A terrarium serves as a piece of art and a healthy environment for plants. It can make any area much more appealing and is far simpler to maintain than potted plants. Read on for some inspiration for terrariums ideas that you can use to be creative and build yourself a beautiful indoor garden.

A terrarium is a little garden housed in a clear glass container. It contains soil, vegetation, pebbles, and a charcoal layer that purifies the air and water.

The container could be a clear glass jar, a fish tank, or a custom-made glass object.

In a terrarium, the plants and soil give moisture, which condenses on the glass walls and then drips back onto the plants.

A terrarium and a vivarium might appear remarkably similar. However, terrariums only support plants, not animals, while the latter acts as an animal's habitat. Terrariums can be sealed or open.

Open Terrariums

Open terrariums provide a less humid environment with better air circulation. They support the development of ornamental plants that prefer a drier climate.

Careful watering and a little more upkeep are needed for open terrariums than for sealed ones. Plants best suited for these terrariums prefer dry air, such as succulents. "Succulent" refers to a plant that stores water in its stem and leaves. They have evolved to flourish in arid soil with little rainfall. They may thrive in conditions with little precipitation.

Despite this, succulents still require some water to continue growing. They also prefer warm temperatures because the cold can harm them easily.

Closed Terrariums

A lid is attached to sealed or closed terrariums to form an independent habitat with a water cycle.

Plants discharge moisture into the air, recycling the nutrients they absorb from the soil. Sealed Terrariums shouldn't need watering. Plants that love humidity and water are best suited for these Terrariums, such as ferns.

Terrarium Plants

The ideal plants for a terrarium can fit inside it without coming in contact with the walls.

Plants that prefer moist soil typically thrive in terrariums, particularly sealed ones.

Leafy plants' foliage gives your glass container year-round colour and vibrancy.

It's best to steer clear of plants that have varying light requirements. Maintaining good growing conditions for both plants can be challenging if some prefer shade and others require intense sunlight daily.

Low-maintenance plants work best in terrariums because you don't want to stress over them and constantly rearrange them.

What You Will Need to Make a Terrarium

  • A glass jar or similar translucent container that allows light to enter

  • Little rocks for drainage

  • Utilizing activated charcoal to keep the water sanitary and stop dangerous germs

  • Rocks or stones for decoration

  • Use either basic or a speciality mix of potting soil for your chosen plants.

  • Air plants or succulents or small plants.


  1. Clean the container

  2. To guarantee proper drainage, add a layer of pebbles between 1 and 2 inches thick to the container's bottom.

  3. To prevent harmful microorganisms and maintain fresh water in the terrarium, sprinkle a thin layer of activated charcoal on top.

  4. To give the roots plenty of room for support, add the potting soil in a layer at least 2" deep.

  5. Add the most prominent plants first. Create a hole in the earth around the plant's roots, then gently press the plant into the hole. You can omit this step if you use air plants.

  6. Creatively arrange the plants. Plants should be placed from the back of tiny terrariums to the front. In this manner, you can have enough space without endangering the plants.

  7. Add small rocks or pebbles to the topsoil for decoration. This is where you may get creative and add small branches and other ornamental elements.

  8. Water the terrarium just a little.

  9. Place the terrarium where it receives indirect sunlight most of the day. But if your plants demand a different amount of light, adhere to that!

  10. Water open containers frequently, typically once every two weeks, before the soil becomes entirely dry. For this, you can use a laundry sprinkler or straw.

  11. Normally, sealed containers don't need to be watered. To let excess moisture out, you might need to remove the seal.
