Terrariums are fascinating. They act as their own little ecosystem, which you can (quite literally) bottle up and keep in your house. We love the creativity and calming energy that these miniature gardens provide. Whether you’re a beginner looking to create your first terrarium or an experienced micro-gardener eager to refine your technique, this guide will walk you through the process of building a thriving terrarium that reflects your personal style.
The foundation of every great terrarium is the container. For those new to terrarium building, starting with a clear glass container is ideal—it allows you to observe the inner workings of your little ecosystem. Containers can range from classic glass jars and bowls to more creative options like vintage aquariums or geometric vessels. For experts, consider experimenting with unique shapes or even custom-built terrarium structures to elevate your design. Your container can be open or closed - open containers tend to work best for succulents and air plants, while closed containers are great for humidity-loving tropicals.
Along with your container, you’ll need a few essential materials:
For both newbies and seasoned terrarium enthusiasts, gathering quality materials is key. Investing in good supplies not only makes the process more enjoyable but also sets the stage for a long-lasting, healthy terrarium.
One of the most exciting parts of building a terrarium is choosing the right plants. If you’re just starting out, opt for hardy, low-maintenance species that tolerate a closed environment well. Make sure the plants you select all have similar moisture and light needs. Many beginners find that ferns and mosses are excellent choices due to their forgiving nature and lush appearance. Experts might experiment with a mix of textures and colors, incorporating a variety of species to create visual contrast and depth. We have “pixie plants” at our garden centers that are perfect, miniature plants to use in your terrarium.
Some of our favorites include:
When planning your layout, consider the height, color, and growth habits of each plant. Arrange taller plants toward the back or center (depending on your container’s shape) and layer smaller ones in front. This tiered approach not only looks appealing but also ensures that each plant gets enough light. For a harmonious design, leave a bit of space between plants to allow them room to grow—especially important in a confined terrarium.
Remember, a terrarium is a miniature ecosystem. For those with experience, balancing aesthetics with the practical needs of the plants can be a rewarding challenge. Experiment with different arrangements, and don’t be afraid to make changes along the way. Even if you’re an expert, sometimes the best ideas come from a little trial and error.
Now that you’ve chosen your container and plants, it’s time to assemble your terrarium—a process that’s both an art and a science. Begin by layering your materials in your container. Start with the drainage layer of stones or gravel - this will help prevent root rot which is caused when plant roots sit in water consistently. Then, add a thin layer of activated charcoal to keep the water fresh; you don’t need much. Next, place a layer of sand to aid in water retention. Follow-up with your substrate, giving your plants plenty of space to establish roots, while also leaving enough room in the container for your plants and decorative touches.
The essential layers include:
For both beginners and advanced gardeners, the key here is to work slowly and thoughtfully. Arrange your plants carefully, making sure to create a balanced composition. Use tweezers or small gardening tools to adjust delicate plants, and consider the final look as you layer each element. (Some of us even like to use chopsticks!) As you place each plant, lightly press the soil around the roots to ensure a snug fit.
Finally, add your decorative elements. This is your chance to inject personality into your terrarium—use colorful pebbles, a bit of decorative moss, or even small ornaments that tell a story. The process should be as enjoyable as the final product. With every layer you add, you’re not just building a terrarium; you’re crafting a living piece of art.
Find the perfect spot in your house for your new masterpiece. Keep in mind the lighting needs of the plants you selected, and place your terrarium accordingly. You’ll also want to water-in all of your plants to get them started. This isn’t a drenching, just a misting until you see water trickling down into your soil layer. Terrariums are great at retaining moisture, so you won’t need to water nearly as often as you do traditionally-potted plants. Closed terrariums can survive weeks or months without any maintenance. Just sit back and enjoy your beautiful creation!
