Terrarium for Moss

Choosing the Right Terrarium Container

  1. Closed Terrariums: Closed terrariums create a high-humidity environment, ideal for moss species that thrive in moist, shaded environments. The closed environment helps trap moisture, reducing the need for frequent watering. Jars with lids, glass globes, and even old fishbowls make great choices for closed terrariums.
  2. Open Terrariums: Open terrariums provide better airflow and are suitable for moss types that can handle lower humidity levels. These terrariums also offer a little more flexibility in design, making them great if you want to add other plants that prefer slightly less humidity.
  3. Recycled Glassware: Using glassware you already own, like mason jars or glass bottles, can make this project even more sustainable. Ensure that the container is clear, as moss needs indirect light to grow.

Selecting Moss for Your Terrarium

  1. Sheet Moss (Hypnum): Known for its velvety texture and bright green color, sheet moss forms a beautiful carpet across the terrarium. It works well in closed terrariums because it loves high humidity.
  2. Cushion Moss (Leucobryum): This moss forms small, soft mounds that add a unique texture to the terrarium. Cushion moss grows well in high humidity but can also handle slightly drier conditions, making it versatile.
  3. Fern Moss (Thuidium): Fern moss creates a lacy, textured look with its fern-like appearance. It does best in closed terrariums due to its high moisture needs.
  4. Reindeer Moss (Cladonia): Technically a lichen rather than moss, reindeer moss adds a unique, branching structure and looks stunning in open terrariums where it gets plenty of airflow.
  5. Java Moss (Taxiphyllum barbieri): Although commonly used in aquariums, Java moss can also thrive in a terrarium. It prefers a humid environment, making it a great addition to closed terrariums.

Preparing Your Terrarium for Planting

  1. Base Layer: Start with small pebbles or gravel at the bottom of the terrarium. This layer helps excess water drain away from the moss and reduces the risk of root rot if you add other small plants.
  2. Charcoal Layer: A thin layer of activated charcoal goes on top of the gravel. Charcoal helps absorb excess moisture and prevents odors or fungal growth, which is especially important in closed terrariums.
  3. Soil Layer: Spread a layer of potting soil or a peat moss mix, just deep enough for the moss to anchor. Moss doesn’t require rich soil, so regular potting soil or coconut coir works well.

Planting the Moss

Caring for Your Moss Terrarium

  1. Watering: Moss needs consistent moisture to stay lush, but the amount depends on the type of terrarium. For closed terrariums, you may only need to mist every two weeks since they naturally retain moisture. Open terrariums require more frequent misting, usually once or twice a week. Mist the moss lightly, aiming for damp but not soaked conditions.
  2. Lighting: Moss prefers indirect sunlight or filtered light. Direct sunlight can cause the glass in a closed terrarium to heat up, harming the moss. A north-facing window or an area with diffused light works well. If your space lacks natural light, consider using a low-intensity grow light.
  3. Humidity: Closed terrariums maintain high humidity, but for open terrariums, you might need to mist more often or place a shallow dish of water nearby to increase ambient humidity.
  4. Cleaning: Keep the glass clean to allow maximum light in. Use a soft cloth to wipe down the inside and outside of the terrarium every few weeks. Regular cleaning prevents dust buildup and allows your terrarium to shine.
  5. Trimming and Maintenance: Occasionally, moss may grow too tall or develop brown patches. Trim back any overgrowth with scissors and remove dead sections to keep the terrarium looking its best. Moss doesn’t need fertilizers, so avoid adding any, as this can disrupt its natural growth.
