How to Save Begonia for Next Year: Expert Tips on Overwintering Begonias
What To Know
- Remove any remaining soil from the tuber, and let it dry in a cool, dark place for a few days.
- Once the tuber is completely dry, store it in a cool, dry, and dark place.
- Place the cutting in a pot filled with moist potting mix, and cover it with a plastic bag to create a humid environment.
The vibrant colors and delicate beauty of begonias make them a beloved addition to any garden. But what happens when the weather turns cold and the blooms fade? Do you have to say goodbye to your cherished begonias until next spring? Not necessarily! This guide will walk you through the steps on how to save begonia for next year, ensuring you get to enjoy their stunning beauty season after season.
Understanding Begonia Types: The Key to Successful Overwintering
The first step in saving your begonias is understanding their different types. Begonias are broadly classified into two main categories:
- Tuberous Begonias: These are the most popular type for their large, showy blooms. They have fleshy tubers that store energy for the next growing season.
- Fibrous-rooted Begonias: These include wax begonias, rex begonias, and other varieties. They have a fibrous root system and don’t form tubers.
The method for overwintering begonias varies depending on their type. Let’s explore each method in detail.
Overwintering Tuberous Begonias: Bringing Back the Blooms
Tuberous begonias are the most rewarding to overwinter, as they can be stored and replanted the following year. Here’s how:
1. Time It Right: As the weather cools down and the first frost approaches, it’s time to dig up your tuberous begonias.
2. Careful Excavation: Gently dig around the base of the plant, being careful not to damage the tuber. Lift the entire plant out of the ground.
3. Cleaning and Drying: Remove any remaining soil from the tuber, and let it dry in a cool, dark place for a few days. This allows the tuber to heal and prevents rotting.
4. Storage Solution: Once the tuber is completely dry, store it in a cool, dry, and dark place. A paper bag or cardboard box filled with peat moss, vermiculite, or dry sand will provide ideal conditions.
5. Spring Revival: In early spring, when the danger of frost has passed, you can replant your tubers. Choose a sunny spot in your garden with well-draining soil. Bury the tuber about 2-3 inches deep, with the “eyes” (growth points) facing upwards.
Overwintering Fibrous-rooted Begonias: A Different Approach
While tuberous begonias can be stored for the winter, fibrous-rooted begonias require a different approach. Here’s how to keep them thriving:
1. Indoor Sanctuary: Move your fibrous-rooted begonias indoors before the first frost. Choose a bright spot with indirect sunlight, as direct sunlight can scorch their leaves.
2. Temperature Control: Maintain a cool temperature between 55-65°F (13-18°C) during the winter months. Avoid placing them near drafts or heating vents.
3. Water Sparingly: Reduce watering during the winter, as begonias will be dormant. Let the soil dry out slightly between waterings.
4. Spring Rejuvenation: As spring approaches, gradually increase watering and fertilize to encourage new growth. You can also repot your begonias into fresh potting mix.
Troubleshooting Common Issues: Keeping Your Begonias Healthy
While overwintering begonias is relatively straightforward, there are some common issues to watch out for:
- Rotting: Overwatering or storing tubers in damp conditions can lead to rotting. Inspect tubers regularly for signs of rot, and discard any affected parts.
- Pests: Be vigilant against pests like aphids, mealybugs, and spider mites. Treat any infestations promptly with an insecticidal soap or neem oil.
- Disease: Fungal diseases like botrytis can affect begonias. Ensure good air circulation and avoid overcrowding to prevent disease.
Begonia Propagation: Expanding Your Garden’s Beauty
If you’re looking to increase your begonia collection, propagation is a great option. Here are two simple methods:
- Leaf Cuttings: Cut a healthy leaf from your begonia, leaving about 1 inch of stem attached. Place the cutting in a pot filled with moist potting mix, and cover it with a plastic bag to create a humid environment. New plants will sprout from the leaf veins.
- Stem Cuttings: Take a 2-3 inch stem cutting from your begonia, removing the leaves from the bottom inch. Dip the cut end in rooting hormone, and insert it into a pot filled with rooting mix. Keep the soil moist and provide indirect sunlight.
Begonia Care: Ensuring Continued Blooms
Once your begonias are established, proper care is essential for continued blooms. Here are some key tips:
- Sunlight: Begonias thrive in bright, indirect light. They can tolerate some direct sun, but avoid exposing them to harsh midday sun.
- Watering: Water your begonias regularly, keeping the soil consistently moist but not soggy. Allow the top inch of soil to dry out between waterings.
- Fertilization: Feed your begonias with a balanced liquid fertilizer every 2-3 weeks during the growing season.
- Deadheading: Remove spent blooms to encourage further flowering.
Beyond the Basics: Exploring More Begonia Varieties
The world of begonias is vast and diverse. Beyond the traditional tuberous and fibrous-rooted varieties, there are countless other fascinating begonias to discover.
- Rex Begonias: These begonias are prized for their stunningly patterned leaves, which come in a wide range of colors and textures.
- Wax Begonias: These are compact and easy-to-grow begonias with bright, colorful blooms.
- Cane Begonias: These begonias are known for their tall, upright stems and cascading blooms.
A Legacy of Blooms: Enjoying Your Begonias for Years to Come
By following these simple tips, you can ensure that your begonias thrive for years to come. Whether you’re a seasoned gardener or just starting out, the beauty and versatility of begonias make them a rewarding addition to any garden.
Popular Questions
Q: Can I overwinter begonias outdoors in a mild climate?
A: If you live in a region with mild winters and no frost, you may be able to overwinter begonias outdoors. However, it’s best to provide some protection from cold winds and heavy rain.
Q: What if my begonia tuber doesn‘t sprout in the spring?
A: If your begonia tuber doesn‘t sprout after a few weeks, it may be dormant or damaged. Try gently pressing on the tuber to check for firmness. If it feels soft or mushy, it’s likely rotten.
Q: Can I divide begonia tubers?
A: Yes, you can divide begonia tubers to create new plants. Simply cut the tuber into sections, ensuring each section has at least one “eye.” Allow the cut surfaces to dry for a few days before planting.
Q: How long can I store begonia tubers?
A: Begonia tubers can be stored for several years, as long as they are kept in a cool, dry, and dark place. However, they may become less vigorous over time.
Q: What is the best way to fertilize begonias?
A: A balanced liquid fertilizer diluted to half strength is ideal for begonias. Fertilize every 2-3 weeks during the growing season. You can also use a slow-release fertilizer at the beginning of the growing season.
