Understanding the balance of light, moisture, and space is imperative when curating a terrarium. Certain plants require a high humidity and thrive under indirect light, making them perfect candidates for an enclosed terrarium. For example, ferns like the maidenhair or the bird’s nest provide an elegant texture and flourish in such conditions. On the contrary, plants that prefer a more arid environment, such as air plants, may be better suited for open terrariums where airflow can prevent rot.
Maintaining a terrarium also involves the delicate art of landscaping within a limited space to create an aesthetically pleasing and balanced display. It is vital to select plants that not only support the climate of the terrarium but also contribute to the desired visual appeal. Plants should be sized and arranged in a way that allows for growth and brings a piece of the natural world into the enclosed glass space, providing enjoyment and a sense of tranquility to the observer.
Essentials of Terrarium Design
Creating an alluring terrarium oasis hinges on understanding the types of terrarium environments, selecting an appropriate container, and carefully constructing the internal layers with the right soil and conditions that plants require to thrive.
Understanding Terrarium Types
Terrariums are primarily categorized as closed terrariums, which are usually sealed to create a humid environment, and open terrariums, which allow for greater airflow and are suitable for plants preferring drier conditions. The choice between the two significantly dictates the subsequent design and care requirements.
Selecting a Suitable Container
The terrarium container should reflect the specific needs of your chosen plants. Glass containers are popular, with options ranging from a simple glass bowl to more complex designs. The transparency of glass allows for easy enjoyment of the greenery within while also facilitating the penetration of indirect light.
Creating a Foundation
A proper foundation is vital and begins with a drainage layer made of pebbles or rocks, followed by a thin layer of charcoal to keep the water fresh and prevent mold. This base ensures excess water can settle without causing root rot, crucial for a healthy terrarium.
Choosing the Appropriate Soil
The soil in your terrarium should be tailored to the plants you wish to grow. Adding perlite can improve drainage, which is especially important in a closed system. Some plants may require sandier soil, while others do better with a peat-based mix, so it’s essential to match the soil composition to the plants’ natural habitats.
Light and Temperature Considerations
Terrariums thrive in indirect light; direct sunlight can be too intense, causing a greenhouse effect that can harm the plants. Ideal temperature conditions mimic a moderate climate, avoiding extremes that could stress the plants or disrupt the terrarium’s balance.
Humidity and Airflow Management
In a closed terrarium, the humidity level will naturally rise, creating a humid environment. Open terrariums require careful watering to maintain moisture without creating stagnation. Regardless of type, managing airflow by occasionally opening the terrarium can prevent mold and promote a healthy ecosystem.
Plant Selection and Care
Selecting the right plants for your terrarium is crucial for its success and requires understanding the specific care each type needs. Whether your terrarium is closed, fostering a high-humidity environment, or open, accommodating dry-loving plants, proper watering, feeding, and maintenance will ensure a thriving miniature ecosystem.
Best Plants for Closed Terrariums
Closed terrariums excel at maintaining high humidity and are ideal for tropical plants and mosses. They replicate a rainforest-like atmosphere. Ferns, like the maidenhair and bird’s nest varieties, are recommended for closed terrariums due to their need for constant moisture and indirect light. Mosses, such as pillow moss and sheet moss, also thrive in these conditions as they require a stable moist environment.
- Ferns: Maidenhair (Adiantum spp.), Bird’s Nest (Asplenium spp.)
- Mosses: Pillow Moss, Sheet Moss

Top Plants for Open Terrariums
Open terrariums, on the other hand, are well-suited for plants that prefer drier conditions, like succulents, cacti, and air plants. These plants require good air flow and less frequent watering, making them perfect for an open environment. Examples include:
- Succulents: Echeveria, Haworthia
- Cacti: Star Cactus (Astrophytum asterias), Pincushion Cactus (Mammillaria)
- Air Plants: Tillandsia spp.
These selections are adapted to the low-humidity atmosphere found in The Best Plants for Open Terrariums.
Watering and Feeding
Adequate watering of terrarium plants varies significantly between closed and open environments. Closed terrariums often need watering only once a month, as they recycle moisture already present in the ecosystem. Open terrariums may require a more regular watering schedule depending on the dryness of the surrounding air. For both types, overwatering can lead to root rot and should be avoided. Feeding is minimal: a diluted liquid fertilizer can be applied sparingly during the growing season.
Pruning and Maintenance
Regular maintenance, including pruning, helps to maintain the health and appearance of terrarium plants. Remove dead or dying foliage to prevent the spread of diseases and to allow for new growth. Pruning also helps control the size of the plants, ensuring they don’t outgrow their glass home. Pay attention to signs of stress in plants, such as discoloration or wilting, which may indicate issues with watering or light levels.
By adhering to these care tips and choosing appropriate plants, one can buy terrarium plants with confidence. A well-maintained terrarium is a beautiful, self-sustaining display that brings the essence of nature indoors.
Creating Your Terrarium Oasis

Creating a terrarium oasis involves careful layering and planting of various plants to mimic a miniature ecosystem. It requires not only an eye for aesthetics but also an understanding of the living conditions each plant needs to thrive. Here are specific techniques to ensure a healthy and visually appealing terrarium.
Layering and Planting Techniques
A terrarium functions as a self-sustaining greenhouse. Begin by adding a layer of rocks at the base for drainage, followed by a layer of charcoal to keep the environment fresh and reduce the risk of mold. Then, add a layer of potting soil designed for terrariums.
- Rocks: 1-2 inches depending on container size.
- Charcoal: Half an inch above the rocks.
- Soil: Enough to allow plants’ roots to spread without crowding.
For planting, choose adaptable and lush plants like succulents or ferns. Make small wells in the soil for each plant, ensuring roots are well-covered but not compacted, to prevent root rot.
Arranging Plants Aesthetically
Carefully consider terrarium plant ideas that complement each other in textures and colors. Place taller plants in the back and shorter ones in front to maintain visibility and create depth.
- Contrast plant features: Pair fine-textured ferns with broad-leafed succulents.
- Color variety: Use varying green shades or add pops of color with flowering species.
Incorporate elements such as small figurines or stones to create focal points within your terrarium to guide the eye and add extra character.
Long-term Terrarium Health
To maintain a terrarium, one must balance light, water, and air flow. Here are keys to ensure long-term health:
- Light: Provide indirect sunlight; direct sun can cause overheating.
- Water: Mist plants sparingly; overwatering is a common pitfall.
- Airflow: Open terrariums occasionally to let in fresh air and remove excess moisture.
Monitor your plants for signs of stress and adjust care as necessary. Pruning overgrown plants will help maintain a neat appearance and support continued growth. Regular inspection for pests and decay is crucial for a thriving terrarium oasis.
