Preparing Gladiolus Bulbs for Storage
To keep your gladiolus bulbs healthy and ready to bloom again next year, you’ll need to properly clean and dry them before storing. This ensures they don’t rot over winter.
Cleaning and Drying
Before storing your gladiolus bulbs for winter, it’s essential to clean and dry them thoroughly. This process helps prevent rot and mildew from developing during the storage period.
Begin by gently removing excess soil from the bulbs using a soft-bristled brush or a gentle scrubber. Rinse the bulbs with lukewarm water to remove any remaining dirt. Make sure to pat them dry with a clean towel, paying extra attention to the crown (where the stem meets the bulb).
Allow the bulbs to air-dry for 2-3 days in a warm, well-ventilated area, away from direct sunlight. This helps prevent moisture from accumulating on the bulbs’ surface. You can also speed up the drying process by placing the bulbs on a wire rack or paper towels.
Once dry, inspect each bulb for any signs of damage or rot. Discard any bulbs that are severely affected to prevent the spread of disease to healthy bulbs. Properly cleaned and dried gladiolus bulbs will be ready for storage in their winter home, free from excess moisture and debris.
Allowing Proper Curing Time
Allowing proper curing time is a crucial step in preparing gladiolus bulbs for storage. This process allows the bulbs to dry out slightly, which helps prevent rot and decay during storage. When you harvest gladiolus flowers in the fall, the stalks are still attached to the bulb. To cure the bulb properly, leave it with these dried stalks intact for 1-2 weeks after cutting.
During this time, keep the bulbs in a warm, dry location with temperatures between 60°F (15°C) and 70°F (21°C). Avoid direct sunlight, as it can cause the bulb to over-dry. After 7-10 days, you’ll notice the dried stalks turning brown and becoming brittle. This indicates that the curing process is complete.
It’s essential not to cut off the dried stalks too early, as this can damage the bulb and lead to rot. Also, don’t leave them on for too long, as this can cause the bulb to become too dry and potentially crack when stored.
Storing Gladiolous Bulbs in a Cool Place
When storing gladiolus bulbs, it’s essential to provide them with a cool, dry place where they can hibernate over winter, without risk of rot or moisture damage. This section explains how to keep your bulbs safe and healthy until spring.
