Terrarium Layers

To build a successful terrarium, use the following soil layers;

• Drainage Layer – This layer drains and stores excess moisture, reducing the negative impact of growing plants in a container without drainage holes.
• Sphagnum Moss Layer – This layer absorbs excess moisture and is a barrier between the soil and drainage layers.
• Charcoal layer – This layer helps absorb any toxins that might impact the health of your plants or odors which might build up in the terrarium.
• Soil Layer – This is the base which will house your plants. Choosing appropriate soil is crucial for the health of your plants.
• Decorative Soil Layer – I like to add one or more layers of decorative material such as sand, decorative stones or shells between the soil. This gives your terrarium great aesthetic appeal.
• Plant Layer – These are the plants you house in your terrarium. Suitable plants differ depending on whether you are making an open or closed terrarium.
• Ornamental Layer – This layer adds to the decorative appeal of your terrarium.

While not all these layers are essential, they all have a role to play in creating an attractive terrarium that helps your plants to thrive. A drainage layer, soil layer and plant layer are essential. You can choose whether to use the others depending on your preference and the type of terrarium you are building.
