Decorating With Terrariums – Bring Sustainable Nature Into
Bringing the outdoors inside is a challenge every nature lover faces, especially when living in a compact RV or a minimalist homestead. You likely want a piece of the wilderness that doesn’t require a massive garden or constant watering schedules.
I promise that decorating with terrariums is the most efficient way to maintain a green thumb while living a rugged, mobile, or self-sufficient lifestyle. These miniature glass-bound worlds act as self-sustaining ecosystems that thrive with very little intervention.
In this guide, we will cover everything from selecting hardy plants to stabilizing your glass vessels for life on the road. You will learn how to design a stunning focal point that breathes life into your sanctuary without compromising your space.

Understanding the Ecosystem: Closed vs. Open Vessels
Before you start your project, you must choose the right environment for your plants. A terrarium is essentially a tiny greenhouse, but the airflow determines what can survive inside.
Closed terrariums create a self-sustaining water cycle. Moisture evaporates from the leaves and soil, condenses on the glass walls, and falls back down like rain. This setup is perfect for moisture-loving tropical plants.
Open terrariums allow for constant air circulation and lower humidity. These are ideal for desert dwellers like succulents and cacti. If you live in a damp environment, an open vessel prevents rot and fungal issues.
Consider your local climate and your indoor humidity levels. A van dweller in the Pacific Northwest might prefer an open succulent bowl to avoid excess moisture. A desert homesteader might choose a closed jar to keep plants from drying out.
Your choice of vessel also impacts your maintenance schedule. Closed systems can go months without a drop of water. Open systems require more frequent attention, though still less than a standard potted plant.
Mastering the Art of Decorating with Terrariums in Small Spaces
Living in a campervan or a tiny cabin means every square inch of counter space is valuable. Decorating with terrariums allows you to stack your greenery vertically or tuck it into unused corners.
Utilize hanging glass globes to keep your plants off the limited table surfaces. Suspending a terrarium from a sturdy hook adds visual interest at eye level and keeps the glass safe from accidental bumps.
Think about the “dead zones” in your living area, such as the space above a fridge or a high shelf. These spots often lack the light needed for large plants but are perfect for a low-light moss terrarium.
Incorporate different heights and shapes of glassware to create depth. A tall, cylindrical apothecary jar looks striking next to a round, squat fishbowl. This variety mimics the natural unevenness of a forest floor.
For those living off-grid, remember that glass reflects light. Placing a terrarium near a window can help brighten a dark cabin. Just be careful not to create a magnifying glass effect that could scorch your plants.
The Essential Layers for a Long-Lasting Terrarium
A successful terrarium is built like a layered cake. Each level serves a specific biological purpose to keep the system healthy and odor-free. Skipping a layer is the most common reason for plant failure.
Start with the drainage layer, often called the false bottom. Use pea gravel, small river stones, or expanded clay pebbles (LECA). This layer prevents water from sitting in the soil and rotting the roots.
Next, add a thin layer of activated charcoal. This is a crucial step for closed systems. The charcoal filters the water and absorbs impurities and odors that can build up in a sealed environment.
Place a physical barrier over the charcoal, such as a piece of fine plastic mesh or dried sphagnum moss. This prevents the soil from sifting down into your drainage layer and clogging it over time.
Add your substrate or potting soil. Use a high-quality mix tailored to your plant types. For tropical plants, use a peat-based or coco-coir mix. For succulents, use a gritty, sandy soil that drains rapidly.
Finally, arrange your plants and hardscape elements. Use long-handled tweezers or a chopstick to maneuver delicate roots into the soil. Firm the soil around the base of each plant to remove air pockets.
Plant Selection for Low-Maintenance Living
Not every plant is suited for life behind glass. You need species that grow slowly and tolerate the specific humidity levels of your chosen vessel. Choosing the wrong plant leads to a crowded, messy look.
For closed terrariums, Fittonia (nerve plants) are a top choice. They love high humidity and will “faint” when they need water, giving you a clear signal to check the moisture levels.
Small ferns, such as the Lemon Button Fern, add a classic woodland aesthetic. They stay relatively compact and thrive in the filtered light found in most indoor spaces.
Moss is the backbone of any forest-themed display. Use cushion moss or sheet moss to cover the soil. Moss acts as a natural carpet and helps regulate the humidity within the glass.
If you prefer an open container, look for Haworthia or Echeveria. These succulents are slow-growing and come in incredible geometric shapes. They require very little water and enjoy the airflow of an open bowl.
Avoid fast-growing ivy or large-leafed tropicals. These will quickly outgrow the container and press against the glass. This leads to leaf rot and obscures your view of the ecosystem.
Styling Your Terrarium with Natural Foraged Elements
The beauty of decorating with terrariums is the ability to tell a story. You can recreate a specific landscape you visited on your last hiking trip or scouting mission.
Incorporate “hardscape” materials like driftwood, bark, or interesting stones. These elements provide structure and make the miniature world look more realistic and aged.
If you forage for materials outdoors, you must be careful. Boil stones and bake driftwood at a low temperature to kill any hitchhiking pests or fungi that could ruin your small ecosystem.
Create focal points by using one larger “hero” stone or a gnarled piece of wood. Place smaller pebbles around the base to mimic a natural rock slide or a dry creek bed.
