How To Make A Terrarium Jar

If you want to add a touch of green to your home or office, a terrarium jar is a great way to do it. Not only is it easy to make, but it also requires minimal maintenance. In this article, we’ll take you through the steps of how to make a terrarium jar.

What is a Terrarium Jar?

A terrarium jar is a small, enclosed environment that contains plants. The jar can be made of glass or plastic and can be any size or shape. The purpose of a terrarium jar is to create a mini-ecosystem that is self-sustaining. The plants inside the jar create oxygen and remove carbon dioxide, while the moisture inside the jar creates a humid environment that the plants thrive in.

Materials Needed

Before we get started, let’s gather the materials we’ll need. You’ll need a glass or plastic jar with a lid, potting soil, small rocks, activated charcoal, and small plants. You can also add decorative elements like moss or figurines to make your terrarium jar unique.

Step 1: Add Rocks to the Bottom of the Jar

To create proper drainage for your terrarium jar, add a layer of small rocks to the bottom of the jar.

Step 2: Add Activated Charcoal

Next, add a layer of activated charcoal on top of the rocks. The charcoal will help keep the environment inside the jar fresh by absorbing odors and toxins.

Step 3: Add Potting Soil

Add a layer of potting soil on top of the activated charcoal. Make sure the soil is deep enough to accommodate the roots of your plants.

Step 4: Add Plants

Now it’s time to add your plants. Choose plants that are small and don’t require a lot of sunlight. Some great options include mosses, ferns, and succulents. Arrange the plants in the soil, making sure they have enough space to grow.

Step 5: Add Decorative Elements

If you want to add some personality to your terrarium jar, now is the time to do it. Add decorative elements like moss, small figurines, or colored sand.

Step 6: Water the Plants

Once you’ve added everything to your terrarium jar, give the plants a good watering. Be careful not to overwater, as the jar doesn’t have drainage holes.


Q: How often do I need to water my terrarium jar?

A: You only need to water your terrarium jar when the soil is dry. Depending on the environment, this could be anywhere from once a week to once a month.

Q: Can I put my terrarium jar in direct sunlight?

A: No, it’s best to keep your terrarium jar out of direct sunlight. The jar can act like a magnifying glass and burn the plants inside.

Q: Do I need to fertilize my terrarium jar?

A: No, you don’t need to fertilize your terrarium jar. The soil and plants inside will create their own mini-ecosystem.


With just a few materials and some creativity, you can create a beautiful terrarium jar that will add a touch of green to any space. Remember to choose small plants, add decorative elements, and water sparingly. With proper care, your terrarium jar will thrive for years to come.
