5 Creative Terrariums to Try This Long Weekend A long weekend offers the perfect opportunity to pause, reset, and engage in a creative, low-stress project that brings a piece of the outdoors inside. Terrariums, which are miniature, self-sustaining ecosystems in glass containers, are ideal projects for bringing nature into small spaces. They are relatively easy to maintain, reducing the need for constant attention. They provide a unique blend of artistry and botany. Whether one is an experienced horticulturist or a beginner with a love for DIY, creating these vibrant, mini worlds can be relaxing. Here are five unique terrarium styles to build over a long weekend.
1. The Classic Closed Tropical TerrariumThe closed terrarium is the ultimate self-sustaining environment, creating a tiny, humid paradise. To start, select a glass vessel with a tight-fitting lid—a vintage apothecary jar or a sturdy cookie jar works beautifully. The process begins with a drainage layer, such as gravel or leca (lightweight expanded clay aggregate), followed by activated carbon to prevent bacterial growth and odor. After adding a specialized tropical potting mix, one can plant small ferns, nerve plants (Fittonia), or polka dot plants. Once sealed, the water cycle inside becomes a closed loop, rarely needing to be watered, making it an excellent long-term decoration. The ideal environment for a terrarium is a cool spot, with temperatures between 18 and 23 degrees Celsius, to prevent excessive heat from causing the plants to rot.
2. The Desert Dry LandscapeFor those who prefer a low-maintenance, arid-themed display, a desert-themed open terrarium is perfect. Because succulents and cacti thrive on dry air and high light, an open container—like a geometric glass bowl or a wide-mouthed fishbowl—is essential, as it allows for proper airflow. Begin with a deep base of sandy soil mixed with gravel to ensure rapid water drainage. Arrange small cacti, echeverias, or sedum, and decorate the surface with decorative gravel, sand, or interesting pieces of driftwood to create a tiny desert vista. These ecosystems thrive in sunny spots but require very little water, allowing for a truly “set it and forget it” green display.
3. The MossariumA “mossarium” is a specialized type of terrarium that focuses entirely on the lush, vibrant textures of various moss species. Often housed in a sleek, polygonal glass container, a mossarium is designed to showcase the beauty of cushion moss, sheet moss, or fern moss, which flourish in high-humidity, enclosed spaces. These setups are particularly soothing, evoking the feeling of a quiet, enchanted forest floor. To build one, it is important to lay down a thin, consistent layer of substrate and use damp, clean moss. A closed container is necessary to maintain the constant moisture levels that moss requires, and a few small branches or stones can be added to provide a beautiful, natural contrast.
4. The Miniature Woodland SceneThis project is all about creating a tiny, whimsical landscape, reminiscent of a miniature fairytale forest. Using a large, wide-mouthed glass jar, build a base of soil and add small, shade-loving plants like miniature ivy or creeping fig. The key here is the “scaping,” where tiny accessories can be introduced, such as small pebbles for a miniature path, a tiny wooden bridge, or even small figurines. This style is excellent for those looking to add a personal, imaginative touch to their home decor. Moss can also be used as a ground cover, blending the different elements of the landscape together.
5. The Upcycled Jar TerrariumThis approach focuses on sustainability, using old jars—such as jam jars, mason jars, or pickle jars—that might otherwise be destined for the recycling bin. The limited space makes this a quick, rewarding project that can be completed in just a few hours. Because of the restricted space, small-scale plants like mosses, baby tears, or small, slow-growing ferns are ideal. These small, decorative, and eco-friendly pieces make perfect gifts or thoughtful additions to desks and bookshelves. It is a fantastic way to practice the principles of terrarium building without needing expensive, large containers, allowing for experimentation and multiple, distinct mini-ecosystems to be created over the course of a weekend.
A Note on CareTo ensure a long-lasting, healthy ecosystem, it is vital to keep the terrarium out of direct sunlight, which can overheat the glass and damage the plants. If using tap water, it is best to let it sit for a day to allow chemicals like chlorine to dissipate, ensuring a healthier environment for the plant roots. Signs of overwatering in closed terrariums include blackening leaves, mold build-up, and plants turning to mush. By adding small helpers like springtails, one can maintain a healthy, clean, and thriving ecosystem that manages its own decaying organic matter.
Creating these five types of terrariums offers a wonderful opportunity to connect with nature, even from the comfort of home. Each design provides a unique, living piece of art that brings life and color into any room. By dedicating a bit of time over a long weekend, one can build a thriving, low-maintenance ecosystem that will continue to grow and evolve for months or even years to come.
