Terrarium Making Lesson

copyright Kindra Clineff from The New Terrarium

Okay, here comes the pep talk: You can do this. Your kid can do this. Your grandmother can do this. Your hamster probably can’t.

Why do this? Because this terrarium will rescue your life. You will find peace. The world will be a better place. Nature will seep into all the little nooks and crannies of your existence. Your family will thank you (but I make no promises about the kids ceasing to whine). Creativity will reign. Winter will be bearable. All this from a terrarium.

What do you need to make a terrarium? Just:

  • A glass container (okay, you can use plastic, but it won’t sparkle). Preferably find a container that you can fit your hand into.
  • Terrarium plants
  • 3/8 inch pebbles
  • Horticultural charcoal (acquire at a garden center or aquarium supply store)
  • Potting soil mix (light African violet mix works — I use an organic mix)
  • Watering can
  • Nature objects like seed pods, lichen-covered sticks, seashells, whatever grooves you
  • Gloves (Always wear gloves. Don’t argue with me)

Ready? Here’s how to do it:

  • Put on the gloves
  • Mix some water into the potting soil before you start
  • Pour (or scoop) 1-2 inches of pebbles into the bottom of the glass container
  • Add a small handful of horticultural charcoal
  • Mix it together with the pebbles
  • Add a separate layer of 2-3 inches of soil
  • Dig a hole in the soil to receive your first plant
  • Tuck that baby into the hole, firming it in. Really firm it in. Firm it in again.
  • Repeat for other plants
  • Add the nature objects
  • Water the terrarium lightly
  • Put the lid on
  • See, I told you = Peace

    Can you give me a few ideas as to what plants go well together in a closed terrarium? I particularly like the one you have shown by the bed. Do you ever do any with miniature trees (natal plum, boxwood, or petite point)? I would like 2 or 3 to use a centerpiece for my dining room. Thank you so much and I love your website!

      You know, using miniature trees to create a mini scene is a really, really brilliant idea, Ashley. I think the Natal plum would probably work. I’ve never tried boxwood, but I bet it would survive just fine. I often use Serissa and I find that works very well plus it often blossoms. I’ll have a blog up on plants for terrariums by tomorrow.Thank you so much for the kind words. I love doing this!

    I love this! I saw you on CBS Sunday Morning show and could not wait to try making one myself! I had a few questions… how much light do these need? Can I place anywhere in a room, or do they need to be by a sunny window? Also, I didn’t see you mention watering. How much/often would I need to water? Thanks so much for your help! 🙂

    • Tovah Martin says:

      Hey Jennifer, Thank you so much. The CBS show was REALLY fun to tape. Terrariums prefer indirect light = a bright sunny window will roast them so it’s not good. They need watering very infrequently, depending upon whether they’re closed or open. You’ll have to judge by the weather. For the full scoop, I wrote a book — The New Terrarium!
