Can begonias stay outside in winter?

As a gardening and landscaping expert, I can provide you with some insights on whether begonias can stay outside in winter. Generally, both types of begonias, annual or bedding begonias, and tuberose begonias are cold sensitive and it is recommended to bring them indoors over winter in most parts of the country.

Cold temperatures can be detrimental to begonias, causing the plants to die or go into dormancy. In regions with mild winters, where temperatures rarely drop below freezing, it may be possible to leave begonias outside. However, it is essential to monitor the weather conditions and take precautions to protect the plants.

If you choose to leave your begonias outside during winter, consider the following tips:

1. Mulching: Apply a layer of organic mulch around the base of the plants. This will help insulate the soil and provide some protection against freezing temperatures. Mulch can be made from materials such as straw, compost, or shredded leaves.

2. Protective covers: Use frost blankets or cloths to cover the begonias during cold snaps or frosty nights. These covers help trap heat and prevent frost damage. Remember to uncover the plants during the day to allow sunlight and airflow.

3. Sheltered locations: Place the begonias in a sheltered spot, such as against a south-facing wall or under an overhang. These locations can provide some protection from harsh winds and cold temperatures.

4. Potted begonias: If you have begonias in pots, it is easier to bring them indoors for winter. Before moving them indoors, inspect the plants for any pests or diseases and treat if necessary. Place the pots in a well-lit area, away from drafts and extreme temperatures.

However, it is important to note that begonias are generally better suited for indoor cultivation during winter. This is especially true in regions with colder climates, where frost and freezing temperatures are more common.

For tuberose begonias, which are grown from tubers, it is crucial to properly store the tubers over winter. Here is a step-by-step guide for begonia tuber storage:

1. Digging up the tubers: Once the foliage has died back after the first frost, carefully dig up the tubers from the ground or containers. Gently remove excess soil without damaging the tubers.

2. Drying: Allow the tubers to dry in a well-ventilated area for a few days. This helps prevent fungal or bacterial infections during storage.

3. Cleaning: Remove any remaining foliage or debris from the tubers. Inspect them for any signs of rot or disease. Discard any damaged or unhealthy tubers.

4. Storage medium: Choose a storage medium such as peat moss, vermiculite, or dry sand. Place a layer of the storage medium in a container, then add the tubers, ensuring they are not touching each other. Cover the tubers with more storage medium, but make sure the tubers are not buried too deeply.

5. Storage conditions: Store the tubers in a cool, dry, and dark location. The ideal temperature for begonia tuber storage is around 45-55°F (7-13°C). Check the tubers periodically during storage to ensure they are not drying out or rotting.

By following these steps, you can successfully store begonia tubers over winter and replant them in the spring for continued growth and beauty in your garden.

While it may be possible to leave begonias outside in mild winter regions, it is generally recommended to bring them indoors for winter. Tuberose begonias should be dug up and properly stored to ensure their survival and regrowth in the following season. Remember to always consider the specific climatic conditions and adapt your approach accordingly to protect your begonias during the colder months.
