How to plant begonia corms
Are you ready to add some vibrant color and beauty to your garden or indoor space?
Look no further than begonias! These stunning flowering plants are known for their bright blooms and lush foliage, making them a popular choice for gardeners of all skill levels.
One of the easiest ways to grow begonias is from corms, which are the underground storage organs of the plant. Planting begonia corms is a simple and rewarding process that can yield beautiful results. In this article, we will guide you through the steps of planting begonia corms and provide you with helpful tips for ensuring their successful growth.
What are begonia corms?
Begonia corms are a type of underground stem that is used by the begonia plant to store nutrients and energy during its dormant period. These corms are swollen, bulb-like structures that can vary in size depending on the species of begonia. They are typically round or oblong in shape and have a brown outer skin.
When the growing season begins, the begonia corms send out shoots from their tops, which eventually develop into the plant’s leaves and flowers. As the plant grows, it relies on the stored nutrients in the corms to fuel its growth and development.
Begonia corms are commonly used in gardening as they are easy to plant, grow, and propagate. They are especially popular for their stunning flowers, which come in a wide range of colours and forms. The corms can be planted directly into the soil or started indoors for earlier blooms, and they are typically planted with the top of the corm facing upwards.
Overall, begonia corms play a crucial role in the lifecycle of the begonia plant, providing it with the necessary resources to thrive and produce beautiful flowers. By understanding and properly caring for these corms, gardeners can enjoy the vibrant beauty of begonias in their own gardens.
Choosing the Right Begonia Corms
When it comes to planting begonias, choosing the right corms is essential for ensuring strong and healthy plants. Here are a few factors to consider when selecting begonia corms:
1. Variety
Begonias come in various varieties, each with its own unique characteristics and growth requirements. Choose a variety that suits your preferences and the conditions in your garden. Common begonia varieties include tuberous begonias, fibrous begonias, and rex begonias.
2. Size and Shape
The size and shape of begonia corms can vary significantly. Larger corms tend to produce larger plants with more flowers, while smaller corms may take longer to establish and result in smaller plants. Consider the size restrictions of your garden and choose corms that will fit well.
3. Quality
Inspect the corms thoroughly before purchasing to ensure they are healthy and free from any signs of disease or damage. Look for corms that are firm, plump, and free from soft spots or mold. High-quality corms will give you the best chance of success in growing healthy begonias.
4. Supplier
Choose a reputable supplier that specializes in begonia corms. Look for suppliers with positive reviews and feedback from other gardeners. They will be more likely to provide you with high-quality corms that are true to their variety.
By taking the time to choose the right begonia corms, you can ensure that your plants have the best chance of thriving in your garden. Plan ahead and select corms that match the conditions in your garden and your personal preferences. With the right corms, you’ll soon be rewarded with beautiful begonias in full bloom.
Preparing the soil for planting
Before planting begonia corms, it is important to prepare the soil to ensure optimal growing conditions for your plants. Follow these steps to create the ideal planting environment:
|
1. Choose a well-draining location: Find a spot in your garden that receives partial shade or filtered sunlight for at least a few hours each day. Begonias prefer well-drained soil, so avoid areas that tend to get waterlogged. |
2. Clear the area: Remove any weeds, grass, or debris from the planting area. This will help prevent competition for nutrients and create a clean space for your begonias to grow. |
|
3. Loosen the soil: Using a garden fork or a tiller, loosen the soil in the planting area to a depth of at least 6-8 inches. This will help improve drainage and allow the roots of the begonias to spread more easily.  10 Mixed Double Begonias Tuberous Bulbs/Corms for Garden & Tubs Stunning Summer Plant : - by GARTHWAITE NURSERIES®: - UK Stockist

4. Add organic matter: Mix in a generous amount of organic matter such as compost or well-rotted manure into the loosened soil. This will provide essential nutrients and improve the soil structure, creating a fertile and friable planting medium for the begonias. |
|
5. Test the soil pH: Check the soil pH using a soil testing kit. Begonias prefer a slightly acidic to neutral pH range of 6.0 to 7.0. If the soil is too acidic or alkaline, you may need to amend it with lime or sulfur to adjust the pH accordingly. |

Planting begonia corms
Planting begonia corms is a straightforward process that can be done in a few easy steps. Here is a step-by-step guide to help you successfully plant your begonia bulbs:
- Choose a suitable planting location. Begonias prefer well-draining soil and partial shade, so find an area in your garden or use containers that meet these requirements.
- Prepare the soil or container. If planting in the ground, loosen the soil and remove any weeds or debris. If using containers, ensure they have drainage holes and fill with a well-draining potting mix.
- Soak the begonia corms. Before planting, soak the corms in water for a few hours or overnight. This helps them absorb moisture and kickstart the growing process.
- Dig holes or create planting furrows. For each corm, dig a small hole or create a furrow that is about 1-2 inches deep. Space the holes or furrows 6-12 inches apart, depending on the size of your begonia variety.
- Plant the corms. Place each soaked corm in a hole or furrow with the concave side facing up. Cover the corms with soil, gently firming it around them.
- Water thoroughly. After planting, water the corms thoroughly to settle the soil and provide much-needed moisture. Avoid overwatering, as this can lead to rotting.
- Maintain the right environment. Throughout the growing season, provide consistent moisture and partial shade for your begonias. Regularly monitor soil moisture levels and adjust watering as necessary.
- Monitor growth and provide care. As your begonias grow, check for any signs of pests or diseases. Remove any faded flowers or yellowing leaves to maintain plant health.
By following these steps, you can ensure successful planting of your begonia corms and enjoy beautiful blooms in your garden or containers.
Caring for Begonia Corms
After planting begonia corms, it’s important to provide the proper care to ensure their healthy growth and vibrant blooms. Here are some essential tips for caring for begonia corms:
1. Watering:
Begonia plants prefer moist soil, so make sure to water them regularly. However, be careful not to overwater, as excessive moisture can cause the corms to rot. It’s best to water when the top inch of soil feels dry. Water at the base of the plant to avoid wetting the leaves, as this can lead to fungal diseases.
2. Fertilization:
To promote healthy growth and blooming, feed your begonia corms with a balanced, water-soluble fertilizer every two weeks during the growing season. A fertilizer with equal amounts of nitrogen, phosphorus, and potassium is ideal for begonias.
3. Light Requirements:
Begonias thrive in bright, indirect light. They prefer dappled shade or morning sun, but direct afternoon sun can be too intense and scorch their delicate foliage. Choose a location with filtered light or provide shade during the hottest part of the day.
4. Temperature:
Begonias are tropical plants that thrive in temperatures between 60°F and 75°F (15°C and 24°C). Protect begonia corms from frost and freezing temperatures, as they are sensitive to cold. If you live in a colder climate, it’s best to grow begonias as annuals or bring them indoors during winter.
5. Pruning:
To maintain a compact and bushy begonia plant, pinch back the tips of the stems periodically. This will encourage branching and more flower production. Remove any dead or yellowing leaves to prevent disease spread and improve the overall appearance of the plant.
6. Pests and Diseases:
Watch out for common begonia pests like aphids, spider mites, and mealybugs. Treat infestations promptly with insecticidal soap or neem oil to prevent further damage. Avoid overhead watering and provide good air circulation to minimize the risk of fungal diseases like powdery mildew.
By following these care tips, you can ensure the health and beauty of your begonia corms, enjoying their stunning flowers throughout the growing season.
