Gladiolus corms are a popular choice for gardeners looking to add vibrant color to their gardens. Properly identifying healthy corms is essential for successful division and future growth. This guide provides key tips to help you select the best corms for propagation.
Understanding Gladiolus Corms
Gladiolus plants grow from corms, which are underground storage organs. These corms produce new growth each season and can be divided to propagate new plants. Healthy corms are crucial for vigorous growth and abundant flowers.
Signs of Healthy Gladiolus Corms
- Firmness: The corm should feel firm and solid when gently squeezed. Soft or mushy corms are signs of decay or disease.
- Size: Look for large, plump corms relative to their variety. Larger corms generally produce stronger plants.
- Color: Healthy corms are usually a healthy, consistent color, such as tan or light brown. Avoid corms with dark spots or discoloration.
- Surface: The surface should be smooth and free of mold, moldy patches, or fungal growth.
- Eyes: Check for multiple healthy “eyes” or growth points on the corm. These indicate good potential for sprouting.
How to Inspect Corms Before Division
When dividing gladiolus corms, carefully examine each one for the signs listed above. Remove any damaged or diseased parts with a sterile knife. Discard soft, shriveled, or moldy corms to prevent disease spread.
Preparing Corms for Division
After selecting healthy corms, gently loosen the soil around them and lift them carefully. Use a clean, sharp knife to divide large corms into smaller sections, ensuring each division has at least one healthy eye or growth point.
Steps for Dividing Corms
- Wash the corms to remove soil and debris.
- Use a sterile knife to cut into the corm, separating healthy sections.
- Allow the divisions to dry in a cool, well-ventilated area for a day or two.
- Store the divided corms in a dry, dark place until planting.
Conclusion
Choosing healthy gladiolus corms is key to successful propagation and vibrant blooms. By inspecting for firmness, size, color, and healthy eyes, gardeners can ensure their divisions will thrive in the upcoming growing season. Proper handling and storage further enhance the chances of a beautiful garden display.
