Creating Your Glass Cloche Terrarium

When it comes to creating a beautiful glass cloche terrarium, there are several important factors to consider. From selecting the right glass cloche to preparing the base layer and choosing and arranging the plants, each step plays a vital role in ensuring the success of your terrarium. In this article, we will guide you through each of these steps in detail, providing you with all the information you need to create a stunning glass cloche terrarium.

Selecting the Right Glass Cloche

The first step in creating a glass cloche terrarium is selecting the appropriate size and shape of the glass cloche. This is crucial to ensure that your terrarium is both aesthetically pleasing and functional. Consider the following factors when choosing your glass cloche:


The dimensions of the glass cloche will determine the amount of space available for your plants and other decorative elements. A larger glass cloche will allow for more plants and a greater variety of plant species. However, it is important to consider the available space in your home and select a size that fits well within your surroundings.


Glass cloches are typically made from either glass or plastic. While both materials can be used successfully, glass cloches offer several advantages. They provide better visibility, allowing you to enjoy the beauty of your terrarium from all angles. Glass also retains heat more effectively than plastic, creating a more suitable environment for the plants inside.


The design of the glass cloche is another important consideration. Some cloches have a more traditional shape, resembling a bell or dome, while others may have unique or intricate designs. Choose a design that complements your personal style and the overall aesthetic you wish to achieve with your terrarium.

Preparing the Base Layer

The base layer of your glass cloche terrarium serves two essential purposes. Firstly, it acts as a drainage system, ensuring that excess water can flow out of the terrarium to prevent root rot. Secondly, it helps maintain proper moisture levels within the terrarium.

To prepare the base layer, start by selecting suitable materials such as rocks or activated charcoal. These materials should be clean and free from any chemicals or toxins that could harm your plants. Arrange the chosen materials in a layer at the bottom of the terrarium, ensuring even coverage.

If using rocks, select a variety of sizes to create a textured and visually appealing base layer. The rocks will allow excess water to drain freely through the gaps, preventing water from pooling around the roots of your plants.

If using activated charcoal, spread a layer evenly across the bottom of the terrarium. Activated charcoal helps to filter out any impurities in the water, keeping it clean and fresh for your plants.

Choosing and Arranging Plants

The selection and arrangement of plants are key factors in creating a visually stunning glass cloche terrarium. It is important to choose plants that thrive in the specific conditions provided by a closed terrarium, such as high humidity and limited airflow.

When selecting plants, consider their mature size and growth habit. Choose plants that will stay small or have a slow growth rate to ensure they do not outgrow the terrarium. Some suitable plant options include ferns, mosses, succulents, and air plants.

Before planting, carefully plan the arrangement of your plants. Consider their complementary colors, textures, and growth patterns. Start by placing taller plants towards the back of the terrarium and smaller plants towards the front. Create depth and visual interest by varying the height and density of the plants.

When arranging the plants, gently loosen the root ball and place them in the base layer. Position the plants securely and add additional soil or moss around the roots to provide stability.

After planting, mist the terrarium with water to create a humid environment. Be cautious not to overwater, as excessive moisture can lead to the growth of mold or other plant health issues.

With the right glass cloche, a well-prepared base layer, and carefully selected and arranged plants, you can create a stunning glass cloche terrarium that will be a beautiful addition to any space in your home. Enjoy the process of creating and caring for your terrarium, and watch as it transforms into a captivating miniature world of greenery and beauty.

Caring for Your Glass Cloche Terrarium

Providing the Right Amount of Light

Proper lighting is essential for the health of the plants in your glass cloche terrarium. The amount of light required depends on the specific types of plants you have chosen to grow inside your terrarium.

If you have selected plants that thrive in direct sunlight, such as succulents or cacti, it is crucial to place your glass cloche terrarium in a spot where it receives bright, indirect sunlight for several hours each day. Windowsills or areas near south-facing windows are excellent locations for these light-loving plants.

