Cactus Terrarium

My first time trying out making a terrarium. I made this as a gift for my friend’s birthday since he likes cactus. I’m really happy with the output (feeling proud). I’m such a newbie in this kind of stuff so I wasn’t able to get the step-by-step photos because my hands were covered with soil.

Anyway, Ta-da! Here it is:


  • Cactus (I just cut some cactus in our garden. You can purchase different kinds / colours depending on what look you want to achieve)
  • Clear glass container (there are many to choose from. They vary in shapes and sizes)
  • Pebbles
  • Soil (I used organic soil)
  • Sand
  • Decorative stuff


  1. Clean the container and dry it completely. This will prevent fungi from growing inside your terrarium. It is also ideal to use something that has a wide opening—this makes moving and placing things inside more easily.
  2. Now, it is time to layer in the pebbles, soil and sand. It would be helpful if you already visualised what you want beforehand.
  3. Fill the bottom of the bowl with approximately 2 inches of pebbles/gravel then layer in about 4 inches of soil. I placed in the pebbles at the center then covered it with some sand before pouring in the soil.
  4. After that, you can now dig holes and place in your cactus.
  5. Play around with the decorations—I used wooden letter blocks that I bought from Papemelroti (P6 each). To make these wooden letters, I cut one end of the toothpick and glued it at the bottom of the blocks.


  • Use pair of tongs to move / place the cactus and other stuff inside.
  • Place the terrarium with indirect natural light.
  • Don’t need to water it daily, test the soil for dryness by touching it with your fingers. If your finger remains clean then it is time to water it.
  • Some recommends using horticultural charcoal to keep the terrarium from developing odours. But since mine is an open terrarium, it’s not necessary. If you still want to put charcoal, place 1/4 inch of it after the layer of pebbles/gravel.
