So, you’ve got yourself a gorgeous terrarium, nice one! Closed terrariums are like little bottled worlds, creating a mini rainforest right inside your home. They lock in moisture, recycle air, and provide the perfect self-sustaining environment for tropical plants.


These little glass worlds are not only stunning but also surprisingly low-maintenance. That said, where you place your terrarium can make all the difference between a thriving mini jungle and a sad, foggy one. So, let’s make sure your plants stay happy and healthy with the perfect spot!




Light: Keep It Bright, But Indirect 


Tropical plants love plenty of light, but that doesn’t mean they are sun worshippers!  Place your terrarium in a bright spot with indirect sunlight, near a window but not right on the sill where harsh rays can overheat the glass.



Best spots for ideal light:


  • A bright windowsill but avoid harsh afternoon sun.

  • Near a north or east facing window, gentle light, happy plants.

  • On a shelf or table with good natural light, just keep it away from dark corners!

Temperature: Keep it cosy


Terrariums aren’t fans of dramatic temperature swings. Keep them away from radiators, air conditioning, or drafty windows. Extreme heat can cook your plants, while cold drafts might slow their growth.



Safe, stable spots:


  • A bookshelf, away from heating or cooling sources.

  • A desk or coffee table, adds greenery without stress.

  • A bedside table, waking up to some greenery? Yes, please!

 



Humidity: Create a Mini Rainforest


Since closed terrariums trap moisture, placing them in already humid areas (like a steamy bathroom) can lead to excessive condensation and unhappy plants. If you notice constant fogging or mould creeping in, move your terrarium to a less humid spot or crack the lid occasionally to let in some air flow.



Best humidity levels:


  • Living rooms & offices, moderate humidity, perfect balance.

  • Bedrooms, calm, stable conditions.

  • Kitchens, looks great, just keep away from the hob!

Keep It in Sight!


Let’s be honest, terrariums aren’t just for the plants, they’re for you to enjoy! Place yours where you can admire it daily. But if you’ve got curious pets or kids, keep it somewhere safe (no one wants a shattered glass garden and therefore the extra cleaning up!).



Best visible & safe locations:


  • At eye level on a shelf, show it off!

  • On a sturdy table, accessible but safe.

  • Inside a glass cabinet, protection with a stylish touch.

 




The Perfect Placement Checklist


✔ Bright, indirect light - no direct sunburns!

✔ Stable temperature - avoid heat sources and drafts.

✔ Moderate humidity - skip the steamy bathroom.

✔ Safe from pets, kids, and accidental knocks – save the clean up!

✔ Visible and enjoyable - because you deserve to admire it!


Follow these simple tips, and your terrarium will thrive for years to come! 🌿

 



Final Thought: Trust Your Space



Every home is different, so experiment! If your terrarium seems unhappy, e.g. too much condensation, yellowing leaves, or mould, just adjust its location. A little trial and error goes a long way in keeping your miniature world thriving.