On the other hand, if your terrarium contains ferns or other shade-loving plants, it is best to position it in an area with filtered or indirect sunlight. Placing it near an east or north-facing window will provide the right amount of light without exposing the plants to harsh direct sunlight, which can burn their leaves.

During the summer months, when the sun’s rays are particularly strong, it may be necessary to provide some shade for your terrarium. You can use sheer curtains or blinds to diffuse the sunlight or move it to a slightly shadier area to protect the delicate plants from potential sunburn.

Remember to rotate your glass cloche terrarium regularly to ensure that all sides of the plants receive equal amounts of light. This will encourage balanced growth and prevent the plants from leaning towards the light source.

Maintaining the Moisture Levels

Maintaining the right moisture levels is vital to prevent the plants from drying out or becoming waterlogged inside your glass cloche terrarium. Proper watering techniques and regular monitoring are key to achieving the optimal moisture balance.

Unlike traditional potted plants, terrariums create a self-contained environment that recycles moisture. This means you will not need to water them as frequently as regular plants. Overwatering can lead to root rot, while under watering can cause dehydration.

To water your terrarium, it is advisable to use a small watering can with a narrow spout or a spray bottle. This allows you to direct the water precisely to the soil rather than soaking the plants’ leaves. Pour water slowly and carefully to avoid causing any disturbance to the miniature landscaping inside.

Before watering, always check the moisture level of the soil. Insert your finger about an inch into the soil to test its dampness. If it feels dry, it is time to water your terrarium. If it feels moist, it is best to wait a few more days before watering. Remember, it is safer to underwater a terrarium than to overwater it.

Another essential factor in maintaining proper moisture levels is ventilation. It is crucial to remove the glass cloche periodically to allow fresh air to circulate within the terrarium. This also helps to prevent excessive moisture build-up, which can lead to fungal growth or other plant diseases.

Additionally, if you notice excess condensation on the glass walls, it is a sign that your terrarium is too humid. In such cases, remove the glass cloche for a few hours to allow the excess moisture to evaporate. However, if you consistently struggle with excess condensation, it may be necessary to adjust the planting mix or reduce the frequency of watering.

Pruning and Cleaning

Regular pruning and cleaning not only help keep your glass cloche terrarium aesthetically pleasing but also contribute to the overall health of the enclosed plants. Over time, plants may outgrow their allocated space or develop dead leaves, making pruning an important maintenance task.

When pruning your terrarium plants, use clean and sharp scissors or pruning shears to ensure a precise and clean cut. Remove any yellowed or decaying leaves, as well as any branches or stems that have grown too long or are overcrowding the space. By doing so, you prevent the plants from competing for nutrients and sunlight, promoting a healthier growth pattern.

Cleaning your glass cloche terrarium involves removing dust and debris that may have settled on the plants, decorations, or the glass itself. This not only keeps your terrarium looking beautiful but also allows the maximum amount of light to reach the plants and ensures better air circulation.

To clean the inside of your terrarium, use a soft-bristled paintbrush or a feather duster to gently brush off any dust or debris. If there are hard-to-reach spots or stubborn dirt, you can use a cotton swab or a soft cloth slightly dampened with water. Avoid using any chemicals or cleaning products, as they can be harmful to the plants.

For the exterior glass, you can use a cloth dampened with a glass cleaner or a mixture of equal parts water and vinegar to remove fingerprints or smudges. Wipe it gently to avoid scratching the glass surface.

By regularly tending to the pruning and cleaning needs of your glass cloche terrarium, you ensure that it remains a beautiful and healthy home for your miniature plant ecosystem.

Troubleshooting Common Issues

Dealing with Excessive Condensation

Excessive condensation can pose a threat to the health and vitality of the plants residing within your glass cloche terrarium. If left unaddressed, it can lead to root rot, mold growth, and other detrimental consequences. Understanding the causes behind excessive condensation and implementing effective solutions is crucial.

