Fact Sheet: Caring For Terrariums

Starting a Terrarium? Here’s our “How to Guide”:

We have everything required, and if you ask nicely we’ll even put it together for you. Here’s what you’ll need:

  • A suitable glass container, with or without a lid
  • Medium to small sized pebbles
  • Horticultural Charcoal
  • Sphagnum Moss
  • Potting Mix 
  • Small plants

Step 1: Pebbles

Medium to small sized pebbles are placed on the bottom of your Terrarium to form a sump for water to drain into.

Step 2: Horticultural Charcoal

Horticultural Charcoal acts as the Terrarium’s filter. 

Step 3: Sphagnum Moss 

A layer of Sphagnum Moss on top of the charcoal helps to stop top layers washing through to the bottom. 

Step 4: Potting Media

This is the layer that you will plant into. Use a good quality Potting Mix such as Pot & Peat. Alternatively, use Palm Peat or Peat Moss with a bit of sand or fine gravel added for drainage. 

Step 5: Top Layer

Finish off with a layer of sand, pebbles, moss, or small ground covers such as Baby’s Tears. 

Suggested Plants:

For a Terrarium with no lid, use Cacti, succulents, or wide leaved Tillandsia. For a Terrarium with a lid, use ferns, moss, Baby’s Tears, Pot Bellied Figs, or small plants like African Violets. Avoid plants that have a high light requirement.


Place your Terrarium near a bright window away from direct sun, mist when condensation stops forming on the sides of the glass. For Cacti or Succulents let the Terrarium dry out properly between watering.
