Terrariums are a beautiful and versatile way to bring nature indoors, and while small, glass-encased plants are undoubtedly charming, there’s something truly awe-inspiring about a large or statement-sized terrarium. Whether displayed on a coffee table, as a centerpiece, or hanging as a suspended garden, a large terrarium can transform a space, adding a touch of nature and drama to your home decor.

Building a large terrarium is not only a creative challenge but also an opportunity to make a bold, personalized design statement. In this blog post, we’ll explore how to create large and statement terrariums, the benefits they bring to your space, and tips for assembling a breathtaking, living work of art.

Why Choose Large and Statement Terrariums?

Large terrariums offer numerous benefits beyond just being a pretty decoration. Here’s why you might want to consider adding one to your space:

  1. Bold Visual Appeal: A large terrarium makes a powerful visual impact. It serves as a stunning focal point in a room, drawing the eye and adding life to otherwise neutral or minimalist decor.

  2. Versatility: Large terrariums are incredibly versatile. You can create anything from a desert landscape with cacti to a lush tropical forest. They can suit any design style, from modern and sleek to rustic and earthy.

  3. Bringing Nature Indoors: While smaller terrariums are often placed on shelves or desks, a large terrarium can help transform a whole room by infusing it with fresh air, greenery, and a calming, natural vibe.

  4. Customization: A large terrarium gives you plenty of room to express your creativity. You can combine multiple plant species, incorporate decorative objects, or create a theme that complements the room’s design.

  5. Low-Maintenance Beauty: While larger terrariums may seem high-maintenance, once set up correctly, they are quite self-sufficient. The larger volume of air and soil means a more stable environment for plants, making them easier to maintain over time.

What You’ll Need to Build Your Large Statement Terrarium

Creating a large terrarium requires a few more materials and considerations compared to smaller versions, but with the right tools and planning, the process is simple. Here’s a breakdown of what you’ll need:

1. A Large Glass Container

The most important element in creating a statement terrarium is the container. Choose a large glass vessel that suits the space you want to decorate. Some popular options include:

  • Glass Planters: Large glass planters, such as cylindrical, square, or globe-shaped containers, are commonly used for terrariums. They allow plenty of space for plant growth and are visually striking.

  • Aquarium Tanks: For an even larger scale, glass aquarium tanks work well as terrarium containers. They offer ample room for larger plant species and create a beautiful, natural atmosphere.

  • Hanging Glass Globes: For a unique twist, you can use large, suspended glass globes or hanging terrariums to create a floating, garden-in-the-sky effect.

2. Substrate Materials

To create a balanced environment for the plants in your large terrarium, you'll need the following layers of substrate:

  • Gravel or Pebbles: This provides drainage at the bottom of the container to prevent water from collecting and causing root rot.

  • Activated Charcoal: A thin layer of activated charcoal helps to keep the air fresh inside the terrarium by preventing odor buildup and filtering impurities.

  • Sphagnum Moss: A layer of moss keeps the soil from mixing with the drainage material while also maintaining moisture.

  • Potting Soil: Choose a well-draining potting mix that suits the plants you’re working with. For succulents, go for a cactus or succulent mix. For tropical plants, a moisture-retentive mix will work best.

3. Plants

The selection of plants will make or break the success of your terrarium. When choosing plants for a large terrarium, consider their light and moisture needs. Here are a few options depending on the type of environment you want to create:

  • Tropical Plants: If you’re aiming for a lush, rainforest vibe, plants like Ferns, Fittonia (nerve plant), Pilea, and Bromeliads are excellent choices.

  • Succulents and Cacti: For a more desert-like atmosphere, incorporate plants such as Echeveria, Aloe Vera, Cactus, and Sedum.

  • Moss: Adding moss will give your terrarium an earthy feel and enhance the look of the ecosystem. Sheet moss or cushion moss works well for large terrariums.

  • Air Plants: These unique plants can be placed anywhere inside your large terrarium, as they don’t require soil. Tillandsia varieties are great for adding texture and interest.

