these care guidelines to ensure the health and vibrancy of your Coleus 'Alligator' in a terrarium:

1. Terrarium Setup:

  • Use well-draining, nutrient-rich potting soil suitable for indoor plants in your terrarium. Ensure the terrarium has proper drainage.

2. Light:

  • Provide bright, indirect light for Coleus 'Alligator.' It can tolerate some direct sunlight, but too much can lead to leaf burn.
  • Adjust the light levels based on the color intensity of the foliage. Higher light levels often enhance the vivid patterns.

3. Temperature and Humidity:

  • Maintain a temperature range between 65-75°F (18-24°C). Coleus prefers warmer conditions.
  • Keep the humidity levels in the terrarium between 50-60%. Coleus generally thrives in moderately humid environments.

4. Watering:

  • Keep the soil consistently moist but not waterlogged. Water when the top inch of the soil feels slightly dry.
  • Water at the base of the plant to avoid wetting the leaves, which can reduce the risk of fungal issues.

5. Fertilization:

  • Feed Coleus 'Alligator' with a balanced liquid fertilizer every 2-4 weeks during the growing season (spring and summer).
  • Use a well-balanced, water-soluble fertilizer with a formulation suitable for foliage plants.

6. Pruning and Maintenance:

  • Pinch or trim the growing tips regularly to encourage bushier growth and prevent the plant from becoming leggy.
  • Remove any yellowing or damaged leaves to maintain a neat appearance.

7. Air Circulation:

  • Ensure good air circulation within the terrarium to prevent the development of mold or mildew. Provide occasional ventilation by opening the terrarium lid.

8. Monitoring for Pests:

  • Keep an eye out for common pests such as aphids or spider mites. Treat any infestations promptly with insecticidal soap or neem oil.

9. Repotting:

  • Repot Coleus 'Alligator' if it outgrows its container or becomes root-bound. Choose a slightly larger pot and refresh the soil during repotting.

10. Terrarium Companions:

  • Coleus 'Alligator' can be combined with other compatible terrarium plants, but ensure they have similar light and moisture requirements.

By following these care guidelines, you can create an optimal environment for your Coleus 'Alligator' in a terrarium. The plant's colorful and patterned foliage will contribute to a lively and visually appealing indoor garden.
