Understanding Begonia Hardiness
Before delving into winter care, it’s important to understand the hardiness of begonias. Most begonias are classified as tender perennials, meaning they cannot withstand freezing temperatures. Therefore, they require special care during the winter months to prevent damage or death.
Methods for Winterizing Begonias
1. Indoor Overwintering
Materials:
- Pots or containers
- Potting mix
- Water
- Bright, indirect light
Steps:
1. Dig up begonias before the first frost.
2. Remove excess soil and trim back stems to 4-6 inches.
3. Repot begonias in a well-draining potting mix.
4. Water thoroughly and place in a bright, indirect light location.
5. Maintain temperatures between 60-70°F (16-21°C).
2. Outdoor Overwintering in Mild Climates
Materials:
- Mulch
- Frost cloth or burlap
Steps:
1. Mulch heavily around the base of begonias with organic matter such as shredded leaves or compost.
2. Cover begonias with frost cloth or burlap when temperatures drop below 50°F (10°C).
3. Remove the cover during the day when temperatures rise.
3. Overwintering Tuberous Begonias
Materials:
- Newspaper or paper bags
- Sand or vermiculite
- Cool, dark storage location
Steps:
1. Dig up begonias after the first frost and cut back foliage.
2. Clean tubers and remove any damaged or diseased ones.
3. Wrap tubers in newspaper or paper bags.
4. Place tubers in a container filled with sand or vermiculite.
5. Store in a cool, dark location with temperatures between 40-50°F (4-10°C).
Watering and Fertilizing Over Winter
Watering:
- Water sparingly during the winter months.
- Allow the soil to dry out slightly between waterings.
- Avoid overwatering, as it can lead to root rot.
Fertilizing:
- Fertilize begonias lightly every 4-6 weeks during the winter.
- Use a balanced fertilizer diluted to half strength.
- Stop fertilizing 6 weeks before bringing begonias back outdoors.
Monitoring and Troubleshooting
- Check begonias regularly for pests or diseases.
- Treat any issues promptly.
- If begonias start to wilt or lose leaves, it may indicate a problem with watering or temperature.
Preparing for Spring
- Gradually increase watering and fertilizing frequency as spring approaches.
- Harden off begonias by exposing them to outdoor temperatures for a few hours each day.
- Transplant begonias back outdoors after the last frost.
Final Note: Ensuring a Vibrant Winter and Spring
By following these steps, you can successfully save begonia plants over winter and enjoy their beauty throughout the year. Remember to monitor them regularly and adjust care as needed. With proper winter care, your begonias will thrive and reward you with stunning blooms come spring.
