Begonias are typically grown as annuals and need to be stored indoors during winter until the return of warmer weather in spring. Here are some steps to follow for storing begonias after flowering:
- Stop watering the plants when the leaves start to turn yellow and allow them to dry out. All the leaves and stems will then start to turn yellow and die back.
- Once the foliage has faded or just after the first light frost, dig up the tubers and remove the stems and leaves down to the tuber. Spread begonia clumps on newspaper and leave them in a sunny area until thoroughly dry — about a week. Once they have sufficiently dried, cut away any remaining foliage and gently shake off excess soil.
- Place each tuber in a separate paper bag, and place them in a cool, dark place like a cardboard box for storage. Basements and garages are often good choices.
- For best results, you should cure (dry) begonia tubers before overwintering them. That way, theres less risk of them rotting or molding. First check to make sure the tubers are dry and then store them in a cool, dry place until spring.
By following these steps, you can store your begonias over winter and enjoy them year after year.
