Terrarium Making with That Flower Shop

terrarium making

I recently hosted a 13th birthday party at the shop for a super fun group of girls. The newly minted teenager (my honorary niece) wanted to do something with her friends that none of them had every tried before, so we decided terrarium making would be the perfect party activity. She loved the idea that everyone would make something awesome to take home and we reckoned it was the kind of activity that'd leave lots of room for chatting, snacking, and singing along to Taylor Swift.  

To make pulling the party together easier, I ordered terrarium making kits from That Flower Shop for each girl. They came beautifully presented in a timber box with each element neatly packaged inside. Doing things this way also turned out to be cost effective, as I didn't want to spend heaps of time and money sourcing large quantities of each separate 'ingredient' from local garden stores and the internet. 

If you've ever wanted to make your own terrariums, keep reading for all the materials and steps! 


Terrarium Making Materials:

  • glass vessel
  • plants
  • soil mix
    • 2 parts regular potting soil
    • 1 part peat moss
    • 1 part perlite
  • spagnum moss
  • activated charcoal
  • gravel
  • chopstickes
  • scissors
  • moss
  • bark, pebbles, larger stones for 'landscaping'

How To Make A Terrarium

1. Start with a clean, dry glass container.

2. Add a layer of gravel. The quantity will depend on the height of your container and the look you're after. 

3. Spring 2 - 3 pieces of charcoal. Charcoal whips orders away and your terrarium 'clean'.

4. Soak a handful of sphagnum moss in fresh water. Squeeze well and add a layer to your terrarium. This will create a barrier between the soil and the gravel. 

5. Now it's time to add soil and plants! Give your plants a once over to make sure there're no insects or diseased bits. Remove soil from around the edge of the root ball near the base of the plant and carefully untangle the bottom roots. Place the largest plants first, followed by progressively smaller ones.

6. When all the plants are in, firmly tamp down the soil. Cover with moss, orchid bark or pebbles, depending on the look you're after. Using cover like this prevents soil disturbance when watering and reduces evaporation later on.

7. Plants need to be watered in slowly with room-temperature water. Distilled water is optimal because the minerals in tap water can build up in the soil and leave residue on the terrarium glass. The soil is adequately saturated when it becomes dark all the way through. Any excess water that gathers in the drainage layer should be carefully siphoned off. 

8. Using a clean cloth, wipe down the sides of your terrarium glass. Pop your lid on if you have one, and set your terrarium somewhere with ambient natural light, but out of the way of direct sunlight. 

If you'd like to pick up a terrarium kit of your own, they're available on a custom order basis from That Flower Shop in Alderly. Or, if you'd like to buy a ready made version, they're available and ready to take home at Showroom.
