How to Make a Terrarium

Last night I hosted a long overdue craft night and decided to try my hand at making a terrarium. They are really quite simple to make and lovely to look at. I especially like seeing the layers in the glass jar, they remind me of those colored sand art projects from preschool days.

The trickiest part is assembling all your pieces. I found most of mine at the pet store, where in addition to activated charcoal (for getting rid of the icky bacteria that would otherwise form because of the lack of drainage), I found rocks and even plants that are suited best for aquariums and terrariums.

Also, terrariums can be either lidded or not. If not, they need to be watered a bit more frequently, once a week or so. If you do choose to make a mini eco system with a lid, your terrarium can go unwatered for a few weeks since the lid traps the moisture in.


  • glass jar / lidded or not
  • small rocks
  • activated charcoal
  • moss
  • potting soil
  • moisture-loving plants
  • accent pieces (rocks, driftwood, miniature figurines)

Once you have your supplies together, assembling the terrarium is easy-peasy. First layer an 1.5″ or so of small rocks, followed by a thin layer of activated charcoal. Add your moss on top of that, and your potting soil above the moss so that the jar is filled about 1/4 up with your bedding material. Finally, add your plants and decorative pieces and water sparingly. Enjoy your terrarium!
