15 Best Plants for a Closed Terrarium that are Ideal for a Beginner

Closed Plants Terrarium

Plants that are ideal for a closed terrarium are moisture-loving or humidity-loving plants which require a constantly moist atmosphere to thrive.

A closed terrarium or bottle garden is always more humid than the surrounding room atmosphere which makes it an ideal environment to grow the delicate moisture-loving plants

A terrarium is one of the common methods by which you can display your indoor plants.

What is a Closed Terrarium?

A closed terrarium is a glass or transparent container inside which plants are grown. The top is naturally restricted or covered with a transparent material.

The closed terrarium completely surrounds the plants and as a result keeps off the plant-killing draughts.

The air within a closed terrarium is always moister than the room atmosphere which makes it perfect for growing the delicate plants which may require high humidity and protection from draughts.

Some containers that are ideal for a closed terrarium include a fish tank, a large bottle or even a large mixing bowl.

The only requirement is to have transparent sides and a restricted opening or an opening that can be covered with a transparent material. There are many types of beautiful terrariums to choose from.

How to Select Plants for a Closed Terrarium

While selecting plants for a closed terrarium, select a variety of plants that vary in height, growth habits and texture in order to have an interesting landscape.

Select plants that have close or similar light requirements inorder to make it easier to maintain your plants thriving.

Avoid flowering plants as flowering plants have different light requirements through out the year.

If you select flowering plants for your closed terrarium, it will be difficult to remove dead flowers when they are spent.

Most flowers also require good air circulation in order to prevent powdery mildew and fungal diseases, a situation that is not feasible in a closed terrarium.

How to Prepare Plants for a Closed Terrarium

To prepare the plants for the terrarium; pinch off the growing tips and prune tall and spreading types to minimize their size. Remove dead and yellow foliage.

Check the plants for pest and disease infestations; do not use any infested plant as using them will introduce these infestations in the terrarium environment and they will be difficult to control.

How to Care for a Closed Terrarium

How to water plants in a closed terrarium

Ensure the soil is moist at all times; water sparingly. In most cases if the terrarium is well covered, watering will not be necessary as there is minimal evaporation and the plants form their own ecosystem inside the terrarium.

If there is condensation on the inside of the glass soon after planting, open the terrarium to allow excess moisture to evaporate.

Light for plants in a closed terrarium

Place the terrarium in a bright spot but away from direct sunshine to avoid cooking the plants. Plants in a terrarium can also thrive under artificial light.
