As the days grow shorter and the nights grow colder, it’s time to prepare our beloved begonia plants for their winter slumber. Storing begonias over winter is crucial for their survival and ensuring a vibrant bloom come spring. This comprehensive guide will provide you with step-by-step instructions and expert tips on how to store begonia plants over winter, ensuring their well-being until the warm weather returns.
Step 1: Choose the Right Location
The ideal storage location for begonias is a cool, dark, and dry place. A basement, garage, or unheated attic can provide suitable conditions. The temperature should remain between 45-55°F (7-13°C) throughout the winter. Avoid storing begonias in areas that are too warm or humid, as this can promote rot and disease.
Step 2: Prepare the Plants
Before storing begonias, it’s essential to prepare them for the dormant period.
- Reduce Watering: Gradually reduce watering frequency in the weeks leading up to storage. Allow the soil to dry out slightly between waterings.
- Fertilize Lightly: Fertilize begonias with a balanced fertilizer one last time before storage. This will provide them with nutrients to sustain them through the winter.
- Trim Back Foliage: Remove any dead or yellowing leaves and stems. Cut back the remaining foliage by about half to reduce moisture loss.
Step 3: Dig Up Tuberous Begonias
Tuberous begonias require special care over winter.
- Dig Up Tubers: After the first frost, dig up tuberous begonia plants. Knock off excess soil and allow the tubers to dry in a cool, shady spot for several days.
- Store Tubers: Place the tubers in a box or basket filled with dry peat moss or vermiculite. Store them in a cool, dark place with good air circulation.
Step 4: Store Rex Begonias
Rex begonias are known for their stunning foliage.
- Cut Back Stems: Cut back the stems of rex begonias to about 2 inches above the soil line.
- Store in Pots: Keep rex begonias in their pots and store them in a cool, dark location.
- Water Sparingly: Water rex begonias sparingly throughout the winter, just enough to keep the soil slightly moist.
Step 5: Store Rhizomatous Begonias
Rhizomatous begonias spread through underground stems called rhizomes.
- Divide Rhizomes: Divide the rhizomes into smaller sections, ensuring each section has a few roots.
- Store Rhizomes: Place the rhizome sections in a box or basket filled with dry peat moss or vermiculite. Store them in a cool, dark place with good air circulation.
Step 6: Store Fibrous-Rooted Begonias
Fibrous-rooted begonias have shallow root systems.
- Cut Back Stems: Cut back the stems of fibrous-rooted begonias to about 4-6 inches above the soil line.
- Store in Pots: Keep fibrous-rooted begonias in their pots and store them in a cool, dark location.
- Water Occasionally: Water fibrous-rooted begonias occasionally throughout the winter, just enough to keep the soil slightly moist.
Tips for Successful Storage
- Check Regularly: Inspect stored begonias regularly for signs of rot or disease. Remove any affected leaves or stems immediately.
- Control Humidity: Ensure the storage area has good air circulation to prevent excessive humidity.
- Avoid Overwatering: Overwatering can lead to rot. Water begonias sparingly throughout the winter.
- Monitor Temperature: Keep the storage temperature between 45-55°F (7-13°C). Fluctuating temperatures can damage begonias.
- Label Plants: Label stored begonias with their variety and storage date for easy identification in spring.
Summary: Ensuring a Thriving Spring Bloom
By following these comprehensive steps and adhering to the expert tips provided, you can successfully store your begonia plants over winter. With proper care and attention, your begonias will emerge from their winter slumber in spring, ready to burst forth with vibrant blooms and lush foliage.