4. Decorative Elements

Decorative items bring personality and charm to your large terrarium. Some ideas include:

  • Rocks and Stones: Add texture, color, and contrast to the greenery with smooth river rocks, pebbles, or even larger stones.

  • Driftwood: A beautiful piece of driftwood can serve as a focal point and add height to your design.

  • Miniature Figurines: Bring whimsy to your terrarium with tiny figurines, such as fairies, animals, or houses.

  • Fairy Lights: For a magical, glowing effect, string some battery-operated fairy lights around the plants or along the walls of the container.

5. Tools

Since you'll be working with a large container, having the right tools will make the process easier:

  • Gardening Trowel: For adding and arranging soil.

  • Tweezers or Long-Handled Tools: To plant and position smaller plants without disturbing the substrate.

  • Watering Can or Spray Bottle: For lightly misting your plants, especially when dealing with delicate tropical species.

  • Gloves: If you want to keep your hands clean while working with the soil and plants, a pair of gloves will come in handy.

How to Build Your Large Statement Terrarium

Building a large terrarium is similar to assembling a smaller one, with a few extra considerations. Here’s a step-by-step guide:

1. Prepare the Container

Start by cleaning your large glass container thoroughly. Dust and dirt will interfere with your view of the plants, so make sure it's spotless before you begin.

2. Create the Drainage Layer

Place a 2-inch layer of gravel or pebbles at the bottom of the container. This allows water to drain and prevents root rot by keeping the plants' roots from sitting in excess moisture.

3. Add Activated Charcoal

Sprinkle a thin layer of activated charcoal on top of the gravel. This helps with odor control and ensures the ecosystem remains fresh.

4. Layer the Moss

Add a layer of sphagnum moss to keep the soil separate from the charcoal and prevent it from mixing with the drainage layer. The moss also adds a natural touch to the terrarium.

5. Add the Potting Soil

Now, add your potting soil. The amount will depend on the height of your container, but a 3-4 inch layer should work for most large terrariums. Smooth the soil so it’s even and level.

6. Arrange Your Plants

Carefully arrange your plants inside the container. Start by placing larger plants at the back or center and smaller plants toward the front. Be sure to leave enough space between them for growth. Use tweezers or a small tool to position each plant.

7. Add Decorative Elements

Now comes the fun part—adding decorations! Place your rocks, driftwood, or figurines, and add any final touches. Be mindful of the balance in the ecosystem and avoid overcrowding the terrarium.

8. Water and Seal

Lightly water your terrarium with a spray bottle or watering can, ensuring the soil is moist but not soggy. Seal the container with the lid or cover to create a closed environment. If you're using a container without a lid, be sure to monitor moisture levels and adjust the watering as needed.

9. Place in the Right Spot

Place your large terrarium in an area with bright, indirect light. Avoid direct sunlight, as it can cause the container to overheat and damage the plants.

Maintaining Your Large Terrarium

Once your large statement terrarium is set up, it’s relatively easy to maintain:

  • Watering: Check the moisture levels in the soil. If the soil seems dry, lightly mist or water the plants. Be cautious not to overwater, as the sealed environment helps maintain humidity.

  • Light: Make sure your terrarium gets enough light, but not too much direct sunlight. If the plants appear to be stretching toward the light, consider rotating the container.

  • Pruning: Over time, plants may grow too large. Trim back any leggy or overgrown plants to keep your terrarium looking neat and healthy.

Conclusion

Building a large, statement terrarium is a creative and rewarding way to bring a touch of nature into your home. With the right container, plants, and decorative elements, you can design a stunning piece of living art that not only enhances your space but also brings tranquility and beauty. Whether you choose a tropical paradise, a desert oasis, or a simple moss garden, a large terrarium can make a bold statement and become a centerpiece of your home decor. So, gather your materials, unleash your creativity, and get ready to build a unique terrarium that will impress both you and your guests for years to come.
