Minuartia verna Care Sheet for Open and Succulent Terrariums

General Information

Minuartia verna, also known as spring sandwort, is a hardy, low-growing perennial that thrives in alpine and rocky environments. It is well-suited for terrariums that replicate its natural habitat conditions, especially open and succulent terrariums.

Light Requirements

  • Open Terrarium: Place the terrarium in a location where it can receive bright, indirect light. Direct sunlight for a few hours a day is beneficial but avoid prolonged exposure which can cause overheating.
  • Succulent Terrarium: Similar to an open terrarium, ensure the plant receives plenty of bright, indirect light. Using a grow light can help maintain consistent lighting conditions, especially in indoor settings.

Soil and Drainage

  • Soil: Use a well-draining soil mix, such as a cactus or succulent mix. You can also create a custom mix by combining regular potting soil with sand or perlite to improve drainage.
  • Drainage Layer: Add a layer of small stones or gravel at the bottom of the terrarium to facilitate proper drainage and prevent root rot.


  • Open Terrarium: Water sparingly. Allow the soil to dry out completely between waterings. Overwatering can lead to root rot, so it's better to err on the side of underwatering.
  • Succulent Terrarium: Follow the same watering guidelines as for an open terrarium. Use a spray bottle to lightly mist the soil or water directly at the base of the plant, avoiding the leaves to prevent mold growth.


  • Open Terrarium: Minuartia verna prefers low humidity. Ensure good air circulation by keeping the terrarium open or using a terrarium with ample ventilation.
  • Succulent Terrarium: Maintain low humidity levels by avoiding overwatering and ensuring the terrarium has good airflow. If the humidity is too high, consider using a small fan or placing the terrarium in a less humid room.


  • Open Terrarium: This plant thrives in cooler temperatures, ideally between 60-70°F (15-21°C). Avoid placing the terrarium in areas that experience high heat or sudden temperature fluctuations.
  • Succulent Terrarium: Maintain similar temperature conditions as for an open terrarium. Ensure the terrarium is not exposed to direct heat sources like radiators or intense sunlight for prolonged periods.


  • Open Terrarium: Fertilize sparingly. Use a diluted, balanced liquid fertilizer (such as 10-10-10) once during the growing season (spring to early summer). Over-fertilizing can harm the plant.
  • Succulent Terrarium: Apply the same fertilization routine as for an open terrarium. Be cautious with the amount and frequency of fertilization to prevent nutrient buildup.


  • Pruning: Trim dead or yellowing leaves to promote healthy growth and prevent mold.
  • Pests: Minuartia verna is relatively pest-resistant, but keep an eye out for common terrarium pests like aphids or mealybugs. Treat infestations promptly with insecticidal soap or neem oil.

Additional Tips

  • Open Terrarium: Regularly monitor the terrarium for signs of mold or pests. Adjust watering and ventilation as needed to maintain a healthy environment.
  • Succulent Terrarium: Ensure the succulent terrarium has adequate drainage and avoid overcrowding the plants to promote air circulation and prevent excessive humidity.

By following these care guidelines, Minuartia verna can thrive in both open and succulent terrariums, bringing a touch of alpine beauty to your indoor garden.
