Terrarium decoration is a combination of art and nature that represents a self-sustaining environment living inside a glass container. However, setting up a visually appealing terrarium goes beyond merely putting together plants–it takes creativity and a deep understanding of the enclosed ecosystem. Here are some practical tips to help.
Before focusing on aesthetics, it’s essential first to consider the functionality aspects. One of the primary reasons terrariums thrive is because they mirror the natural habitat of the plants inside, therefore, consider creating a habitat that suits the type of plants you’ve chosen.
Firstly, use the correct glass structure– the shape and size of the terrarium play significant roles. Closed terrariums are suitable for tropical plants like mosses and ferns, which enjoy high humidity conditions, while open ones are ideal for succulents and cacti, which require a drier environment. Avoid overly small containers that could strain the plant’s growth. A larger terrarium promotes better air and moisture circulation, which is beneficial for the plants.
Select the right plants-– choose a selection of plants that not only look good together but share similar light, humidity, and soil conditions. Having plants with different needs in one terrarium makes its management difficult and may lead to the failure of some plants.
Bear in mind that the soil layer is crucial. A typical terrarium soil profile starts with a layer of pebbles or gravel for drainage, followed by a layer of charcoal to help filter the water and keep it fresh, then sphagnum moss to keep the soil from draining into the gravel, and lastly potting soil. The soil should be deep enough to accommodate the plant roots but also take care not to fill the container too high.
Placement of the terrarium – Determine where the terrarium will reside before choosing the plants. If the location has low light conditions, consider shade-loving plants like the nerve plant (Fittonia spp.) or ZZ plant (Zamioculcas zamiifolia). If it will be located in a brightly lit place, choose sunlight-loving plants like succulents or cacti.
Now, let’s move on to the decorative part. Creating a visually compelling terrarium decor requires a sense of balance and harmony, using both plants and non-plant elements.
Begin with a clear idea – Preplanning your terrarium’s design gives you a mental picture of what the finished creation should look like. Sketch it out; note the positioning of each plant and decorative piece. This tactic might prevent you from overcrowding the terrarium or leaving too much empty space.
Play around with the plants’ spatial arrangement – Position plants according to height; the taller ones should be at the back, and shorter ones are closer to the front, for an aesthetically pleasing layout that resembles a mini garden landscape. However, please don’t place them too close to the glass as it may cause rot due to condensation.
Incorporate gradient – Similar to natural landscapes, a textured gradient in terrain makes terrariums more visually interesting. This effect can be achieved by adjusting the soil levels, making hills and valleys, or making use of rocks and stones.
Include a focal point – A focal point draws attention and creates visual interest. It could be a larger or more colorful plant, a piece of wood or rock, or a whimsical fairy garden ornament. But remember, the star attraction shouldn’t dwarf the surrounding plants.
Use colourful pebbles and rocks – Adding some inlay materials like colorful pebbles, rocks, or patterned glass chips can lend additional color and texture to the terrarium. Be careful not to overuse them and steal the attention from the plants.
Include a personal touch – A miniature figurine, a cherished souvenir, or a collectable might add charm and personal meaning to your terrarium.
Incorporate diverse plant forms, leaf shapes, and textures, ensuring they don’t crowd each other and each plant type is clearly distinguishable.
Lastly, don’t forget the maintenance. Regularly remove dead leaves or plants to keep the terrarium looking tidy and healthy. Rotate the terrarium occasionally, especially if light comes from only one direction, to ensure equal light exposure and maintain an even growth.
A skilled terrarium decorator is both an artist and a horticulturist. While aesthetics plays a significant role, understanding the fundamental needs of the enclosed ecosystem is equally, if not more, important in creating a thriving, visually pleasing terrarium.
