How to Grow Begonia in a Terrarium

What Types of Begonia Are Good for a Terrarium

There are many types of begonias, and not all are suitable for terrariums. From my experiences, I’ve made a list of some types of begonias that are well-suited for life in a terrarium:

  1. Begonia Rex

This is one of the most popular types of terrariums. Begonia Rex, also known as the King Begonia, is known for its colorful and patterned leaves. They’re small, making them perfect for terrarium life.

  1. Begonia Bowerae

 Also known as the Eyelash Begonia, this variety has dark, small, and round leaves with bright green edges resembling eyelashes. This begonia thrives in terrariums due to its preference for high humidity.

  1. Begonia Amphioxus 

This begonia species is native to Borneo and has a unique leaf shape with bright spots. It loves humidity and does well in terrarium conditions.

  1. Begonia Pavonina

Known as the Peacock Begonia, this species has shiny, iridescent leaves that change color depending on the angle of light. It’s another variety that loves high humidity, making it ideal for a terrarium.

  1. Begonia Thelmae

This is a small variety with lovely dark green leaves and bright white spots. It’s another humidity-loving species that thrive in a terrarium.

Benefits of Growing Begonia in a Terrarium

Begonias and terrariums are a match made in horticultural heaven. The terrarium’s enclosed environment mimics the begonia’s natural humid habitats, helping it thrive. The glass enclosure also allows for optimal light exposure, which is vital for the growth of begonias.

Step-by-Step Guide to Growing Begonia in a Terrarium

Let’s dive into how you can create your begonia-filled terrarium.

1. Choosing the Right Terrarium

You’ll need a large glass container to accommodate your begonia without cramping it.

2. Selecting the Perfect Begonia

Not all begonias are ideal for terrariums. Smaller varieties, like the Begonia rex, are more suitable due to their size and preference for high humidity.

3. Setting Up Your Terrarium

Start by layering pebbles at the bottom of the terrarium for drainage, followed by activated charcoal to prevent mold growth. Then, add a layer of potting soil rich in organic matter.

4. Planting Your Begonia

Place the begonia in the soil, ensuring it’s not too deep. The crown of the plant should sit at the soil’s surface.

5. Maintaining Your Terrarium


Begonias need moist, not waterlogged, soil. A spray bottle is perfect for watering your begonia terrarium, ensuring a light misting rather than a drenching.


Begonias thrive in bright, indirect light. Avoid placing your terrarium in direct sunlight to prevent the risk of scorching the plant.


Maintain a temperature between 60-80°F. Begonias prefer a warmer climate but can tolerate slightly cooler temperatures if they don’t drop too low.


Pruning encourages bushier growth and helps control the size of your begonia. Regularly check for any dead or dying leaves and remove them promptly.

Troubleshooting Common Problems

Despite your best efforts, you might need help to grow your begonia in a terrarium. Yellow leaves could indicate overwatering, while brown leaf tips might suggest low humidity. Adjusting your care routine accordingly can often rectify these problems.

Additional Tips for Growing Begonia in a Terrarium

Successful gardening requires a blend of knowledge, skill, and patience. Here are some tips to help you master growing begonias in a terrarium.

Fertilizing Your Begonia

Begonias are not heavy feeders, but they occasionally appreciate a little boost. Apply a water-soluble houseplant fertilizer at quarter strength every month during the growing season. Be sure not to over-fertilize, as this can cause more harm than good.

Managing Pests

Begonias can sometimes attract pests like mealybugs and spider mites. If you spot any pests, isolate your plant to prevent them from spreading. Treat the plant with an insecticidal soap or a mixture of water and mild dish soap.

Refreshing the Terrarium

Over time, your terrarium needs refreshing. If you see mold, remove it immediately. If the soil is depleted, add fresh soil. And if the glass becomes dirty, clean it with a damp cloth.

Enjoying Your Begonia Terrarium

Remember, growing a begonia in a terrarium is meant to be enjoyable. Don’t stress over perfection. Appreciate the process and the unique beauty of your plant.
