The Beginner's Guide to Sealed Terrarium Care: Simplified

In the realm of indoor gardening, sealed terrariums have carved a niche for themselves, offering a glimpse into the intriguing world of self-sustaining ecosystems. These glass-encased gardens not only accentuate the beauty of your indoor space but also require minimal upkeep, making them an excellent introduction to gardening for individuals of all ages, including children. But how simple is it to look after a sealed terrarium? Let's explore the basics of sealed terrarium care and shed light on whether it's an activity suitable for a young gardener.

The Essentials of Sealed Terrarium Care

A sealed terrarium is a glass container that is completely closed, housing a mini ecosystem of plants, soil, and stones. This enclosed setup recycles moisture and air, closely emulating the natural environmental cycle, which significantly reduces its maintenance needs.

Low-Maintenance Nature: The standout feature of a sealed terrarium is its low maintenance requirement. After the initial setup, there's little you need to do, making it a perfect project for children under adult supervision. They can learn about the ecosystem while enjoying the beauty of their miniature garden without the constant need for care.

Light and Temperature: Sealed terrariums perform best under indirect light, making them ideal for indoor settings away from harsh sunlight. A steady, moderate temperature suits them best, which is typically found in home environments. This makes it easier for children to find the perfect spot for their terrarium.

Occasional Checks: Regular, but infrequent, checks are vital to ensure the terrarium's health. Over-condensation or a dry appearance may require minor adjustments, such as opening the terrarium to air it out or adding a sprinkle of water—simple tasks that children can do with guidance.

Can a Child Care for a Sealed Terrarium?

Absolutely. With its low maintenance requirements and simple care instructions, a sealed terrarium presents an ideal opportunity for children to delve into the world of gardening. It encourages responsibility, patience, and a deeper understanding of nature's cycles. Children can easily manage the light monitoring and minor adjustments required, with occasional help or reminders from an adult.


Sealed terrariums not only add a touch of green to your space but also offer a fascinating, low-maintenance gardening experience suitable for all ages, including children. Their simplicity and the minimal care required make them a wonderful project for young ones to learn about nature's workings. By following the straightforward care tips and fostering a bit of patience and responsibility, children can successfully maintain a thriving sealed terrarium, enjoying the beauty and satisfaction it brings.


Q: How often should I open my sealed terrarium? A: Ideally, keep it closed to maintain its self-sustaining environment. If adjustments are needed due to excessive moisture or plant stress, opening it briefly is fine.

Q: What plants are suitable for a sealed terrarium? A: Opt for small, humidity-loving plants like ferns, mosses, or fittonia, which adapt well to the terrarium's environment.
