Gladiolus corms are a popular choice for gardeners due to their vibrant flowers and relatively easy care. However, before storing them for the off-season, it is essential to inspect for any signs of disease that could affect future growth. Properly checking your gladiolus corms can prevent the spread of infections and ensure healthy blooms next year.
Understanding Common Gladiolus Diseases
Several diseases can affect gladiolus corms, including:
- Fusarium Wilt: Causes corm rot and wilting of the plant.
- Botrytis Blight: Leads to gray mold on corms and leaves.
- Viral Diseases: Result in streaks or discoloration on corms and leaves.
- Corm Rot: Usually caused by fungal infections, leading to soft, decayed corms.
Steps to Check Gladiolus Corms for Diseases
Follow these steps to thoroughly inspect your gladiolus corms before storage:
1. Remove Soil and Debris
Carefully brush off any soil, dirt, or plant debris from the corms. Use a soft brush or cloth to avoid damaging the surface.
2. Examine the Exterior
Inspect the surface for any signs of damage, discoloration, or mold. Look for soft, shriveled, or discolored areas which may indicate disease.
3. Check for Softness and Texture
Gently squeeze the corms. Healthy corms should be firm. Soft or mushy spots are signs of rot or infection.
4. Look for Fungal Growth or Mold
Any fuzzy, gray, or white mold indicates fungal infection. Such corms should be discarded or treated carefully.
Disinfect and Treat Suspect Corms
If you find minor issues, some corms can be treated to prevent disease spread. Dip them in a fungicide solution or a mixture of one part bleach to nine parts water for about 10 minutes. Rinse thoroughly and dry in a well-ventilated space.
Proper Storage Tips
Once inspected and treated, store your gladiolus corms in a cool, dry, and well-ventilated area. Use paper bags or mesh containers to allow airflow. Avoid storing in plastic bags, which can trap moisture and promote rot.
Conclusion
Regular inspection of gladiolus corms before storage is vital for maintaining healthy plants and vibrant flowers. By following these steps, you can reduce the risk of disease and enjoy beautiful blooms year after year.