Consider adding tiny figurines or “found objects” for a touch of whimsy. A miniature hiker or a small ceramic tent can turn your plant display into a tribute to your outdoor lifestyle.
Leave some “negative space” in your design. Do not pack the glass full of plants. Allowing the soil or moss-covered ground to show creates a sense of scale and prevents the design from looking cluttered.
Safe Placement: Stability for Vanlife and RV Owners
For those who take their home on the road, glass containers present a safety challenge. A sudden turn or a bumpy dirt road can turn a beautiful terrarium into a dangerous mess of shards and soil.
Use museum wax or quake putty to secure the base of your terrarium to a shelf or countertop. This adhesive is strong enough to hold the glass in place during transit but can be removed without damage.
Choose heavy, thick-walled glass vessels. Thin glass is more likely to crack under the stress of temperature changes or vibrations. Opt for repurposed mason jars or heavy-duty apothecary containers.
Consider using acrylic or polycarbonate containers if you frequently travel off-road. These materials look like glass but are much more impact-resistant and lighter, which helps with your vehicle’s weight limit.
Place your terrariums in a spot where they won’t be hit by flying objects if you have to brake suddenly. Low-profile containers with a wide base are much more stable than tall, top-heavy vases.
Always check your terrarium after a long drive. Look for shifted soil or plants that may have come loose. Re-settling the roots quickly ensures the plant doesn’t suffer from stress after the journey.
Light and Temperature: Finding the Sweet Spot
Light is the fuel for your terrarium, but too much of it can be a disaster. Because the glass traps heat, placing a closed terrarium in direct sunlight can literally cook your plants.
Aim for bright, indirect light. A north-facing window is usually ideal. If you are in a van or RV, a spot near a side window with a sheer curtain provides the perfect filtered glow.
If your living space is naturally dark, use a small LED grow light. Many modern grow lights are compact and can be clipped directly onto a shelf, providing the full spectrum of light your plants need.
Monitor the temperature carefully. Most terrarium plants prefer the same temperatures humans do—between 60°F and 80°F. Avoid placing them directly in front of an AC vent or a diesel heater.
In the winter, move your glass containers away from cold windows. The glass can get extremely chilled at night, which might freeze the delicate tropical leaves inside.
Watch the condensation on the glass. A light mist in the morning is perfect. If the glass is so foggy you can’t see the plants, you have too much moisture. Open the lid for a few hours to let it vent.
Long-Term Maintenance and Troubleshooting
While decorating with terrariums is a low-effort hobby, it is not “zero effort.” A few minutes of observation once a week will keep your miniature forest thriving for years.
Prune your plants when they start touching the glass. Use long, thin scissors to snip back the growth. This encourages the plant to stay bushy and compact rather than tall and leggy.
Remove any dead or yellowing leaves immediately. In a high-humidity environment, dead plant matter will mold quickly. This mold can spread to your healthy plants and compromise the entire system.
If you see small flies, you likely have fungus gnats. These are often caused by overwatering. Let the system dry out slightly or use a tiny piece of a “mosquito dunk” in your next watering to kill the larvae.
Clean the glass inside and out. Use a damp cloth or a long-handled sponge to wipe away mineral deposits or algae buildup on the interior walls. Clear glass ensures your plants get maximum light.
Rotate your terrarium every few weeks. Plants naturally grow toward the light source. Turning the container 180 degrees ensures that your plants grow evenly and don’t lean too heavily to one side.
Frequently Asked Questions About Decorating with Terrariums
Can I use soil from my backyard for a terrarium?
It is generally not recommended. Backyard soil often contains pests, weed seeds, and fungi that thrive in a closed glass environment. Use a sterilized, store-bought potting mix to ensure your ecosystem starts healthy.
How often should I water a closed terrarium?
A well-balanced closed terrarium may only need water once or twice a year. Check the soil moisture and the condensation levels. If the soil looks dry and there is no mist on the glass, add a small amount of distilled water.
What do I do if my terrarium smells bad?
A healthy terrarium should smell like a fresh forest after rain. If it smells like rotten eggs or sulfur, you have root rot or anaerobic bacteria. This usually means the drainage layer is flooded. Open the lid and let it dry out.
Do terrariums need special water?
Using distilled water or rainwater is best. Tap water often contains chlorine and minerals that can leave white streaks on the glass and build up in the soil, potentially harming sensitive mosses and ferns.
Can I keep a terrarium in a windowless room?
No plant can survive in total darkness. If your room has no windows, you must use a dedicated grow light for at least 8 to 12 hours a day to keep the plants alive and healthy.
Cultivating Your Indoor Wilderness
Creating and decorating with terrariums is more than just a home decor trend. It is a way to maintain a vital connection to the natural world, even when you are miles away from the nearest trailhead.
For the solo traveler or the off-grid explorer, these glass gardens offer a sense of stability and peace. They remind us of the resilience of nature and the beauty of self-sustaining systems.
Start small with a single jar and experiment with different mosses and stones. As you gain confidence, you can build larger, more complex landscapes that reflect your personal journey and love for the outdoors.
Remember to prioritize the health of the plants by maintaining the proper layers and light levels. A well-cared-for terrarium is a living piece of art that will grow alongside you in your adventures.
Stay creative, stay curious, and keep bringing the spirit of the wild into your home. Happy planting!