The primary factor contributing to excessive condensation is high humidity within the terrarium. While some condensation is normal and even beneficial for the plants, an excess can indicate an imbalance in the environment. One possible cause may be overwatering. If you notice an abundance of condensation, try reducing the frequency and amount of water you provide to the terrarium. Allow the soil to dry out slightly between waterings to help maintain a healthier moisture level.

In addition to overwatering, inadequate airflow can also cause excessive condensation. Ensure that your terrarium has good ventilation to allow for proper air circulation. Consider removing the glass cloche for a short period each day to let fresh air in and excess moisture escape. This simple practice can go a long way in mitigating condensation-related issues.

If adjusting watering and improving ventilation does not resolve the problem, you may need to reconsider the placement of your glass cloche terrarium. Avoid exposing it to direct sunlight or placing it near heat sources, as excessive heat can further contribute to condensation. Finding a suitable location with consistent, indirect light will help create a healthier environment for your plants.

Preventing Mold and Fungal Growth

Mold and fungal growth can be a common issue in glass cloche terrariums if the conditions are not properly balanced. While these organisms are a natural part of the ecosystem, an overgrowth can harm your plants and negatively impact the overall aesthetics of the terrarium. Taking preventive measures and addressing mold and fungal issues promptly is essential for maintaining a thriving terrarium.

One effective way to prevent mold and fungal growth is to carefully select the plants for your terrarium. Opt for plants that are better suited to the enclosed environment, such as those that thrive in high humidity and low-light conditions. Researching and choosing plants with natural resistance to mold and fungal diseases can significantly reduce the risk.

Proper ventilation is another crucial factor in preventing mold and fungal growth. Good airflow helps keep the environment dry and discourages the proliferation of these organisms. As mentioned earlier, removing the glass cloche for short periods and ensuring adequate air circulation will help create an inhospitable environment for mold and fungus.

In addition to plant selection and ventilation, monitoring moisture levels is vital. Avoid overwatering your terrarium, as excess moisture provides a conducive environment for mold and fungal growth. Instead, adopt a regular watering schedule and allow the soil to dry out moderately between waterings. Consider using a spray bottle to lightly mist the plants rather than pouring water directly onto the soil, as this can help control moisture levels more effectively.

If you do notice the presence of mold or fungus in your glass cloche terrarium, swift action is necessary. Carefully remove the affected plant or area and isolate it from the rest of the terrarium to prevent further contamination. Wipe down the glass cloche and surrounding surfaces with a mild vinegar solution to eliminate any remaining spores. Adjust watering habits and improve ventilation to create a less favorable environment for mold and fungus to thrive.

The first step in reviving dying plants is to assess their health and determine the specific issues they are facing. Common problems include inadequate sunlight, over or under-watering, nutrient deficiencies, or pest infestations. Once you have identified the root cause, you can take appropriate steps to address the problem.

If your plants are not receiving enough sunlight, consider relocating the terrarium to a spot with brighter, indirect light. On the other hand, if they are exposed to excessive sunlight, move the terrarium to a shadier location to prevent scorching and wilting.

Watering issues are often the primary cause of plant decline. Ensure you are providing an adequate amount of water based on the specific needs of the plants within your terrarium. Check if the soil is consistently moist but not waterlogged. Adjust your watering frequency and method accordingly to provide the optimal level of hydration.

Nutrient deficiencies can also contribute to plant deterioration. Consider using a balanced liquid fertilizer specifically formulated for terrarium plants. Follow the package instructions carefully to avoid over-fertilization, which can have adverse effects.

If you suspect a pest infestation, closely inspect your plants for signs of insects or other pests. Common indicators include yellowing leaves, holes in the foliage, or small bugs crawling on the plants. Treat the infestation promptly using organic insecticides or other appropriate methods to eliminate the pests and prevent further damage.

In cases where the plant’s decline is irreversible, it may be necessary to remove and replace it. Transplanting a healthier replacement plant into the terrarium will help maintain the balance and vitality of the ecosystem.

Remember that caring for plants in a glass cloche terrarium requires patience and observation. Regularly monitor the condition of your plants, make adjustments as needed, and provide the necessary care to ensure their well-being.
