The xaxim: a comprehensive guide to creating a sustainable tropical living wall in a terrarium

By Julien Hoffmann3 September 20223 min read

Xaxim is now one of the most effective materials for creating a natural and sustainable tropical terrarium. Both attractive and practical, it allows you to create a genuine living green wall capable of supporting epiphytes, mosses and certain tropical carnivorous plants.

If you’re looking to understand exactly what xaxim is, how to use it and why it has become a must-have for terrariums, this guide covers all the essentials.

What is xaxim?

Xaxim is a fibrous material derived from the root structure of tropical tree ferns. It comes in the form of rigid, naturally porous panels.

Its structure allows it to retain water whilst remaining well-aerated, which promotes natural root growth in plants and helps stabilise ambient humidity. Unlike a simple decorative panel, xaxim acts as a genuine living growing medium in a tropical terrarium.

Why use xaxim in a tropical terrarium?

Xaxim allows you to create vertical planting in a terrarium whilst making the most of the available space. It replicates the natural conditions of tropical rainforests and improves humidity management, as is the case with Neoregeliasfor terrariums.

When used correctly, it is gradually colonised by roots and plays an active role in maintaining the biological balance of the terrarium’s décor. It is now one of the best substrates for creating a vegetated backdrop or a structured tropical wall.

How do you install and secure the xaxim?

The installation of the Xaxim should be planned right from the design stage of the terrarium. Its position affects water flow, humidity and the stability of the décor.

It can be secured to a glass panel using a neutral silicone sealant specifically designed for aquariums, or to a rigid structure using a suitable mechanical fixing system.

For detailed information on methods, recommended materials and mistakes to avoid, see our comprehensive guide on how to secure the Xaxim in a terrarium in a durable and safe manner.

Correct fixing ensures the stability of the living wall and the longevity of the installation.

How should Xaxim be prepared and maintained?

Before installation, xaxim must be properly rehydrated to fully activate its absorbency. Incorrect preparation can lead to uneven drying or slow down the plants’ establishment.

Once installed, it requires regular moisture and simple monitoring of the microclimate.

You can find all the detailed steps in our article on preparing and maintaining xaxim in terrariums and tropical greenhouses. Proper care ensures that xaxim remains functional for many years.

Which plants should you grow on xaxim?

Xaxim is particularly well-suited to epiphytic plants and species that thrive in constant humidity.

You can grow tropical ferns, mosses, certain miniature orchids and several species of tropical carnivorous plants on it.

To find out which species are best suited and avoid making the wrong choice, consult our guide to plants for growing on xaxim. The choice of plants directly influences the success and appearance of the living wall.

The xaxim as a central feature of a tropical terrarium

Incorporated right from the design stage, the xaxim structures the vertical space, improves humidity distribution and provides plants with a substrate similar to their natural habitat.

It helps to create a cohesive, aesthetically pleasing and sustainable environment, whether in a decorative terrarium or a more ambitious tropical greenhouse.

Conclusion

The xaxim is much more than just a decorative backdrop. It is a living substrate capable of improving the stability of the microclimate and promoting the natural rooting of plants.

By understanding how it works, installing it correctly and choosing suitable species, it becomes the central element of a successful tropical terrarium. It provides superb growing media for mosses, sphagnum, ivy and many other plants.

FAQ on keeping xaxim in a tropical terrarium

Is the xaxim suitable for all terrariums?

Xaxim is particularly well suited to tropical, humid terrariums. It is less suitable for dry environments, as it requires consistent humidity to retain its properties.

How long does a xaxim slab last?

A properly installed and maintained xaxim can remain in working order for many years. Its durability depends on the quality of the fixing, the level of humidity and the ventilation.

Can you plant directly into xaxim?

Yes, the roots of epiphytic plants attach themselves to it naturally. It is not usually necessary to add any additional growing medium.

Does the xaxim require a lot of maintenance?

No, it mainly requires consistent humidity and monitoring of dry areas. In most cases, appropriate misting is sufficient.

Is the xaxim compatible with tropical carnivorous plants?

Yes, some tropical carnivorous plants thrive in its constant humidity and natural ventilation. However, you’ll need to adjust the watering and light levels according to the species.

Does xaxim need to be rehydrated before installation?

Yes, it is recommended that you rehydrate it thoroughly before installation in order to activate its absorbency and prevent it from drying out initially.
