Begonia lovers, rejoice! While these vibrant flowers are often considered annuals, the truth is that can you overwinter begonia? Absolutely! With a little know-how and care, you can keep your beloved begonias thriving even when the temperatures drop. This guide will walk you through the process, revealing the secrets to successfully overwintering your begonia plants.
Understanding Begonia Types and Their Winter Needs
The first step in overwintering your begonia is to understand the specific species you have. Different types of begonias have varying degrees of cold tolerance.
- Tuberous Begonias: These beauties produce vibrant, large flowers and are often the star of summer gardens. They are generally more sensitive to cold and require a period of dormancy during the winter.
- Wax Begonias: With their glossy, waxy leaves and abundance of small flowers, wax begonias are popular choices for hanging baskets and containers. They are generally more tolerant of cooler temperatures than tuberous begonias, but still benefit from a bit of winter care.
- Rex Begonias: Known for their stunning foliage in a kaleidoscope of colors and patterns, Rex begonias are prized for their decorative value. They are generally more cold-hardy than tuberous and wax begonias, but still prefer warmer temperatures.
The Art of Bringing Your Begonia Indoors
Once the first frost threatens, it’s time to bring your begonias indoors. Choose a location that receives bright, indirect light and has temperatures between 55-65°F (13-18°C). Avoid placing them near drafts or heating vents, as these can dry out the air and stress the plants.
Pruning and Repotting for a Fresh Start
Before bringing your begonias inside, give them a light prune. Remove any dead or damaged leaves and stems. This encourages new growth and helps prevent diseases. If your begonias are rootbound, repot them into a slightly larger container with fresh potting mix.
Light and Watering: The Keys to Winter Survival
Light is crucial for overwintering begonias. They need at least six hours of bright, indirect light daily. Consider using grow lights if natural light is limited. Watering is another important aspect. Allow the top inch of soil to dry out between waterings, but don’t let the soil become completely dry.
Dormant Beauty: The Case of Tuberous Begonias
Tuberous begonias require a period of dormancy during the winter. After the first frost, cut back the stems and foliage. Gently lift the tubers from the soil, brush off excess dirt, and store them in a cool, dry location (around 50°F or 10°C). Place them in a paper bag or cardboard box filled with peat moss or vermiculite. Check on them occasionally to ensure they aren’t drying out.
The Art of Propagation: Creating New Begonias
Winter is a great time to propagate begonias. You can easily start new plants from cuttings or leaf cuttings. Simply take a 4-6 inch stem cutting or a leaf with a petiole (the stalk) and place it in a pot with moist potting mix. Cover the pot with a plastic bag or dome to create a humid environment. Within a few weeks, you should see roots forming.
Spring Awakening: Bringing Your Begonia Back to Life
As spring approaches, it’s time to revive your begonias. For tuberous begonias, gently replant the tubers in fresh potting mix. Water them sparingly until new growth appears. For other types of begonias, gradually increase watering and light exposure as the days lengthen.
A Farewell to Winter: Preparing for Outdoor Life
Once the threat of frost has passed, you can gradually acclimate your begonias to outdoor conditions. Start by placing them outdoors for a few hours each day, increasing the time gradually until they can spend the entire day outside.
Beyond the Basics: Additional Tips for Success
- Fertilize: During the winter months, fertilize your begonias sparingly with a balanced liquid fertilizer diluted to half strength.
- Humidity: Begonias thrive in humid environments. Consider using a humidifier or placing a tray of water near your plants.
- Pest Control: Regularly inspect your begonias for pests, such as aphids, mealybugs, or spider mites. Treat any infestations promptly.

Q: What are the best types of begonias for overwintering?
A: While all begonia types can be overwintered, tuberous begonias require a dormant period, while wax begonias and Rex begonias are generally more cold-tolerant.
Q: Can I overwinter begonias outdoors in a mild climate?
A: In mild climates, you may be able to overwinter begonias outdoors if they are protected from frost. However, it’s still a good idea to bring them indoors for the coldest months.
Q: Can I cut back my begonias in the winter?
