How to Plant a Terrarium | from Blue Bells and Cockle Shells

A terrarium is a mini indoor garden and is a fun and easy way to add a little greenery to your home or office. They are easy to create and depending what plants you choose, easy to care for. To grow a terrarium, you just need:

  • Container, lidded or not (you don’t need a formal terrarium, a glass jar, vase, bowl, or any other glass container works just as well)
  • Small rocks or pebbles
  • Activated charcoal
  • Sphagnum moss, dried (optional)
  • Soil
  • Plants (all plants for each terrarium should have similar moisture, light, and nutrient requirements)
  • Decorations
  • Mister
  • Fertilizers that are appropriate for the plants you are growing

  • Cover the bottom of your terrarium container with a layer of small rocks or pebbles. These are essential for drainage and aeration.

  • Add a thin layer of activated charcoal (I usually make my layer thicker than I did with this terrarium, but this was all that was included with my terrarium kit and I didn’t have any other charcoal in my house). This layer helps to keep odor under control.

  • Add a thin layer of sphagnum moss. This layer is optional and a bit controversial. The main purpose of sphagnum moss is to keep soil from falling to the bottom of your container. Some people actually put this layer before the charcoal, but I’ve always put it afterwards and have seen others do this also. In addition, though I had never read this until recently, but a lot of people soak the dried moss in water, then ring it out some, before putting it in their terrarium.

Special Types of Terrariums:

  • Air plants – do not spread roots, so do not need soil. They should not be heavily watered either, so I generally skip the charcoal, sphagnum moss, and soil layers with these types of terrariums

  • Marimo and water plants – you can skip the charcoal, sphagnum moss and soil layers with these terrariums (should these actually be called aquariums?)
