Terrariums are tiny, enclosed ecosystems that mimic the natural processes of the environment within a glass container. A self-sustaining terrarium is one that requires minimal maintenance as it can sustain itself through its own ecosystem. It is the perfect addition to any home decor, adding a touch of nature and freshness to your living space. Here we will learn How to Make a Self Sustaining Terrarium.
A self-sustaining terrarium is essentially a miniature garden that can regulate its own water cycle and nutrient levels. This means that you do not need to constantly water or fertilize it, making it an ideal option for those who want to have some greenery in their home but do not have the time or resources for constant upkeep.
The plants and soil within the terrarium create their own ecosystem, in which they recycle air and water through natural processes such as photosynthesis and transpiration. In other words, once you set up your self-sustaining terrarium correctly, it should be able to thrive without much intervention from you.
Benefits of having a self-sustaining terrarium
Apart from being low-maintenance, self-sustaining terrariums have many benefits. They are great for those who live in cities or in places with little outdoor greenery because they bring nature into your living space. Additionally, they are great stress-relievers as plants have been proven to reduce stress levels and improve mental wellbeing.
Self-sustaining terrariums can also help purify the air in your home by absorbing harmful pollutants such as benzene and formaldehyde from the atmosphere. They can even act as natural humidifiers by releasing moisture into dry indoor environments.

Brief overview of DIY guide How to Make a Self Sustaining Terrarium
In this DIY guide, we will show you how to make your very own self-sustaining terrarium from scratch. We will provide a list of materials needed and detailed instructions on how to set up your terrarium step by step.
We will also guide you on how to maintain your terrarium for long-lasting and thriving greenery in your home. So, let’s get started!
Materials needed
Creating a self-sustaining terrarium is not only an interesting hobby but also an excellent way of bringing the outdoors inside. The materials used in making a terrarium are fundamental to its success, and each plays a critical role in ensuring that the enclosed environment remains self-sustaining. Here are the essential materials needed for creating your very own terrarium:
Glass container with lid
The container is where all the magic happens. You will need a glass container with a lid that can be sealed or closed tightly to create an enclosed environment for your plants. Choose a clear glass container as it allows for maximum light exposure, which is crucial for photosynthesis and overall plant growth.
Gravel or pebbles
Gravel or pebbles are necessary for drainage purposes. These materials help to prevent waterlogging, which in turn reduces the possibility of mold and bacteria growth within the terrarium. Pebbles also add visual appeal and texture to your creation.
Activated charcoal
Activated charcoal has excellent filtering properties that help absorb impurities from water and air. It acts as nature’s filter by removing toxins such as chlorine, ammonia, and other harmful gases that could negatively affect plant growth within the enclosure.
Potting soil
Potting soil is suitable for most plants and provides essential nutrients necessary for their growth and development. Be sure to select high-quality potting soil that drains well, retaining enough moisture for plant roots without leading to waterlogging.
Plants (preferably small and low-maintenance)
Selecting appropriate plants is vital when creating a self-sustaining terrarium. Choose small plants that won’t outgrow your enclosure quickly or require frequent maintenance tasks such as pruning or watering. Low maintenance succulents or cacti work excellently because they thrive in high humidity and low light conditions.
Decorative elements (optional)
Adding decorative elements to your self-sustaining terrarium can enhance its overall aesthetic appeal. You can include rocks, figurines, or moss as decorative elements to create a more natural-looking environment for your plants. Keep in mind that any additions should not interfere with the plant’s growth or impede their access to light or nutrients.
Steps to create the terrarium

Creating a self-sustaining terrarium is not as complicated as it may seem. It requires some careful attention and patience, but once it’s established, it can last for years with minimal maintenance. Here are the steps to follow when creating your own self-sustaining terrarium:
1. Layering the bottom
The first step in building a self-sustaining terrarium is layering the bottom. This includes adding a layer of gravel or pebbles at the bottom of the container for drainage.
The layer should be about 1-2 inches deep, enough to allow drainage without taking up too much space. On top of the gravel layer, add a thin layer of activated charcoal.
This helps prevent mold and bacteria growth while also keeping odors at bay. Activated charcoal can be purchased online or at garden centers.
2. Adding soil and plants
After completing the bottom layering, it’s time to add potting soil on top of the charcoal layer. The depth should again be around 1-2 inches deep. The type of plants you choose plays an essential role in creating a self-sustaining terrarium ecosystem that thrives and survives on its own.
When selecting plants for your terrarium, choose small and low-maintenance ones such as ferns or succulents. When planting them in soil, make sure they have enough space between them so that they don’t compete for nutrients or water absorption from soil.
3. Decorating (optional)
Once you’ve planted your plants, it’s time to add decorative elements to enhance visual appeal if desired. Rocks or moss make excellent additions because they help keep moisture in while also contributing to aesthetic value. Alternatively, miniature figurines can help create an element of surprise when someone looks inside your self-sustaining terrarium.
However, keep in mind that adding too many decorative elements can make the environment crowded and difficult to maintain. Creating a self-sustaining terrarium is an exciting project that can be accomplished easily with the right materials and knowledge.
By following these steps, you can create a beautiful, low-maintenance ecosystem that enhances your living space while also improving air quality. Remember to monitor moisture levels and prune plants as needed to ensure your self-sustaining terrarium continues to thrive for years to come.
Maintenance
Watering:
Watering is an essential part of maintaining your self-sustaining terrarium, but it can also be tricky. Overwatering can lead to mold and bacterial growth, while underwatering can cause the plants to wilt and die.
To avoid these issues, you should monitor moisture levels by checking the condensation on the inside of the container. If there is excessive condensation, it means that there is too much water in the terrarium.
In this case, remove the lid of the container for a few hours to allow excess water to evaporate. When watering your self-sustaining terrarium, you should do so sparingly and only when necessary.
The amount of water required will depend on several factors such as the size of your container, temperature conditions and humidity levels in your environment. On average you should aim for once a month watering routine.
Pruning and cleaning:
Regular pruning and cleaning are necessary steps in maintaining a healthy self-sustaining terrarium. Dead leaves or overgrown plants can attract insects or fungi that could harm other plants in the terrarium if not removed promptly. To prune your plants use clean scissors or pruning shears that have been sterilized with rubbing alcohol before use.
Trim off any dead leaves or stems at their base to keep them from draining nutrients from healthy parts of the plant. Cleaning involves removing any external debris from around or inside your terrarium using a damp cloth or soft brush where necessary.
Conclusion
That is How to Make a Self Sustaining Terrarium. Creating a self-sustaining terrarium can be a fun project with lasting benefits for anyone interested in indoor gardening. With just a few materials, you can bring nature indoors while also creating an attractive decor element that requires minimal upkeep.
By following our DIY guide above carefully including maintenance tips like watering sparingly when necessary and occasionally pruning back overgrowth or dead leaves, you can create a self-sustaining terrarium that will thrive and grow for years to come. With a little patience and care, your terrarium can be a source of joy and inspiration.
