Did You Know?
1. Non-tuberous begonias (such as fibrous-rooted begonias) can actually survive a light frost if proper precautions are taken.
2. Begonias have a fascinating defense mechanism to survive frost; their cells produce higher concentrations of sugars, acting as a natural antifreeze to prevent cellular damage.
3. Interestingly, begonias native to higher altitudes have a greater ability to withstand frost than those from lower altitudes, as they have adapted to extreme weather conditions over time.
4. Certain begonia species can tolerate temperatures below freezing for short periods if they are well mulched or protected by a layer of straw.
5. To increase the chances of begonias surviving frost, they can be covered with a frost cloth or moved to a more sheltered location, such as near a south-facing wall, in order to provide extra insulation and protection against freezing temperatures.
Overwintering Tuberose Begonias: Tips For Success
Tuberose begonias, known for their beautiful blooms and delicate leaves, are extremely sensitive to cold temperatures. As the winter months approach, it is crucial to take necessary steps to protect these plants and ensure their survival until the warmer seasons return.
To overwinter tuberose begonias, it is advised to reduce watering in late summer. This allows the plants to slowly go dormant and prepares them for the upcoming frosty conditions. Once the foliage begins to yellow or the first fall frost occurs, it is time to dig up the tubers.
After carefully digging up the tubers, it is important to cut back the stems and allow them to dry indoors. This drying process helps to prevent mold or rot during storage. Once completely dry, the tubers can be stored in vermiculite or peat moss. A cool and dark place, ideally at temperatures between 40-50 degrees Fahrenheit, is suitable for storage. This ensures the tubers remain dormant and are not exposed to extreme temperature fluctuations that could potentially harm them.
Protecting Tuberous Begonias And Dahlias From Frost
Tuberous begonias and dahlias are susceptible to frost damage and should be brought indoors for the winter season. By taking the necessary precautions, these plants can be preserved and thrive once the frost-free period returns.
Storing tuberous begonias and dahlias involves removing them from the ground or containers. Before storing, it is recommended to cut back the stems to ensure easy handling and storage. Proper drying is important to prevent rotting or disease development during the dormant period.
When it comes to storage options, you can either keep the tubers in a cool and dry location or pack them in slightly damp perlite and peat moss to maintain moisture levels. Both methods have proven successful, and the choice ultimately depends on personal preference and available storage conditions.

Keeping Annual Bedding Begonias Indoors: A Guide
Annual bedding begonias are a great choice for colder temperatures, although they are still not frost-resistant. To ensure their survival and continuous growth, it is recommended to bring these plants indoors before the nights start getting colder (drops into the 40s).
When selecting a suitable location for indoor begonias, it is important to find a spot that offers enough light without exposing the plants to harsh direct sunlight. An ideal option would be a somewhat-sunny windowsill or any area with moderate light conditions during the winter months.
To promote the health and vitality of begonias, it is crucial to use containers with good drainage. A mixture of compost and potting soil is highly recommended as it provides the necessary nutrients and moisture retention for the plants. Avoid using garden soil, as it may contain pests or diseases that can harm the begonias.

Essential Tips For Indoor Begonias: Soil And Containers
Indoor begonias, regardless of the variety, require specific care and attention to thrive during the winter months. The choice of soil and containers significantly impacts the plant’s growth and overall health.
When it comes to indoor begonias, it is crucial to use a mixture of compost and potting soil. This combination provides the necessary nutrients and proper drainage to prevent waterlogging, which can lead to root rot. Good drainage is essential for the roots to breathe and absorb nutrients effectively.
In terms of containers, it is best to opt for those with good drainage holes. This ensures excess water can escape and prevents the accumulation of stagnant water that could lead to root rot and other fungal diseases. Additionally, choosing the right-sized container is important to accommodate the root system and allow room for growth.
Preserving Begonias For Winter: Different Approaches
There are different approaches to preserving begonias for the winter season, each with its advantages and disadvantages. It ultimately depends on factors such as available space, desired outcome, and personal preferences.
One approach is to cut the begonias back and bring them indoors in pots. This method allows for constant monitoring and care, making it easier to address any potential issues promptly. However, it requires sufficient space indoors and may not be feasible for those with limited room.
Another approach is to keep the begonias bare root and hang them. This method allows the plants to go dormant naturally while saving valuable indoor space. However, it requires careful handling and may be more challenging for beginners.
Overall, the key to preserving begonias for winter lies in understanding the specific needs of each variety, including tuberose, tuberous, and bedding begonias.
Some additional tips to consider when preserving begonias for winter are:
- Tuberose begonias: Store them in a cool and dry location, away from direct sunlight.
- Tuberous begonias: Dig up the tubers, remove excess soil, and allow them to dry before packing them in a moisture-free medium.
