Upcycling Florariums

Origin of florariums

The florarium as a concept is not a new thing; it was already invented in ancient times. The word itself means a sealed glass container in which plants are planted. Initially, the term terrarium was used, and then because of the plants, it was renamed florarium, which was invented in 19th century England. During an experiment, an English doctor accidentally dropped a glass bottle on the soil, under which surprisingly wonderful plants grew quickly and, moreover, without care. There are currently three types of florariums: closed, open, and wide-mouthed glass containers.

The closed version is the most humid and sensitive to diseases, followed by the open and then the wide-mouthed ones. Narrow-mouthed containers provide slightly lower but relatively high internal humidity. If we want to create a completely closed florarium, it is very important to work with a sterile growing medium to exclude diseases from the glass. The most perfect soil combination for an average florarium is if we mix one part garden soil, one part peat, and one part perlite at home.

How does the process work in florariums?

Inside the glass, the plants create a closed ecosystem where the decomposing plant parts produce carbon dioxide and heat.

Under the influence of light, the plants photosynthesize, thus producing water and oxygen. This water condenses on the walls of the glass, allowing it to water itself.

In this case, it is especially important what shape the glass has, because the smaller its mouth, the better it can keep the liquid inside.

In this cycle, we only intervene if, for some reason, not enough fluid is being produced.

Caring for Florariums

Caring for florariums is a simple task that even novice or inexperienced gardeners can easily manage. Following the care advice below, our florarium can be a wonderful decoration in our environment for many years.

How Bottle Gardens Work

A well-planted glass container can develop into a self-sustaining ecosystem that can be left alone for weeks. As dying plant parts decompose, heat and carbon dioxide are produced while they transform into nutrients. Due to the greenhouse effect, the plant’s photosynthesis activates, converting carbon dioxide into water and oxygen. As continuous growth occurs, water condenses on the glass walls, maintaining balance and closing the cycle. We only need to intervene very rarely, perhaps if a plant overgrows, or if there isn’t enough condensation due to less light, when we might need to add a little water.

How to Make a Florarium

2 (1)

Choose a glass container!

The smaller its opening, the more self-sustaining the florarium will be.

1-2

Pour clay beads about a finger thick into the bottom of the glass!

This helps with ventilation on one hand, and on the other hand, all liquid drains here, which prevents it from rotting the roots in the soil.

1

Then fill 1/3 of the glass with soil mixture,

but in a way that it doesn’t mix with the bottom layer! Compact the layer at the end by gently tapping the glass!

Now think of your concept:

always build from outside inward, and place increasingly larger plants from outside toward the center! It’s advisable to put trailing or ground cover, small-growing plants around the edge, and a larger one in the middle.

3

Finally, it’s time for watering!

This can be done by spraying or pouring, it’s recommended to let it run down the side of the glass, which also cleans the glass wall.

The last and most important task:

love them and they will remain beautiful forever. :)

Main Caring Rules

Caring for florariums is a simple task that even novice or inexperienced gardeners can easily manage. Following the care advice below, our florarium can be a wonderful decoration in our environment for many years.

  • Place it near diffused light, where the temperature is relatively constant
  • Do not water for 2-3 weeks after purchase, only if it looks very dry (clay beads will indicate this)
  • Do not water the plants directly, spray them or very carefully water by holding it against the glass wall, but always give only a very small amount of water, preferably filtered Do not expose to direct sunlight, otherwise the glass will heat up and the plant will burn
  • They feel great under LED light too, if there isn’t much light in your apartment, it’s recommended to get an LED lamp
  • In winter, don’t place it near the window, because it can get cold and become moldy


Watering

  • How we water a specific florarium depends on many factors: the lighting conditions, the size of the glass opening, the type of plants, humidity, and the temperature of the environment
  • First, it’s advisable to place it in your home and observe during the first week how much condensation forms on the glass
  • Watering with filtered water is recommended, as the florarium environment is a more sensitive medium
  • Only give them a few drops of water, never hold them under the tap; if you have a pipette or a watering can with a thin spout, try to deliver the water as close as possible to the base of the plants
  • If you’re closing the florarium, always leave it open for a few days after watering so it doesn’t get too foggy

Frequently Asked Questions

Yes
In all cases, they need to receive light, but if it only fits on your desk, then lamp light will do, but it should receive at least 10 hours daily.

Yes
I only use live plants, I don’t even like to add non-organic things.

No
I put small shoots in it, or a plant that stays small, at most it just gets bushy and fills up the glass.

Directly no…
It happens that there are larvae or eggs in the soil mixture that hatch over time. They are not necessarily harmful to the florarium, but if you find a large slug in it, dig it out somehow.

The shape of the bottle determines this, some never, but some weekly. The smaller the mouth of the bottle, the less often it is needed, because the less liquid can evaporate from it. Of course, the cactus or succulent versions don’t need to be overwatered either, once a month is enough.

Place it outdoors only if it is not exposed to direct sunlight, otherwise the plant will boil and rot inside.

No
Only if it overproduces. Then, as far as you can reach the mouth of the bottle with scissors, you can easily cut off those shoots.

They produce heat and carbon dioxide, thereby helping to maintain the ecosystem within the florarium.

Personally, I don’t use it, as the fallen plant parts constantly replenish the necessary nutrients.

If you have the tools, try to fish out the moldy part: it is recommended to use the flexible part of a glass washing brush, which can be found in every household.

Either you have to carefully wash the inside of the glass with a syringe, or you have to rinse the glass washing brush well at home and clean the inside with it.

It’s up to you. I like it when it grows, but you can also cut it down, as you like.
