Mini Terrarium

Kids love miniature worlds! So why not let them create their very own mini terrarium to look after? Get creative!

What you need:

  • Glass terrarium or fish tank
  • River sand
  • Pebbles
  • Coir brick
  • Water
  • 10l bucket
  • Soil from your garden
  • Mini plants and succulents suitable for a terrarium
  • Moss
  • White river stones and/or seashells

Step 1:

Place a layer of river sand and pebbles, roughly 5cm deep, in the bottom of your container for drainage.

(Glass is impermeable, therefore you have to put something in the bottom that will allow the soil to drain instead of sitting in water. Plants that are sitting in waterlogged soil will die, so you need the soil to drain.)

Step 2:

Prepare the coir bricks according to the instructions on the pack: Soak a 1kg coir brick in 5l of warm water to help break it up and then add another 5l of water to thin it out. This will make 10l of coir fibres. Try to cover all the river sand and pebbles with the coir fibres and then add a layer of soil.

Step 3:

Arrange your plants in the container.

Try a few different arrangements of your plants. You’ll have to experiment and move them around until you get them the way you like them.

Once you’re sure the plants are where you want them, remove them from their containers and plant them into the soil.

Spoon extra soil into your terrarium. Use your hands to firm the soil around the plant roots, then smooth it out so that it’s relatively level.

Step 4:

Lay the moss on top of the soil around the plants.

Step 5:

You can decorate your terrarium using white river stones to cover up the soil in between the plants and the moss. You can even add a few seashells on top of the moss, if you have a few from your last trip to the sea!

Step 6:

Now it’s time to water your plants. Watering them right away moves the soil around their roots and helps them to grow in their new container.

Remember not to over-water!
