Top Plants for Terrariums
Not all plants are suitable for terrariums. The best choices are those that love humidity and remain compact in size. Here are some excellent options:
1. Fittonia (Nerve Plant)
Fittonias are known for their colorful, veined leaves. They thrive in humid environments and are perfect for closed terrariums. These plants prefer low to medium light and moist soil.
2. Ferns
Small ferns like the Maidenhair or Button Fern are great for terrariums. They love humidity and indirect light. Make sure they don’t dry out completely.
3. Mosses
Moss is a favorite for lining the base of terrariums. It adds a lush, green carpet-like effect and retains moisture well.
4. Peperomia
This low-growing plant has thick, colorful leaves. It prefers indirect sunlight and does well in both open and closed terrariums.
5. Air Plants (Tillandsia)
Air plants don’t need soil and can be placed decoratively on stones or bark. They do well in open terrariums and require occasional misting.
6. Miniature Orchids
Some small orchids can thrive in humid, closed terrariums. They add elegance and a touch of color.
7. Succulents and Cacti
These are best for open terrariums, as they need good airflow and dry conditions. Overwatering or humidity can cause rot.
Open vs. Closed Terrariums
-
Open Terrariums: Best for dry-loving plants like succulents, air plants, and cacti. They allow air circulation and less humidity.
-
Closed Terrariums: Create a humid environment suitable for ferns, mosses, and tropical plants. They mimic a rainforest-like setting.
How to Set Up a Terrarium
1. Choose a Container
Pick a clear glass container with an opening wide enough to place plants inside. Fishbowls, mason jars, and geometric terrariums are popular choices.
2. Add Layers
Start with a layer of pebbles or small stones for drainage. Add activated charcoal to keep the environment fresh. Top it with potting soil suited to your plant type.
3. Plant Carefully
Arrange your plants, starting with the largest. Leave space between them for growth. Use tools like chopsticks or tweezers for better control.
4. Decorate (Optional)
Add decorative stones, moss, bark, or small figurines for aesthetic appeal.
5. Water Sparingly
Use a spray bottle or spoon to moisten the soil. Closed terrariums need less watering than open ones.
Care Tips for Terrarium Plants
-
Light: Place in bright, indirect light. Avoid direct sun, which can overheat the container.
-
Water: Water only when the soil feels dry. Closed terrariums rarely need watering.
-
Pruning: Trim plants regularly to prevent overgrowth.
-
Cleaning: Wipe glass walls and remove any dead leaves to avoid mold.

| Problem | Cause | Solution |
|---|---|---|
| Mold or mildew | Too much moisture | Open lid, reduce watering |
