Sedum 'Little Master' Care Sheet for an Open Terrarium

Overview: Sedum 'Little Master' is a charming, low-maintenance succulent perfect for open terrariums. With the right care, it will thrive and add a touch of greenery to your space.

Light Requirements:

  • Light: Place your open terrarium in a location where it will receive bright, indirect sunlight. Sedums need plenty of light to maintain their vibrant colors and compact growth.
  • Supplementary Lighting: If natural light is insufficient, consider using a grow light. Aim for about 12-14 hours of light per day.

Temperature and Humidity:

  • Temperature: Sedum 'Little Master' prefers temperatures between 60-75°F (15-24°C). It can tolerate higher temperatures if well-ventilated.
  • Humidity: Keep the environment dry. Open terrariums naturally have better air circulation, which is ideal for succulents. Avoid placing the terrarium in areas with high humidity.


  • Frequency: Water sparingly. Allow the soil to dry out completely between waterings. Typically, watering once every 2-3 weeks is sufficient.
  • Method: Water the soil directly, avoiding the foliage to prevent rot. Use a spray bottle or a small watering can for controlled watering.


  • Type: Use a well-draining succulent or cactus mix. You can also create your own mix by combining regular potting soil with perlite or sand (in a 2:1 ratio).
  • Drainage: Ensure your terrarium has a drainage layer at the bottom. Use pebbles, small rocks, or activated charcoal to help with water drainage and prevent root rot.


  • Frequency: Fertilize sparingly, about once every 2-3 months during the growing season (spring and summer).
  • Type: Use a balanced, water-soluble fertilizer diluted to half strength. Too much fertilizer can harm succulents.

Pruning and Maintenance:

  • Pruning: Remove any dead or yellowing leaves to keep the plant healthy and prevent disease. Trim back leggy growth to maintain a compact shape.
  • Repotting: If the plant outgrows its space, carefully repot it into a larger container with fresh soil.

Pests and Problems:

  • Pests: Watch for common pests like aphids, mealybugs, and spider mites. If you notice pests, treat the plant with insecticidal soap or neem oil.
  • Diseases: Avoid overwatering to prevent root rot and fungal infections. Ensure good air circulation to minimize the risk of disease.

Additional Tips:

  • Observation: Regularly check your plant for signs of stress, such as discoloration or wilting, and adjust care as needed.
  • Environment: Keep the terrarium in a stable environment, avoiding extreme temperature fluctuations and drafts.

By following these guidelines, your Sedum 'Little Master' will thrive in its open terrarium, adding beauty and a touch of nature to your space.
