Get the Supplies

  • The first thing you need is a transparent glass jar with a lid. You can choose the size, that’s up to you. If possible, choose a jar with a wide opening, as it will be easy for you to place stuff inside. 
  • The next thing you need is small pebbles for the base layer. These Peebles will create a drainage area for excess moisture. 
  • You need dried sphagnum moss to separate the pebble layer and potting soil. You can easily find dried moss in stores that sell plants. 
  • Potting soil is the top layer of the moss terrarium jar. Ensure the soil you use does not have weed roots; otherwise, they might grow in the jar too. Though weed growth might look good in the jar, it can hinder moss growth. 
  • You can add colorful rocks, small branches, or more decorative pieces to the jar. This is unnecessary, but if you like adding these things, keep them in your supply bucket.     

Get the Moss

Of course, you need moss for your terrarium jar. You can buy any variety of moss from plant stores. But this won’t be necessary, as you can find moss anywhere in a humid region. For people who live in dry regions, don’t worry; you can find moss outside as well. Just look for moss in areas that are shaded and damp. Don’t be surprised if you find moss in buildings too. 

Once you find a clump of moss, you can pluck it with your fingers. Don’t hesitate; you can wash your hands later. You can place your portion of moss in a zip-loc bag until you begin making the terrarium. Remember, your terrarium needs a very small amount of moss as it grows fast.

Making the Moss Tiny Terrarium 

  • The first step is to clean the jar. If the jar is brand new, then wash it with water. Make sure the jar is dry when you begin assembling the layers. 
  • You will construct the first layer of the terrarium with small pebbles. Depending on the size of the jar, fill it one to two inches deep to ensure proper drainage. 
  • The second layer of the terrarium jar is dried sphagnum moss. Make sure you cover all the rocks with dried moss. That’s it; you are done with the second layer too. 
  • You will use potting soil as the top layer. One to half an inch of potting soil will do the job, as moss doesn’t have traditional roots that go deep. 
  • Now it’s time to place the moss and decoration- if any- in the jar. You can place the decoration according to your desire. Water your terrarium with a sprayer until you see water in the bottom layer. Finally, loosely close the lid and place the jar in the sunlight.
