When selecting a Begonia for your terrarium, consider the size of your terrarium and the lighting conditions it provides. Most Begonias prefer bright, indirect light and high humidity. Ensure that the terrarium has good ventilation to prevent excessive moisture buildup.

It’s important to regularly monitor and adjust watering to maintain slightly moist soil without allowing it to become waterlogged. Additionally, keep an eye out for pests like spider mites or mealybugs, as they can be common in terrarium environments.

Overall, Begonias especially Begonia ferny Borneo can bring beauty and variety to your terrarium setup while thriving in the humid conditions typically found inside.
