Succulent terrariums are a beautiful and low-maintenance way to bring greenery into your home. However, even these hardy plants need the right care to thrive. Whether you’re a beginner or an experienced plant lover, this guide will walk you through everything you need to know about caring for your succulent terrarium, from proper watering to troubleshooting common issues.
🌞 Light Requirements: The Key to Healthy Growth
Succulents love light, but in a terrarium setting, it’s important to strike a balance to prevent scorching or stretching.
Best Light Conditions for Succulents
✔ Bright, indirect sunlight is best. A south- or west-facing window is ideal.
✔ If placing in direct sun, monitor for overheating, especially in glass terrariums.
✔ If your home lacks natural light, use a grow light to supplement.
Signs of Too Much or Too Little Light
🔹 Too much light → Leaves become sunburned, turning white or brown with dry patches.
🔹 Too little light → Succulents stretch out, becoming leggy and losing their compact shape.
Solution:
• If your succulent is stretching, move it to brighter light and rotate the terrarium regularly.
• If leaves are sunburned, relocate it to filtered sunlight or provide shade during peak hours.
💧 Watering: The #1 Cause of Succulent Problems
Overwatering is the most common reason succulents die in terrariums. Since most terrariums don’t have drainage holes, it’s important to be mindful of how much water you add.
How to Water Your Succulent Terrarium
✔ Water lightly every 2-3 weeks, depending on the season (less in winter).
✔ Use a spray bottle or dropper to control the amount of water. Avoid pouring water directly over the plants.
✔ Always check that the soil is completely dry before watering again.
Signs of Overwatering & Underwatering
🔹 Overwatering → Leaves turn mushy, transparent, or black; mold or fungus appears in the terrarium.
🔹 Underwatering → Leaves wrinkle or dry up at the base.
Solution:
• If overwatered, remove any rotting leaves and allow the soil to dry completely before watering again.
• If underwatered, lightly mist the soil and check moisture levels regularly.
🌡️ Temperature & Humidity: Creating the Ideal Environment
Succulents thrive in warm, dry conditions—similar to their natural desert habitat.
Best Temperature & Humidity Levels
✔ Keep between 60-80°F (15-27°C) for optimal growth.
✔ Avoid placing your terrarium near heaters, radiators, or cold drafts.
✔ Succulents prefer low humidity—avoid sealed containers that trap moisture.
Preventing Excess Humidity
🔹 If your terrarium traps too much moisture, you may notice condensation or mold growth.
Solution: Remove the lid (if applicable) for a few hours to allow airflow.
🍃 General Maintenance: Keeping Your Terrarium Looking Fresh
To keep your succulent terrarium in top condition, follow these simple maintenance tips:
✔ Remove dead leaves at the base of the plant to prevent rot.
✔ Rotate your terrarium every few weeks for even light exposure.
✔ Prune overgrown succulents by snipping leggy stems and replanting cuttings.
✔ Clean the glass periodically to remove dust and water spots.
🛑 Common Problems & Solutions
1. Why Are My Succulents Getting Mushy and Dying?
🔹 Problem: Overwatering is the main culprit.
✅ Solution: Remove any rotting plants, let the soil dry, and cut back on watering.
2. Why Are My Succulents Growing Tall and Leggy?
🔹 Problem: Not enough light—succulents stretch toward the light source.
✅ Solution: Move to brighter light or supplement with a grow light.
3. Why Does My Terrarium Have Mold?
🔹 Problem: Excess moisture and lack of airflow.
✅ Solution: Reduce watering, remove any mold, and air out the terrarium by leaving the lid off for a few hours.
4. Why Are the Leaves Drying Up?
🔹 Problem: Natural aging or underwatering.
✅ Solution: If the base leaves dry up, this is normal—just remove them. If all leaves are drying, increase watering slightly.
📌 Succulent Terrarium FAQ
How often should I water my succulent terrarium?
Water every 2-3 weeks, but always check that the soil is dry before adding more water.
Can I use a closed terrarium for succulents?
Closed terrariums trap humidity, which succulents don’t like. It’s best to use an open terrarium for succulents.
What type of soil is best for succulent terrariums?
Use a well-draining cactus/succulent mix. Avoid regular potting soil, which retains too much moisture.
Can I mix different types of succulents in one terrarium?
Yes! Just make sure they have similar light and watering needs. Avoid pairing succulents with tropical plants that require more humidity.
How do I fertilize my succulent terrarium?
Succulents don’t need frequent feeding, but you can use a diluted cactus fertilizer once in the spring and summer months.
🌿 Final Thoughts: Keep It Simple!
Succulent terrariums are low-maintenance, but they still need the right balance of light, water, and airflow to thrive. Keep an eye on your plants, adjust care as needed, and enjoy your beautiful, miniature desert garden!
