Terrariums are miniature gardens enclosed in glass containers, creating a beautiful self-sustaining ecosystem perfect for any space.
Types of Terrariums
Closed Terrariums
Sealed environments that recycle water through condensation. Best for moisture-loving plants like ferns, moss, and fittonias.
Open Terrariums
Have an opening for air circulation. Ideal for succulents, cacti, and air plants that prefer drier conditions.
Materials Needed
- Glass container (jar, bowl, or specialized terrarium)
- Pebbles or gravel for drainage
- Activated charcoal to prevent odors and bacteria
- Potting soil appropriate for your plants
- Small plants suited to your terrarium type
- Decorative elements (optional): stones, figurines, driftwood
Step-by-Step Assembly
1. Create Drainage Layer
Add 1-2 inches of pebbles at the bottom for drainage and to prevent root rot.
2. Add Charcoal
Spread a thin layer of activated charcoal over the pebbles. This keeps the terrarium fresh.
3. Add Soil
Pour in potting mix, creating hills and valleys for visual interest. Depth depends on plant root size.
4. Plant Selection and Placement
Choose plants with similar light and water needs. Create depth by placing taller plants in back, shorter ones in front.
5. Decorate
Add decorative elements carefully without overcrowding. Leave space for plants to grow.
Terrarium Care
Closed Terrariums
Water sparingly - only when condensation stops forming. Open lid occasionally if too much moisture accumulates. Provide indirect light.
Open Terrariums
Water when soil is dry, typically every 1-2 weeks for succulents. Ensure adequate airflow and bright indirect light.
Troubleshooting
- Too much condensation: Open lid for ventilation
- No condensation: Add small amount of water
- Yellow leaves: Too much water or light
- Mold growth: Remove affected parts, improve ventilation
