Discover the Secret to Growing Gorgeous Begonias: How to Plant Begonia Corms

Begonia corms are a gardener’s delight, offering vibrant blooms and lush foliage that can brighten up any space. These fascinating underground storage organs hold the key to a successful begonia planting journey. This comprehensive guide will walk you through the process of how to plant begonia corms, from selecting the right corms to nurturing them into thriving plants.

Understanding Begonia Corms

Begonia corms are essentially thickened stems that store nutrients and energy for the plant. They are typically round or oval-shaped and have a rough, brown outer layer. Unlike bulbs, which have layers, corms are solid structures. These corms are dormant during the winter months and come to life when planted in the spring.

Choosing the Right Begonia Corms

Selecting healthy begonia corms is crucial for successful planting. Look for corms that are firm, plump, and free from any signs of damage, rot, or mold. Avoid corms that are shriveled or have soft spots.

Preparing for Planting

Before planting your begonia corms, you need to prepare the soil and containers. Here’s how:

• Soil Selection: Begonia corms thrive in well-draining, slightly acidic soil. A good potting mix that contains peat moss, vermiculite, and perlite is ideal.
• Container Choice: Choose pots that are slightly larger than the corm’s diameter. Ensure that the pots have drainage holes to prevent soggy soil.
• Watering: Water the soil thoroughly before planting to ensure it’s moist but not waterlogged.

Planting Begonia Corms

Now, it’s time to plant your begonia corms:

1. Planting Depth: Bury the corm about 1-2 inches deep in the soil, with the pointed end facing upwards.
2. Spacing: Allow adequate space between corms, depending on the variety. Refer to the specific instructions for your begonia type.
3. Watering: After planting, gently water the soil to settle the corms.

Providing Optimal Growing Conditions

Once planted, your begonia corms need the right conditions to thrive. Here are some essential tips:

• Sunlight: Begonia corms prefer bright, indirect light. Avoid direct sunlight, as it can scorch the leaves.
• Temperature: Maintain a warm temperature between 65-75°F (18-24°C) for optimal growth. Begonia corms are sensitive to frost and cold temperatures.
• Humidity: Begonia corms appreciate high humidity. You can increase humidity by placing the pots on a tray filled with pebbles and water.
• Fertilization: Feed your begonia corms with a balanced liquid fertilizer every two weeks during the growing season.

Caring for Your Begonia Corms

Regular care is essential for healthy begonia growth:

• Watering: Water the soil consistently, allowing it to dry slightly between waterings. Avoid overwatering, which can lead to root rot.
• Deadheading: Regularly remove spent flowers to encourage new blooms.
• Pruning: Pinch back the tips of the stems to promote bushier growth.
• Pest and Disease Control: Monitor your plants for pests like aphids and mealybugs. Use appropriate pest control methods if necessary.

Overwintering Begonia Corms

Begonia corms are not fully hardy in colder climates. To ensure their survival during winter, you need to overwinter them:

1. Cut Back: Once the first frost arrives, cut back the foliage to about 2 inches above the soil.
2. Dig Up: Carefully dig up the corms and gently remove any excess soil.
3. Drying: Allow the corms to dry completely in a cool, dry place.
4. Storing: Store the dried corms in a paper bag or cardboard box in a cool, dark, and dry location until spring.

A New Beginning: Planting Begonia Corms in Spring

Once the threat of frost has passed, you can replant your begonia corms. Follow the same planting instructions as mentioned earlier, and enjoy the vibrant blooms that await.

Beyond Blooms: The Beauty of Begonia Corms

Begonia corms offer more than just stunning blooms. Their foliage comes in a range of colors, textures, and patterns, adding visual interest to any garden or indoor space.

Final Thoughts: A Journey of Growth and Renewal

Planting begonia corms is a rewarding experience. By understanding their needs and providing the right care, you can witness the remarkable transformation from dormant corms to vibrant, flowering plants. Each spring, you can enjoy the beauty of these remarkable flowers, a testament to the resilience of nature and the joy of gardening.

Answers to Your Questions

1. How long does it take for begonia corms to bloom?

Begonia corms typically start blooming 6-8 weeks after planting, but the exact time may vary depending on the variety and growing conditions.

2. Can I plant begonia corms directly in the ground?

Yes, you can plant begonia corms directly in the ground, but only if your climate is warm enough for them to thrive. In colder climates, it’s best to plant them in containers that can be brought indoors during the winter.

3. What are the signs of a diseased begonia corm?

Signs of a diseased corm include soft spots, discoloration, mold growth, and a foul odor. Discard any diseased corms to prevent the spread of disease to other plants.

4. Can I divide begonia corms?

Yes, you can divide begonia corms to create new plants. However, it’s best to divide them only when the corms are dormant.

5. Can I start begonia corms from seed?

Yes, you can start begonia corms from seed, but it’s a more time-consuming process than planting corms. Seed-grown begonias may take longer to bloom, and they might not be as vigorous as those grown from corms.
