A Moss Terrarium Built Around Curved Bark with Natural Insect Galleries

The bark is very light, so there is no need to use glue to hold it in place. The natural stickiness of the red clay is enough to keep the bark attached.

This is actually just an ordinary piece of bark that I picked up by the roadside. It is fairly sturdy.

One thing I especially like about this piece is the pattern on its surface. It is covered with natural insect galleries—winding marks created by insects or larvae living and feeding beneath the bark. These patterns give the bark even more texture and make it look naturally aged.

When bark is used as the main structure in a moss terrarium, people usually choose softer bark with a flat back. But this piece is curved.

I personally really like curved bark, and this is not the first time I have used it in a moss terrarium.

When it is arranged properly, curved bark can create a very natural look, almost as if the shape was created by nature itself.

I should mention that this piece of bark was simply picked up outdoors. I did not treat it before putting it into the terrarium.

So yes, it grew mold.

I introduced some springtails, and within about one to two weeks, the mold on the bark had completely disappeared.

If you want to avoid this, it is much better to pretreat the bark first by boiling it in water.

Speaking of that, cinnamon bark is actually a pretty good option too. You can boil it first and still use it afterward.

And yes, I really have tried that.

How I Made It

First, I applied several lumps of red clay directly onto the glass and pressed the first piece of bark into place.

Then I added more red clay around the sides and edges of the first piece and attached the other two pieces of bark.

Because the bark is curved, there are fairly large gaps between the edges of the bark and the glass.

That is not a problem. Just use more red clay to fill the gaps.

Once the bark was in place, I attached pieces of Leucobryum moss to the red clay one by one.

There is also a video tutorial, so if this part is difficult to understand from the description alone, the video will make it much clearer.

The Bottom Layer

The rest is my usual setup.

I started with a layer of lava rock at the bottom.

Then I added a layer of sphagnum moss.

Next came a layer of Akadama soil on the surface.

Finally, I covered the ground with fissidens moss.

Mist everything with water, close the terrarium door, and it is finished.
