Learn how to create and maintain a thriving succulent terrarium
A succulent terrarium offers a delightful way to display the unique beauty of succulents in a controlled, miniature environment. These low-maintenance terrariums not only add a touch of greenery to your space but also serve as a great project for both beginners and experienced gardeners.
Here’s everything you need to know to create and maintain a thriving succulent terrarium.
Select a container that complements your style—glass bowls, jars, and even unique geometric terrariums work well. Opt for containers with wide openings to ensure good air circulation, which is crucial for succulents.
The first layer in your terrarium should be rocks or gravel. This layer acts as a false drainage system, allowing excess water to settle away from the plant’s roots. Pour a layer about one to two inches thick, depending on the size of your container. This not only aids in drainage but also adds a visual element to the terrarium.
Just above the gravel, add a thin layer of activated charcoal. This layer is not mandatory, but it’s highly recommended, especially in sealed containers. Activated charcoal helps to remove toxins and odors from the soil and water, keeping the terrarium environment fresh and reducing the growth of mold and bacteria.
Place a layer of sphagnum moss over the charcoal to act as a barrier between the gravel and the soil. This prevents the soil from trickling down into the gravel while still allowing water to drain through. This layer keeps the soil layer stable and prevents it from becoming compacted.
The final layer before adding your plants is the succulent soil mix. Use a pre-mixed succulent or cactus soil, or make your own by combining potting soil with sand and perlite in equal parts for improved drainage. This layer should be deep enough to support the roots of your plants.
Choose succulents that vary in color, texture, and height to create visual interest. Ensure they have similar light and water needs. It’s best to use succulents that are small and slow-growing to prevent overcrowding.
Arrange your succulents by removing them from their pots and gently teasing apart the roots. Plant them in the soil, making sure they’re spread out evenly. Leave some space between the plants to allow for air circulation and growth.
After planting, you can add decorative rocks, moss, or even miniature figures to enhance the aesthetic of your terrarium.
Place the terrarium in a location that receives indirect, bright light. Avoid direct sunlight as it can magnify through the glass and burn the plants.
Creating a succulent terrarium is not only an enjoyable DIY project but also an excellent way to bring a piece of nature into your home. With minimal care, these terrariums can provide lasting beauty.
Caring for a succulent terrarium is relatively easy, but it does require some attention to ensure the plants thrive in their enclosed environment. Here’s a guide to help you maintain a healthy and beautiful succulent terrarium:
Succulents need plenty of bright, indirect light. Place your terrarium near a window that receives ample sunlight but avoid direct exposure which can lead to overheating and sunburn for the plants, especially through glass.
Overwatering is the most common issue in succulent care, especially in terrariums with limited drainage. Water your succulents sparingly—typically every 2-4 weeks, depending on the climate and environment. Use a spray bottle or a small watering can to gently water the base of the plants, ensuring the soil is lightly moistened but not soggy.
Good airflow is crucial to prevent moisture buildup that can lead to mold and rot. If your terrarium is sealed, open it occasionally to let air circulate, especially if you notice condensation on the glass.
Keep the glass clean to ensure maximum light penetration. Wipe the inside with a dry or slightly damp cloth to remove dust and clear condensation that can block sunlight.
Remove dead or dying leaves to keep the terrarium looking tidy and to prevent decay, which can spread to healthy parts of the plant. Pruning also encourages growth and maintains the plants’ compact shapes.
Succulents require minimal feeding. If desired, you can apply a diluted, balanced, liquid fertilizer once a year during the growing season to promote growth. Be cautious with the amount; a little goes a long way.
Check regularly for signs of pests such as aphids, mealybugs, or spider mites. If you spot pests, treat the plants with a gentle insecticide or remove them manually using a cotton swab dipped in alcohol.
Watch for signs of stress, such as discoloration or dropping leaves, which could indicate improper lighting or watering issues. Adjust care practices as needed based on the condition of your plants.
Succulent terrariums can last indefinitely with proper care. The longevity largely depends on the environment you provide, including appropriate lighting, watering, and maintenance. Succulents are slow-growing and can thrive in a confined space for years.
Yes, succulents in a terrarium do require watering, but much less frequently than those in open containers. Because terrariums often lack drainage, water sparingly to avoid waterlogging, which can lead to root rot. Typically, watering once every 2-4 weeks is sufficient, depending on the humidity and light conditions. Always check the top inch of the soil; if it feels dry, it’s time to water.
