Don’t Toss Those Begonia Bulbs! Discover if You Can Keep Them for Next Year

The vibrant colors and delicate beauty of begonias make them a popular choice for gardens and containers. But, can you keep begonia bulbs for next year, ensuring a return of their stunning blooms? The answer is a resounding yes, but it requires some knowledge and care. This guide will delve into the fascinating world of begonia bulbs, exploring the best practices for storing them and re-planting them for another season of vibrant color.

Understanding Begonia Bulbs: The Key to Re-Planting

While often called bulbs, begonias actually produce tubers, which are thickened, underground stems that store nutrients and act as a source for new growth. These tubers are the key to successfully keeping begonias for next year. Unlike true bulbs, which are often dormant, begonia tubers remain active even during winter, requiring specific storage conditions to thrive.

The Art of Harvesting Begonia Tubers: A Step-by-Step Guide

The first step toward ensuring vibrant blooms next year is to harvest the tubers correctly. Here’s a simple guide:

1. Timing is Key: Begin harvesting tubers in the fall after the first frost or when the foliage starts to die back. This typically occurs in late September or early October.
2. Gentle Digging: Carefully dig around the base of the plant, avoiding damage to the tubers.
3. Cleaning and Drying: Remove any excess soil and let the tubers air dry in a cool, shaded location for a few days. This allows the skin to harden and prevents rot.
4. Inspecting for Damage: Check for any signs of disease or damage. Discard any unhealthy tubers.

Storing Begonia Tubers: Creating the Perfect Winter Haven

Once you’ve harvested the tubers, it’s essential to provide them with the ideal storage conditions. Here’s how to create a winter haven for your begonia tubers:

1. Choose a Cool and Dry Location: The perfect storage environment is cool, dry, and well-ventilated. A basement, garage, or even a refrigerator can be suitable spots.
2. Use a Suitable Container: Store the tubers in a breathable container, such as a cardboard box or a mesh bag. Avoid airtight containers that can encourage moisture buildup and rot.
3. Layer with Peat Moss or Vermiculite: To prevent drying, surround the tubers with peat moss or vermiculite. These materials help maintain a consistent moisture level.
4. Maintain a Consistent Temperature: Aim for a storage temperature between 45°F and 55°F (7°C to 13°C). This range allows the tubers to remain dormant but prevents them from freezing.
5. Regular Inspections: Check the tubers periodically for signs of rot or mold. If you notice any issues, remove the affected tubers immediately.

Re-Planting Begonia Tubers: Bringing Back the Blooms

As spring approaches, it’s time to re-plant your stored begonia tubers and watch them burst back to life.

1. Prepare the Soil: Choose a well-draining potting mix or garden soil amended with compost.
2. Planting Depth: Plant the tubers with the growing point facing upwards, about 1-2 inches deep.
3. Watering and Light: Water gently after planting and provide indirect sunlight.
4. Patience is Key: It may take a few weeks for the tubers to sprout and begin producing leaves.
5. Fertilizing: Once the plants start growing, fertilize regularly with a balanced fertilizer to encourage healthy growth and blooming.

Begonia Bulb Care: A Year-Round Commitment

While storing and re-planting begonia tubers can seem like a lot of work, the rewards are well worth the effort. Here are some additional tips for ensuring the success of your begonia bulbs:

1. Choose the Right Varieties: Some begonia varieties, like tuberous begonias, are known for their excellent storage capabilities.
2. Avoid Overwatering: Begonia tubers are susceptible to rot, so avoid overwatering. Allow the soil to dry slightly between waterings.
3. Provide Adequate Light: Begonias thrive in bright, indirect light. Avoid exposing them to direct sunlight, which can scorch their leaves.
4. Watch for Pests and Diseases: Be vigilant for pests like aphids and mealybugs, and common diseases like botrytis blight. Address any issues promptly to prevent further damage.

A Final Word: Beyond the Bulbs

While this guide focuses on the storage and re-planting of begonia tubers, it’s important to remember that begonias can also be propagated from seeds or cuttings. This can be a fun and rewarding way to expand your begonia collection and enjoy their vibrant beauty year after year.

Answers to Your Questions

1. Can I store begonia tubers in a refrigerator?

Yes, you can store begonia tubers in a refrigerator, but it’s crucial to choose a crisper drawer with a high humidity setting. Avoid placing them near fruits and vegetables that emit ethylene gas, which can harm the tubers.

2. How long can I store begonia tubers?

Begonia tubers can generally be stored for 6-12 months. However, their viability can decrease over time, so it’s best to re-plant them within a year for optimal results.

3. What happens if I forget to store my begonia tubers?

If you forget to store your begonia tubers, they may not survive the winter. However, if they are in a frost-free location with adequate protection, they may still sprout in the spring.

4. Can I grow begonia tubers in a pot?

Yes, begonia tubers can be grown successfully in pots. Choose a pot that is slightly larger than the tuber and has drainage holes.

5. How often should I fertilize my begonia tubers?

Fertilize your begonia tubers every 2-3 weeks during the growing season with a balanced fertilizer. Avoid fertilizing during the dormant period.

By following these tips and tricks, you can enjoy the vibrant beauty of begonias year after year. With a little care and attention, your begonia bulbs will continue to bloom, adding a touch of color and cheer to your garden and home.
