Not everyone has access to a garden. If you live in an apartment building or an urban area, you may not have the outdoor space to cultivate your green thumb. Terrariums are self-sustaining mini gardens that you can enjoy in the comfort of your own home. These glass or plastic containers hold soil and plants while trapping moisture to create an enclosed growing system. Your inner botanist can experiment moisture-loving plants like tropical orchids, or you can try your hand at Insta-worthy succulents in an open terrarium.
Terrariums are an excellent addition to your home décor and come in an exciting variety of shapes and sizes. Some can hold multiple plant species, allowing you to get creative with miniature landscaping.
The predecessor of the terrarium was an unattended glass jar. A Victorian physician experimenting with moths accidently discovered that he could grow rare ferns inside a sealed glass jar. This birthed stylized glass structures, known as Wardian cases, that became a popular fixture of Victorian parlors and sitting rooms. Today, the Wardian case is just one of the terrarium types you can choose from.
Wardian case: These classic, antique-style cases are modeled like mini-conservatories or greenhouses with hinged roofs that lift open. They tend to be the largest and priciest terrariums on the market.
Glass cloche: This bell-shaped cover also dates back to the Victorian era. Used indoors, it’s an attractive enclosure that can showcase moisture-loving plants. If placed over a dish with layers of gravel, charcoal, moss, and potting medium, it can create its own rain cycle.
Closed terrarium: This sealable glass container, often rectangular in shape, holds a special soil mix and plants to replicate the environment of the tropics. The glass shelter traps moisture, and the circulation of water creates a humid environment for moisture-loving plants like orchids, mosses, and ferns.
Open terrariums: Also made of glass, open terrariums have an opening that allows for the circulation of air. These are better suited for air plants, cacti, and succulents, which need less moisture to thrive. Open terrariums tend to be globe-shaped or geometric in design.
Hanging terrarium: Shaped as globes, tear drops, pyramids, or other geometric structures, many hanging terrariums are suspended from ceilings with twine or fishing wire. There are also some hanging terrarium options that hang from mountable hooks on the wall.
Vivarium: A closed terrarium with ventilation, the vivarium is designed to house reptiles and amphibians in a plant-rich, semi-natural environment.
Some hanging terrariums come a metal stand that can hang one or two globe-styled terrariums. These sturdy stands can be placed on the floor, on a table, or on a shelf. Choosing a terrarium with a stand saves you the fuss of figuring out how to hang it from your ceiling.
The standard terrarium is rectangular and shaped much like an aquarium, but there are an array of other three-dimensional shapes to choose from. A common shape for open and hanging terrariums is a globe. You will also see terrariums in pyramid-like structures and other geometric shapes. Zany, unique designs — like lightbulb or tea kettle terrariums — can be found with some internet searching.
The majority of terrariums do not come with plants or soil mix. However, there are terrarium kits available for separate purchase. A terrarium kit may include gravel, rocks and/or pebbles, potting soil, moss, vermiculite, and activated charcoal. Some are specific to plant type, like succulents.
Most terrariums are designed for adult use and aesthetics. The glass housing is breakable and best handled by adults. However, building a terrarium with your favorite child is a fun, educational pastime that can be enjoyed with a terrarium kit designed specifically for kids. These kits come with a plastic lidded jar, soil mix, and seeds. Some also come with miniature toys and LED lighting in the lid.
Kids’ terrariums and hanging terrariums, including ones with stands, tend to be the most affordable options. These generally cost less than $20. Open terrariums that rest on a table or other flat surface cost a little more, from $20 to $35. Closed terrariums, including vivariums, are the priciest options. Most of these range from $50 to $100. Wardian case terrariums, however, can exceed $200.
If you want to grow succulents, be aware that a closed terrarium requires a different soil mix than an open terrarium. For a closed terrarium, layer the following ingredients from the bottom up: pebbles, activated charcoal, moss, and potting soil appropriate for your plant species.
If you’re looking for a way to house moisture-loving plants, choose a sealed terrarium that won’t leak. Higher-quality terrariums tend to be more airtight and waterproof. If you’re just growing succulents, cacti, or air plants, however, this isn’t a huge concern.
Plan your miniature landscape ahead of time. When choosing plants for your terrarium, select species that won’t grow too wild and outgrow the container. For some people, the planning is half the fun.
Let your creativity flow. If you’re feeling crafty, consider adding miniature figurines to create a themed terrarium, such as a fairy garden or a woodland scene.

Q. Do I need to water my terrarium?
A. Even though closed terrariums provide their own moisture, they do need extra water occasionally — roughly once a month. As long as you see condensation on the walls of your closed terrarium, however, you don’t need to add water.
For open terrariums housing succulents and other low-moisture plants, only add water when the soil is dry. Instead of pouring water directly onto the soil, we recommend using a spray bottle with water to dampen the soil around each plant. Roughly once every ten days is a solid rule of thumb when watering succulents.
Q. What is activated charcoal used for in terrariums? Do I need it?
A. Because terrariums do not contain drainage holes like you might find in the bottom of a planter, a layer of activated (or horticulture) charcoal helps soak up excess water that could otherwise rot your plants’ roots. This layer is typically placed over drainage gravel or pebbles in the base of the terrarium. Charcoal also helps absorb toxins and eliminates odor caused by mold or mildew.
Alternatively, you could use a layer of live moss to absorb excess water and odor. Another option is to open your (closed) terrarium for a few hours each day to help odors dissipate. Be advised, however, that you’d have to water more often due to the moisture loss.
Q. What kinds of plants are best to grow in a terrarium?
A. Plants that are petite are best. Consider the size of your terrarium; it’s best to select plants that won’t touch the walls. If you’re mixing species, we recommend picking plants with similar light and watering needs. A few plant species that you might consider for a closed terrarium that don’t need much sunlight are spider ferns, peperomias, moss, and violets. For a hanging terrarium, air plants are very low-maintenance and don’t even require soil! They do, however, need adequate light.
