What you'll do

  1. Learn how a terrarium works. How a sealed jar keeps its own water cycle going, and which plants thrive in it.
  2. Build the foundations. Lay the drainage, filter and soil layers that keep your garden healthy for years.
  3. Plant and landscape. Choose your plants, then add moss, stone and natural details to create your own miniature landscape.
  4. Seal it and take it home. Leave with your finished terrarium and know exactly how to look after it.

  • A 20cm × 20cm glass terrarium jar
  • All plants, moss and building materials
  • Hands-on guidance from our team throughout

Masterclass FAQs

Where is the masterclass held?
At our studio at Unit 76, Coal Drops Yard, King's Cross, London N1C 4DQ, on the upper viaduct level. It's a few minutes' walk from King's Cross St Pancras station, and lifts go up to the viaduct level. Full directions are in your booking confirmation.
How long does it last?
The Terrarium Masterclass runs for about two hours.
Do I need any experience?
None at all. The class is fully guided and beginner-friendly, whether it's your first terrarium or your fifth.
How do I look after my terrarium afterwards?
Closed terrariums need very little care: indirect light and the occasional check. You'll get care instructions on the day, and our Terrarium Care Guide covers everything in detail. If anything goes wrong, just get in touch.
Can I buy the masterclass as a gift?
Yes. Buy a gift card and the recipient can redeem it against any workshop and date they like.
