How To Make Your Own Terrarium

If it's craft that involves gardening I MUST try it. Terrarium creating literally took over my life during the July school holidays. So once I started with one, I just wanted to keep on making more. What a fun addiction!

My two glass containers are great examples of what you can do with just a little. I used only two plants in each terrarium. The possibilities are endless as not all terrariums have lids, but it does help with the micro-climate eco-system; condensation moisture.

Large Jar: $23 from Its N Bits (O'Hollaran Hill, Adelaide)
Small Jar: $3 from Ikea



  • Large glass container
  • Small decorative pebbles
  • Activated charcoal or carbon (available at pet stores for pet terrariums/tanks)
  • Potting mix
  • Perlite
  • Small indoor shade loving plants
  • Decorations/Props (extra)
  • Water



Start with a clean dry jar.

Work in layers.

  1. Small pebbles at the very bottom for drainage, about an inch deep.
  2. Add a thin layer of activated charcoal; keeps your terrarium healthy and mold free.
  3. Mix a little perlite through the potting mix and add as the next layer.

Make sure you have enough soil for the plants' root system.

Using small indoor low light loving plants, reduce the root size by half before planting. Don't be scared to do this as the reduced root size will assist in the plant size for terrarium planting. They survive very well with reduced root size.

Make sure that the leaves do not touch the sides of the glass, if possible. This keeps the plants healthier for longer.

Top up with soil around the plants if needed, at planting time.

Add a little water to ensure that the mix is damp, but not soggy.

Place rocks, small toys (e.g. plastic horse, birds, miniature dolls house furnishings, etc.) if desired.

Replace lid.

Place your terrarium in a spot where it will receive indirect sunlight.

If plants are looking a little sad, check the soil moisture as they may need a little watering.


Watering Care

Watch your plants for the first week to make sure that they are coping.

Droplets on the glass is great because we know that the eco-system is working.  If the soil looks a little too wet, just leave the lid off for a couple of days to dry out.

If no droplets are forming on the glass, it may be time to add a little water.

Rotating the terrarium from time to time will ensure that your plants will grow straight.



  • You can add earth worms if you desire.
  • Use a spray bottle to water.
  • If using ferns, wrap moss around near roots to help keep moist.
  • Terrariums do best in cooler environments rather than hot direct sunlight.
  • The bigger/wider your terrarium is, the more landscaping and plants you can add.
  • Try a different type of terrarium: desert, moss-only, etc.
  • Great really creative and make yourself a terrarium necklace!
  • If you would rather buy a ready-made terrarium, due to import/export restrictions, you can only buy from within your country.
