Begonia Rex is a stunning plant with colorful and patterned foliage that can be grown successfully in a terrarium. Here are some guidelines for keeping your Begonia Rex healthy and happy in a terrarium:
Choose the right terrarium: Make sure the terrarium is large enough to accommodate your Begonia Rex, but not so large that it will take up too much space. A closed terrarium is recommended, as it will help to maintain high humidity levels.
Use the right substrate: Begonia Rex prefers a well-draining soil mix that is rich in organic matter. Choose a substrate that is specifically designed for terrariums or make your own mix with perlite, peat moss, and sphagnum moss.
Provide proper lighting: Begonia Rex prefers bright, indirect light, so make sure your terrarium is placed in a location that gets plenty of natural light or provide artificial lighting if necessary. Avoid direct sunlight, as this can scorch the leaves.
Maintain proper humidity levels: Begonia Rex prefers higher humidity levels, so mist the plant regularly and consider using a humidifier if necessary. Make sure to monitor the humidity levels inside the terrarium to prevent mold growth.
Water properly: Water your Begonia Rex when the top inch of soil feels dry to the touch, but be careful not to overwater, as this can lead to root rot. Use a spray bottle or watering can to water the plant, and make sure any excess water can drain away.
Fertilize as needed: Begonia Rex can benefit from regular fertilization, but be careful not to over-fertilize, as this can lead to leaf burn. Use a balanced fertilizer diluted to half strength every 2-3 weeks during the growing season (spring and summer).
Prune as needed: Begonia Rex can be pruned to control its size and shape. You can also pinch off the tips of new growth to encourage bushier growth.
By following these guidelines, you can keep your Begonia Rex healthy and thriving in a terrarium.
