Digging Up Gladiolus Corms
1. Check for Ripeness: Before digging, check if the gladiolus corms are ripe. The leaves should turn yellow and start to die back, and the corm should feel firm to the touch.
2. Dig Carefully: Using a garden fork, carefully dig around the base of the gladiolus plant, avoiding damage to the corms. Lift the corms gently out of the soil.
Cleaning and Drying Gladiolus Corms
3. Remove Soil and Debris: Brush off any excess soil and debris from the corms. Do not wash them with water, as this can promote disease.
4. Dry in a Warm, Ventilated Area: Spread the corms out on a tray or newspaper in a warm, well-ventilated area. Allow them to dry for several days or until they are completely dry.
Inspecting and Treating Corms
5. Inspect for Damage: Carefully examine the corms for any signs of damage, disease, or pests. Remove any damaged or diseased corms.
6. Treat for Pests and Diseases: If necessary, treat the corms with a fungicide or insecticide to prevent pests and diseases from overwintering.
Curing and Storing Gladiolus Corms
7. Cure the Corms: Place the corms in a cardboard box or paper bag and store them in a warm, dark place for about four weeks. This curing process helps the corms develop a protective layer.
8. Store in a Cool, Dry Place: After curing, store the gladiolus corms in a cool, dry place with good ventilation. The ideal temperature range is between 45-55°F (7-13°C).
Additional Tips
- Avoid Freezing: Gladiolus corms are not frost-hardy. Protect them from freezing temperatures by storing them indoors or in a heated garage.
- Check Corms Regularly: Inspect the corms periodically during storage to ensure they remain dry and free from pests or diseases.
- Discard Diseased Corms: If you notice any signs of disease or rot, discard the affected corms immediately.
