At Leafage, we’ve always believed that nature can ground us, inspire us, and even teach us a thing or two about patience and care. And terrariums? They’re like tiny time capsules of life. But how long do they last?

The Terrarium That Lived for Over 60 Years (!)

One of the oldest known terrariums was planted by David Latimer in 1960, and it’s still going strong today. Can you believe it? This little closed ecosystem hasn’t been watered since 1972. It lives entirely off its natural cycle: sunlight, condensation, and a whole lot of plant magic.

This story isn’t just impressive — it’s a brilliant example of how powerful a well-built terrarium can be. With the right care (and a dash of love), yours could last for decades too.

So, How Long Can a Terrarium Last?

A well-designed closed terrarium can live for several decades. Some even say indefinitely, as long as the balance between light, moisture, and airflow is just right.

Open terrariums, often used for succulents or cacti, tend to have a shorter lifespan. They don’t recycle moisture in the same way, so they need a little more TLC.

What Makes a Terrarium Last?

Here’s what gives a terrarium that long life:

• Good drainage: A layer of stones or clay pebbles at the bottom helps prevent soggy roots.

• Activated charcoal: Keeps things fresh by filtering the water and stopping odours.

• Healthy soil: The right kind of soil gives your plants the nutrients they need.

• Balance of plants: Choose slow-growing, humidity-loving plants like ferns, moss, or fittonia for closed terrariums.

• Light, but not direct sun: Think bright, indirect light – too much sun and your plants might overheat.

At our Leafage terrarium workshops, we guide you through all of this step-by-step, so you leave not just with a beautiful terrarium, but with the confidence to care for it too.

Can You Really Leave It Alone?

Yes — and that’s the beauty of it. A closed terrarium waters itself. It forms its own mini water cycle, where moisture evaporates, condenses on the glass, and drips back into the soil. It’s a self-sustaining little planet.

That said, it's still a good idea to check in every now and then. Look out for too much condensation, mould, or unhappy-looking plants. A quick tweak can bring the balance back.

A Living Reminder to Slow Down

More than just décor, a terrarium is a mindful moment in a jar. It reminds us to slow down, breathe, and stay curious — especially in fast-paced workplaces or busy homes.

They also make wonderful gifts, office centrepieces, or wellbeing activities for team building and away days.
