This month I had a very special guest come visit me and my garden, gardening guru Michael Keelan who helped me create some amazing terrariums for Channel 7's SALife program (Sunday 5:30pm).


Terrariums are a great way to garden indoors especially if you live a busy lifestyle or you are away often. In fact these are a great gift for any one who loves gardening. This is even one for the lazy gardeners.

Being low maintenance and clean, a terrarium adds a beautiful living design element to any room that has naturally filtered light. Dress them up, get creative because there are no limits to your imagination when creating a terrarium.

And terrariums are so easy to create!

They really are like a mini rainforest, working on the principles of condensation, evaporation and precipitation. To get your terrarium working well there are some basic rules to follow so that the water cycle works effectively for your plants.

To get started:

What you will need

  • Clear glass or plastic container (with or without a lid)
  • Pebbles or coarse gravel
  • Activated charcoal (the smaller granular type from aquarium shops are ideal)
  • Potting mix (Premium or Cacti & Succulent Mix)
  • Plants
  • Mist Water Spraying Bottle with fresh water
  • Decorative objects (optional)

Terrariums on a Budget

Terrariums can be made from the simplest and cheapest materials all the way through to the high end fancy display. Use an old 2 Litre soft drink plastic bottle or even an old food jar. It can start that simple.

So I did my shopping around to find the best buys to get the most for your money.

Choosing your Jar

To activate the water cycle, choose a jar or container that either has a lid, side opening or rounded top opening to help the condensation return to the soil.

If you like tall plants then choose a tall container. Just remember that the pebbles and soil will raise the internal height.

The width of your container and plants are also important to consider as we do not want the foliage to touch the sides of the container or this will lead to rot and fungal problems. Simply snip back any leaves that don't quite fit whenever you see them touching a side.

Plant Choices

Standard Terrarium Garden
Head to your local nursery to the shade plants section and choose from the mini pots.
Terrariums rarely host flowering plants, but African Violets do very well.


Its not always the mini shade plants that take pride of place in a terrarium.
How about these other combinations:

Moss Garden
Moss gardens do not need any form of drainage as they thrive in boggy conditions. Just remember to check on it daily to see that it is still moist. Dryness will kill the moss off quickly. Mosses are not commercially available in South Australia, so it will be up to you to hunt in those darker moist areas of the garden.

Cacti and Succulent Garden
Not all cactus are spiky. Using a more open bowl to allow extra moisture to escape will keep these beautiful plants in the best condition. Always use the right potting mix blend.

Air Plants Garden
Air Plants do not need any soil to grow, just attach to a rock or piece of wood with florist wire or a dab or glue. If your container only contains pebbles, simply wiggle the plant into place between rocks very gently and place in a location that receives fresh air flow as the particles in the air feed Air Plants. A little light misting every now and again is recommended. Air Plants come in plastic containers are available at most nurseries and hardware store garden sections.

I hope this has inspired you to create your very own terrarium.
They make beautiful gifts as well as brighten up any room.

They only need a light spray of water every 2 to 4 weeks or as needed.

If you have made one, please let me know. You can follow me on Facebook and show off your terrarium creations there too.
