Step-by-Step Guide to Collecting Gladiolus Bulbs
1. Dig Around the Base: Using a garden trowel or spade, carefully dig around the base of the plant, about 6-8 inches deep. Avoid damaging the bulbs.
2. Lift and Brush Off Soil: Gently lift the plant out of the ground and brush off any excess soil from the bulbs.
3. Remove Stems: Cut off the stems, leaving about 1 inch above the bulb.
4. Separate Corms: The main bulb is surrounded by smaller corms. Carefully separate these corms by gently pulling them apart.
5. Inspect for Damage: Examine the bulbs for any signs of damage, disease, or rot. Discard any damaged bulbs.
6. Clean and Disinfect: Use a sharp knife to remove any remaining roots or debris from the bulbs. Disinfect the bulbs by soaking them in a fungicide solution for 10-15 minutes.
7. Dry and Store: Spread the bulbs out on newspaper or paper towels in a warm, dry place with good ventilation. Allow them to dry for several weeks until they feel firm and papery to the touch.
Preparing Bulbs for Storage
- Remove Outer Husks: Once the bulbs are dry, remove any loose outer husks.
- Label: Label each variety of bulb with its name and the year it was harvested.
- Store: Store the bulbs in a cool, dry, and well-ventilated place. The ideal temperature range is between 40-50°F (4-10°C).
Tips for Success
- Dig the bulbs when the soil is dry to prevent disease.
- Handle the bulbs gently to avoid bruising.
- Disinfecting the bulbs helps prevent fungal infections.
- Allow the bulbs to dry thoroughly before storing to prevent rot.
- Avoid storing bulbs in plastic bags, as they trap moisture.
Troubleshooting
- Bulbs are soft or mushy: Discard any soft or mushy bulbs as they are likely infected with a disease.
- Bulbs have brown spots: Cut out any brown spots with a sharp knife and treat the bulbs with a fungicide.
- Bulbs are not sprouting: Check if the bulbs are viable by placing them in warm water for a few hours. If they float, discard them.
