are Sheet for Selaginella wallichii (Wallich's Spikemoss) in a Terrarium

Selaginella wallichii, commonly known as Wallich's Spikemoss, is a small, creeping fern ally that is often used as a decorative plant in terrariums or vivariums. It is native to tropical and subtropical regions of Asia and is known for its lush green foliage and trailing growth habit. Here are some care guidelines to help you successfully cultivate and maintain Selaginella wallichii in your terrarium:


  • Selaginella wallichii prefers bright, indirect light. Place your terrarium in a location with moderate to bright, filtered light. Avoid placing it in direct sunlight, as it can cause leaf burn or excessive drying of the foliage.


  • Selaginella wallichii thrives in high humidity environments. Mist the terrarium regularly to maintain humidity levels between 50-70%. You can also use a humidity gauge to monitor the humidity levels and adjust as needed. Providing a terrarium cover or lid can help to trap moisture and create a humid microclimate for the plant.


  • Selaginella wallichii prefers warm temperatures. Keep the terrarium at a temperature range of 70-80°F (21-27°C) during the day and 60-70°F (15-21°C) at night. Avoid sudden temperature drops or drafts, as it can stress the plant.


  • Selaginella wallichii prefers a well-draining substrate. Use a mix of sphagnum moss, orchid bark, and perlite to create a loose, well-aerated substrate that retains moisture without becoming waterlogged. Avoid using soil-based substrates, as they can retain too much moisture and cause root rot.


  • Selaginella wallichii prefers to be kept evenly moist, but not waterlogged. Water the terrarium thoroughly when the top inch of the substrate feels slightly dry. Use filtered or distilled water to avoid the buildup of chemicals or minerals. Avoid allowing the plant to sit in standing water, as it can lead to root rot.

Air Circulation:

  • Adequate air circulation is important for Selaginella wallichii to prevent the growth of mold or mildew. Avoid overcrowding the terrarium and ensure that there is some airflow through the terrarium to promote healthy growth and prevent stagnant air.


  • Selaginella wallichii can be pruned to control its trailing growth habit and encourage bushier growth. You can trim back overgrown or yellowing foliage using clean, sterilized scissors or pruning shears. Prune selectively to maintain the desired shape and size of the plant.


  • Selaginella wallichii is a trailing plant that can be used as a ground cover or allowed to climb up hardscape or background in a terrarium. It is a good fit for tropical or woodland-themed terrariums and can provide a lush, carpet-like effect when allowed to spread and grow.


  • Selaginella wallichii is generally compatible with other terrarium plants that have similar humidity and light requirements. It can be used in combination with other tropical plants, such as ferns, bromeliads, and orchids, to create a diverse and visually appealing terrarium.

Potential Challenges:

  • Maintaining the right humidity levels can be a challenge in some environments. Regular misting and monitoring of humidity levels are essential to prevent the plant from drying out or becoming waterlogged.
  • Overwatering or poor drainage can lead to root rot or fungal issues. Ensure that the substrate is well-draining and allow the top layer to dry slightly between waterings to prevent
