How to care for your terrarium
Our tips for helping it grow healthy and strong
A terrarium is a small green oasis that brings a touch of nature into our homes. Originating from miniature gardening techniques, a terrarium is a microenvironment that can host tropical foliage plants or succulents. At our company, we've chosen to offer a variety of terrariums to suit every taste and setting.
Where to place it
Place your terrarium in a bright room, but away from direct sunlight. The glass amplifies heat, and the leaves inside can burn within a few hours. An east- or north-facing window is perfect; a south-facing window is fine if the terrarium is 1-2 meters away.
How to maintain humidity
Humidity is essential for the well-being of the little plants in the terrarium. Check the inside walls: if they're foggy, the humidity is right. If the glass is completely dry, add 2-3 sprays of room-temperature water with a mister. If water is dripping heavily, open the lid (if closed) for 24 hours. Mist the substrate directly with low-mineral water, avoiding pouring water over it to prevent waterlogging.
Ideal temperature
The terrarium thrives in an environment with temperatures between 18 and 24 degrees Celsius. Avoid exposing it to temperatures below 10 degrees or above 30 degrees to ensure the health of the plants inside.
Ventilation and cleaning
To keep your terrarium healthy, it's important to ensure good ventilation. If the terrarium is closed, open the lid once every 7-10 days for 30 minutes to refresh the air and prevent mold. Never cover open terrariums, especially those with succulents, as they need dry air. Every 2-3 months, remove dry leaves or decaying parts with long tweezers and clean the glass from the inside with a soft, dry cloth when condensation allows.
Our final tip
Caring for a terrarium is a rewarding experience that requires just a little attention and love. Observe your small plants and learn to recognize the signs they send you: over time, you'll become an expert at keeping your little green ecosystem healthy and thriving.

- Light
- Bright indirect light · Place your terrarium in a bright room, but away from direct sunlight. The glass amplifies heat, and the leaves inside can burn in just a few hours. An east- or north-facing window is perfect; a south-facing window is fine if the terrarium is 1-2 meters away.
- Watering
- 14 days in summer · 30 days in winter · Mist the substrate directly with non-calcareous water (rainwater, distilled, or filtered). Never water with a stream: you risk water pooling at the bottom of the glass. · Check the inner walls: if they're fogged up, the humidity is right. If the glass is completely dry, add 2-3 sprays of room-temperature water with a mister. If water is dripping heavily, open the lid (if closed) for 24 hours.
- Temperature
- 18 °C minimum ideal · 24 °C maximum ideal · 10 °C minimum tolerated · 30 °C maximum tolerated
- Humidity
- High inside the terrarium · 60% minimum · 90% maximum
- Fertilizing
- No regular fertilizing: the terrarium is a self-sustaining microenvironment. If you notice slower growth after 6-12 months, use half the dose of liquid fertilizer for succulents (for succulent terrariums) or foliage plants (for tropical terrariums), diluted by a further half. · Spring-summer · 90 days
- Propagation
- Not applicable · The terrarium is designed as a stable arrangement. When a small plant grows too large, prune it or replace it.
