How to assemble your Do-It-Yourself terrarium

Making a DIY Bottle Terrarium + Closed Terrarium care tips

Creating your terrarium

Start cleaning your glass pot

Make sure your glass pot is really clean to make sure there are no bacteria left that could harm your plant terrarium.

The foundation of your ecosystem

A terrarium is a small world in your interior, home or office. A good foundation is therefore important. First, add a thin layer of potting soil, place the pebbles on top and finish it with the activated carbon.

Adding potting soil

Then add the remainder of the potting soil to the pot and distribute it over the surface. This build-up will ensure proper and natural water drainage and a good base for the plant roots to take root in later.

Placing moss and little plants

Place the moss all around in your pot on top of the soil in a way that leaves room for the plants. Carefully remove the little plants from the pot and place them in the potting soil. If the root ball of the plant is a bit dry, give it some extra water before placing it in your terrarium.

Decorating your terrarium

Give your pot a great finish with some more extra moss and maybe some own stones or terrarium attributes.

Giving a DIY terrarium as a gift?

Put your terrarium in a nice spot in your home and make sure it gets enough light, but avoid direct sunlight.

Taking care of your terrarium


The right light is essential for the health of your terrarium and plants. It is important that the plants don’t get too little light which can cause mold, or too much light which can cause the plants to burn. So place your terrarium close to a window, but avoid direct sunlight and for an even distribution of light turn it a quarter every 2 weeks.


A closed terrarium creates a humid climate which the plants use to keep themselves
alive. The plants perspire water in the form of vapor, this vapor partially condenses and causes droplets of water to appear on the inside of the glass.
These droplets then humidify the soil and provide a humid environment in which the plants thrive.

Still too dry? No worries. Even a closed terrarium may need some extra moisture every six months. If the soil feels dry, you can add 5 to 10 cl of water, depending on the size of your terrarium.

TIP: If your moss is no longer green take it out of the pot and put it in (filtered) water,
then squeeze it and place it back in your terrarium.


Sometimes there is too much condensation and the plants are barely visible.
In that case you can open your terrarium for 10 to 15 minutes to allow the excess moisture to evaporate.
Does the condensation keep coming back? Then move the terrarium to another place.


Our terrariums are only suitable for indoors and the best temperature is between 15 - 25°C (59 - 77°F).


With the right conditions of the terrarium, the plants can sustain themselves for years.
