Step-by-Step Guide

After harvesting, it is important to clean the gladiolus bulbs thoroughly to remove any soil and debris.

1. Wash the bulbs gently with water to remove soil.
2. Let the bulbs dry in a warm, sunny location for a few days.

Curing is necessary to help the bulbs heal and prepare for storage.

1. Place the bulbs in a warm, dry area with good airflow for at least one week.
2. During this time, check for any old corms and remove them carefully to prevent disease.

It’s important to check the bulbs for any signs of disease before storage.

1. Look for dark spots or mushy areas on the bulbs; these may indicate disease.
2. Discard any bulbs that show signs of rot or disease to protect the healthy ones.

Proper storage conditions are crucial for the survival of your gladiolus bulbs through the winter.

1. Use mesh bags or screen-bottom flats to allow for airflow around the bulbs.
2. Store the bulbs in a cool, dry place, ideally in a heated garage set to around 45 degrees Fahrenheit.

Regular checks on the stored bulbs can help ensure they remain healthy.

1. Inspect the bulbs every few weeks for signs of moisture or decay.
2. Adjust storage conditions as necessary to maintain optimal humidity and temperature.
