How to grow a Moss Terrarium?

Before you start assembling your moss terrarium, gather all the necessary materials. Here’s a list of what you’ll need:

Glass container

Choose a glass container that is large enough to accommodate your moss and any decorative elements you may want to add. It should have a lid or be able to be covered to create a humid environment for your moss.

Activated charcoal

Activated charcoal is essential for maintaining the health of your moss terrarium. It helps to absorb any odors and toxins, keeping the environment clean and fresh.

Potting soil

Select a high-quality potting soil that is well-draining. Moss prefers a slightly acidic soil, so look for a mix that is suitable for acid-loving plants.


The star of your moss terrarium is, of course, the moss itself. You can either gather moss from your garden or purchase it from a reputable supplier. Look for different varieties of moss to create a visually interesting terrarium.

Decorative elements (optional)

If you want to add a personal touch to your moss terrarium, consider incorporating decorative elements such as small figurines, rocks, or miniature plants. These elements can enhance the overall aesthetic appeal of your terrarium.

Preparing the container

Now that you have gathered all the necessary materials, it’s time to prepare the container for your moss terrarium.

Wash and dry the container

Start by washing the glass container with warm soapy water to remove any dirt or residue. Rinse it thoroughly and allow it to dry completely before proceeding.

Add a layer of activated charcoal

Once the container is dry, add a layer of activated charcoal at the bottom. This layer will help to keep the terrarium clean and prevent any unpleasant odors.

Add a layer of potting soil

Next, add a layer of potting soil on top of the activated charcoal. Make sure the soil is evenly distributed and covers the entire bottom of the container.

Planting the moss

Now it’s time to plant the moss in your terrarium.

Separate the moss into small pieces

Take the moss you gathered or purchased and separate it into small pieces. This will allow you to distribute it evenly throughout the terrarium.

Place the moss on top of the soil

Gently place the moss pieces on top of the soil, ensuring that they are evenly spread out. You can arrange them in any pattern or design you prefer.

Press the moss gently into the soil

Once the moss is in place, lightly press it into the soil to ensure good contact and promote root establishment. Be careful not to press too hard and damage the delicate moss.

Caring for your moss terrarium

Caring for your moss terrarium
To ensure the health and longevity of your moss terrarium, proper care is essential.


Moss thrives in a moist environment, so it’s important to keep the terrarium evenly moist. Use a spray bottle to mist the moss regularly, ensuring that it doesn’t dry out or become waterlogged.


Moss prefers indirect or filtered light. Place your terrarium in a location where it will receive bright, indirect light, such as near a window but not in direct sunlight. Avoid placing it in dark or dimly lit areas.

Temperature and humidity

Moss thrives in cool, humid conditions. Aim to keep the temperature between 60-75°F (15-24°C) and maintain a humidity level of around 50-60%. If the air in your home is dry, you can use a humidifier or place a tray of water near the terrarium to increase humidity.

Adding decorative elements (optional)

If you want to add some extra flair to your moss terrarium, now is the time to do so. Consider adding small figurines, rocks, or miniature plants to create a whimsical and personalized display.

Troubleshooting common issues

While moss terrariums are relatively low-maintenance, they can encounter a few common issues.

Mold or fungal growth

If you notice mold or fungal growth in your terrarium, it’s a sign of excessive moisture. Reduce watering and increase airflow by removing the lid or opening it slightly to allow for better ventilation.

Browning or yellowing moss

Browning or yellowing moss is often a sign of inadequate lighting or overwatering. Adjust the lighting conditions and reduce watering if you notice these issues.

Overwatering or underwatering

Finding the right balance of moisture is crucial for moss terrariums. Overwatering can lead to root rot and other issues, while underwatering can cause the moss to dry out. Monitor the moisture levels and adjust your watering routine accordingly.

Conclusion on How to grow a Moss Terrarium

Growing a moss terrarium is a rewarding and enjoyable experience. By choosing the right container, gathering the necessary materials, and following the proper care guidelines, you can create a beautiful and thriving moss terrarium that will bring a touch of nature into your home.

Remember to personalize your terrarium with decorative elements and troubleshoot any issues that may arise. Happy terrarium gardening!
