A terrarium is equipped with its own microclimate. For terrarium, a completely enclosed container or a container with a small opening or even a cover has been used. 

As a result, a terrarium resembles a greenhouse. 

In the same way as sunlight enters the atmosphere warms the Earth's surface, sunlight hits the glass and warms the air, soil, and plants. 

Like the Earth's atmosphere, the glass absorbs some of the heat.


A terrarium is a transparent glass or plastic container filled with small plants that can be open or tightly closed. 

A transparent, open container for growing and displaying plants has also come to be known as a terrarium.

 Some small plants that do not adapt well to typical home environments can most benefit from terrariums. 

They provide a novel way to grow a large number of plants with little effort when properly planted and assembled.

Types of Terrarium:- 

Terrariums are divided into two categories, each defined by the container used.

1. Open-system terrarium- Using a big glass bowl or another container with a wide opening. An open-

system terrarium needs more frequent watering and has lower humidity levels than a closed-system terrarium.

2. Closed-system terrarium- Using a container that is closed (or nearly closed). It's best to use a lidded jar with a small mouth. 

The environment needed for moisture- and humidity-loving plants will be maintained in these containers.

Choosing of containers for terrarium Clear glass or plastic can be used to make a terrarium jar. 

Almost any container, like fish bowl, a fish tank, a brandy snifter, an old glass jar or container, a glass mug, or a bottle. 

Transparent covers can be used on closed containers.

Selection of plants for terrarium:- 

In a terrarium, you can grow a wide range of native and tropical plants. Native mosses and lichens may be used instead of combining all forms of plants in the same terrarium, which is not a good idea. 

Lowto medium-light-loving plants are included. Make an effort to get a variety of leaf sizes, textures, and colours. Make sure they fit in your terrarium comfortably, ideally without touching the edges.

Open-system terrarium plants (cacti and succulents) – Aeonium, Aloe vera, Burro's tail, Cactus, Crown of thorns, Devil's backbone, Echeveria, etc.

Plants acceptable for  the two open- and closed-system terrariums - African violets, Norfolk Island pine, Orchid, Anthurium, Ardisia, Palms, Artillery fern, Peperomia, Baby's tears, Philodendron and others.

Growing medium for terrarium

The growing medium in terrariums would have to be clean, well-drained, and organic matter content. 

For these purposes, a growing medium  mix with one-part peat moss and one-part rich garden soil is used.

 A prepackaged peat-lite mix (a mix of peat moss, vermiculite, and perlite) is also an excellent option.

Accessories for terrarium:- 

Rocks, gravel, and other natural materials such as bamboo or sticks, woods, seedpods, bark and mosses make attractive terrarium accessories. 

Frogs, fungi, and snails made of ceramic can help to create a natural environment. The inclusion of accessories is purely a matter of taste. 

However, don't overdo it with the accessories, particularly if they're in bright, unnatural colours.

Assembling the terrarium :- 

A few hours or a day before construction, water the plants in their original containers.

Before using the terrarium container, make sure it's clean.

Fill the bottom of the container with 1 inch of gravel.

Add about a quarter inch of charcoal at a time.

Add about 2 inches of growing medium to the container. 

Gently take plants out of their original pots and loosen up the medium at the all sides of root ball.

Using your side, gently open up the root ball to divide the plants into smaller parts.

Pruning is needed if foliage’s contact the container's sides or lid.

Place the tallest plants in the middle, with the rest of the plants arranged around them.

Ensure that the terrarium is well-watered. Mist the inside walls of the glass jar with a mist spray. 

Water may be applied to the terrarium at carefully because it should not be drained from the terrarium.

Tear big moss parts into small pieces and disperse them in patches around the soil surface. Some 

patches may be strewn with chopped bark. Finally, apply some finishing touches by using some decorative items.

Care of terrarium:- 

 Watering – Water is usually not needed for 4 to 6 months in a closed terrarium. However, in open 

terrariums water require occasionally but not as necessary as other houseplants. Over watering promotes root infection by causing excess moisture in the gravel and charcoal. 

Since terrariums have no external drainage that’s why light watering are needed.

 Light – Direct sunlight should not be allowed to enter an open or closed terrarium. 

Many plants would be harmed by direct sunlight because it causes heat accumulation. 

Artificial light for sixteen to eighteen hours/day is needed if the terrarium is in a low-light areas

 Pruning – Many plants in terrariums eventually outgrow their confines. 

Trimming them back quickly gets them into line and quite often encourages edge growth, which aids in plant filling out.

 Fertilization - After planting, wait at least a year before fertilising. If the plants appear yellowish and lack vigour after the first year and there are no other obvious problems, a light water soluble fertilisation may be needed.

Other cares:- 

Time to time remove thrive and died plants.

If terrarium is closed, take off the top lid at least once a month to air it out.

It should be kept in a light, but not direct sunlight, setting.

Terrariums normally last for a year or more. They can then be redesigned.


Terrarium has made significant contributions to landscape architecture. It's a glass container with a lid or without lid, that's a pleasant way to grow a collection of small plants.

 A terrarium, with careful care, can provide a humid environment that protects tender, tropical plants that are difficult to develop in the usually dry environment of homes. 

It can also help to start new plants under regulated conditions. 

The plants in their glass enclosures were decorative, and the concept was quickly adopted for home interior design.
