A little moss, earth, a few pebbles, a small tree like a ficus... the terrarium took shape at the bottom of a large transparent glass jar, to delight the eyes of young and old alike.

This confined indoor mini-garden requires a little maintenance and needs to be set up in a particular location.

When should a closed terrarium be opened?

Plants that thrive in heat and humidity are placed in a closed terrarium.

The lid can be made of glass, cork, plastic... This type of terrarium is intended to accommodate tropical plants, and recreate an environment with high humidity (above 70%).

If the condensation appears slightly and then slowly fades, there is no need to open the terrarium or try to remove it with a cloth.

It's completely normal, the microcosm lives and regulates itself.

On the other hand, too much water in the terrarium or a high temperature can cause significant condensation or the appearance of large drops on the walls, sometimes to the point of not seeing the interior too much.

It is then advisable to remove the lid and leave the terrarium in the open air for about an hour, the time that the water evaporates and that the miniature garden regains its balance, in order to avoid any appearance of mold. or undesirable bacteria.

Where to put a terrarium?

Several factors must be taken into account to properly position a terrarium.

  • The light

The terrarium hosts plants, so it must be placed near a window (maximum one meter away).

Plants must be exposed to light so that photosynthesis can take place properly.

A curtain can act as a barrier if the window is too close, protecting the plants.

The sun's UV rays will thus arrive less brutally in the event of high temperatures.

In summer, and also in spring if it turns out to be very mild and sunny, it is advisable to move the terrarium away from the light area to maintain a relatively gentle and indirect distance.

This precaution prevents a magnifying effect on the glass, the sun will not burn the plants, the leaves.

It also avoids overheating the inside of the jar.

Conversely in winter: bring it closer so that the plants can absorb the light as much as possible, which is less intense and of shorter duration at this time.

It is recommended to turn the jar regularly so that all the plants benefit from the same light intensity.

If there are many of them in the terrarium, turn it over by quarters.

  • Temperature

The room in which you put your terrarium should be at room temperature, neither too cold nor too hot.

It must be between 14 and 26 degrees approximately to preserve the ecosystem.

Be sure to respect the right temperature, especially if it is a closed terrarium.

It is indeed generally composed of plants evolving in tropical environments, therefore in a hot and humid atmosphere.

How to properly water a terrarium?

The terrarium regulates its hygrometry with the water cycle: the roots provide water to the plants which, via the stomata placed under their leaves, release water vapor (perspiration).

But for a good balance, the contents of the terrarium will sometimes need the help of your green thumb in the event of insufficient water.

The latter must be without limestone, so avoid that of the tap.

Prefer mineral water or rainwater, if you have been able to keep it after the last rainfall.

The water must be sprayed diffusely and sparingly at floor level, without however touching the other compositions.

If it is an open terrarium, in winter, watering once a week will be enough against two to three depending on the temperatures in summer.

If it is a closed terrarium, the frequency varies between two and four times a year.

In both cases, the color of the foam can be used as an indicator.

If it retains its green color, watering is not necessary.

If it turns pale, on the contrary, it means that it lacks water.

Advice

It is better to have less than too much water in the terrarium.

Stagnation can affect his well-being.

However, if you are wondering and want to be sure that the terrarium has all the necessary water, you can, once or twice a month, check that the base of the small central tree is slightly damp and advise as appropriate.

If it is a little wet, no need for watering, a little dry, add, with a spray bottle, a little water without limestone on its base as well as on the other plants which surround it and near the walls so that the earth can also absorb it when it has gently fallen.

Should the plants in a terrarium be pruned?

As long as the plants are in good condition and their color remains as it should be, there is no need to prune them.

They follow the normal course of their growth.

On the other hand, if the latter brings them to touch the glass wall of the terrarium, it is time to take his tool (a pair of scissors, a small pruner) to cut the leaves at the base.

Then, for better healing of the plant in question, remove the cover so that the air allows it to regenerate and replace it after 24 to 48 hours depending on the size of the plant.

Advice

Regularly remove dead leaves to preserve other plants.
