How To Build A Terrarium

Terrariums are miniature gardens that can add a touch of greenery to any space. It’s a great way to bring the outdoors inside and create a peaceful environment. In this article, we’ll show you how to build a terrarium step by step.

What You’ll Need

Before we get started, let’s gather the materials you’ll need to build a terrarium. You’ll need a glass container, potting soil, rocks or gravel, activated charcoal, and plants.

Choosing a Container

The first step in building a terrarium is choosing the right container. You can use any glass container, such as a jar, bowl, or vase. Ensure that the container has a wide opening to make it easy to plant and maintain.

Preparing the Soil

Once you have your container, the next step is to prepare the soil. Use a high-quality potting soil that has good drainage. You can add sand or perlite to the soil to improve drainage.

Adding Rocks or Gravel

Before adding soil to the container, add a layer of rocks or gravel at the bottom. This layer will help with drainage and prevent soil from getting waterlogged.

Adding Activated Charcoal

Activated charcoal helps to keep the terrarium clean and fresh. It absorbs impurities and prevents odors. Add a layer of activated charcoal on top of the rocks or gravel.

Planting the Terrarium

Now it’s time to add the plants to the terrarium. Choose plants that thrive in a humid environment, such as ferns, mosses, and succulents. Arrange the plants in the container, ensuring that they have enough space to grow.

Adding Decorative Elements

You can add decorative elements to the terrarium, such as rocks, pebbles, and figurines. These elements can add interest and personality to your terrarium.
