How To Store Iris Bulbs

1. Select the Right Location for Storing Iris Bulbs 

When storing iris bulbs, selecting the right location is crucial to ensuring their longevity. Remember that iris bulbs require a cool, dry environment with good air circulation. 

The ideal temperature range for storing iris bulbs is between 35°F and 45°F, while humidity levels should be below 60%. 

1. Select the Right Location for Storing Iris Bulbs 

We recommend storing iris bulbs away from direct sunlight, as exposure to light and heat can cause premature drying and damage. Consider storing your iris bulbs in a cool, dry basement, garage, or refrigerator. 

Choosing the proper location can help ensure your iris bulbs remain healthy and viable for years.

2. Prepare the Storage Area to Store Iris Bulbs

Prepare the storage area for storing iris bulbs; it is necessary to free up a designated space that is well-ventilated, cool, dry, and away from direct sunlight. The storage area should be clean and free of any dampness or moisture, which can lead to rot or fungus growth. 

Good options for storage containers include cardboard boxes, mesh baskets, or paper or mesh bags. These containers should be labeled accordingly, indicating the type of iris bulbs and the date they were stored. 

2. Prepare the Storage Area to Store Iris Bulbs

It is important to inspect the bulbs for any signs of disease or damage before storage and discard any bulbs showing such symptoms. 

Creating a proper storage area can ensure the longevity and health of their iris bulbs for their next blooming season.

3. Select the Right Containers for Storing Iris Bulbs 

When storing iris bulbs, choosing the right containers ensures longevity and viability. 

One of the most important factors in selecting containers is ensuring they are clean and dry to prevent mold or bacterial growth. 

3. Select the Right Containers for Storing Iris Bulbs 

The containers must have good ventilation to prevent any moisture buildup. Plastic, mesh, or paper bags are all great container options. 

When choosing plastic, opt for a breathable type, and when using paper or mesh, ensure they are in a cool and dry location. 

Sealable, airtight containers or bags should be avoided, as they can trap moisture and cause the bulbs to rot. 

It is also important to label the containers correctly to keep a record of the species, date of storage, and any other relevant information that will help retrieve them in the future. 

By following these guidelines, you can help ensure the successful storage of your iris bulbs for months to come.

4. Clean the Iris Bulbs Before Storage

If you are looking to store iris bulbs for a long time, it is important to ensure they are clean and dry before storage. This step will help to prevent rot and disease and make it easier for bulbs to survive winter storage. 

Remove any remaining foliage or dirt from the roots to clean the iris bulbs. Then, gently rinse the bulbs in a solution of one part bleach to nine parts waters. It will help to sanitize the bulbs and prevent the growth of fungus and bacteria. 

After cleaning, ensure the bulbs are dry by leaving them to air dry for at least 24 hours. Once completely dry, store the bulbs in a cool, dry place until it is time for planting or propagation. 

By following these simple steps, you can ensure that your iris bulbs survive storage and provide a beautiful addition to your garden in the coming year.

5. Package the Iris Bulbs for Storage

Proper packaging is essential to preserve its quality when storing iris bulbs. Here are the steps to follow when packaging iris bulbs for storage:

5. Package the Iris Bulbs for Storage
  • Start by cleaning the bulbs. Remove any dirt or debris and let them dry completely before packaging.
  • Place the bulbs in a paper bag or a cardboard box. Avoid using plastic, as it can cause the bulbs to sweat and rot.
  • Add peat moss or vermiculite to the bag or box to help absorb any moisture.
  • Label the package with the variety and date of harvest to keep track of the bulbs.
  • Store the package in a cool, dry, dark location like a basement or a garage where the temperature remains between 35-45°F (2-7°C).

These steps will help ensure your iris bulbs remain healthy and viable for the next planting season. 

6. Place the Iris Bulbs in the Storage Container 

Following a few key steps to store iris bulbs properly is important. One of the final steps of the process involves placing the iris bulbs in the storage container. Select a thoroughly cleaned container and completely dry it before adding your bulbs. 

6. Place the Iris Bulbs in the Storage Container 

When placing the bulbs in the container, it is best to avoid overcrowding and leave space between each bulb. 

Using a layer of vermiculite or peat moss between the bulbs can help to protect them from moisture and ensure adequate air circulation. 

Once the bulbs are securely in the container, seal them tightly and store them in a cool, dry location. 

By following these steps, you can help to ensure that your iris bulbs remain healthy and viable for the next growing season.

7. Add a Protective Layer to the Storage Container 

Protecting iris bulbs from various external factors that may cause damage when storing them is important. 

One effective way to preserve the quality of your iris bulbs is to add a protective layer to the storage container. It can do by lining the container with peat moss or sawdust. 

7. Add a Protective Layer to the Storage Container 

The protective layer will help to prevent moisture from accumulating in the container, which can lead to mold and rotting of the bulbs. 

Additionally, the layer can help to insulate the bulbs from extreme temperature fluctuations and protect them from potential damage caused by rodents or insects. Taking these precautions ensures that your iris bulbs will remain healthy and viable for planting.

8. Store the Iris Bulbs in a Cool Location

Storing iris bulbs is essential for ensuring their growth and blooming next season. As fall approaches, it’s important to know the right techniques for storing iris bulbs to ensure healthy growth and a beautiful display of springtime blooms. One of the most important factors in storing iris bulbs is to store them in a cool location. 

8. Store the Iris Bulbs in a Cool Location

The bulbs need a dormant period to rest, rejuvenate, and prepare for their next blooming season. A cool location ensures that the temperature remains consistently between 35°F and 45°F. 

This range simulates the cool, damp soil in which the bulbs are used to growing and helps to prevent them from drying out. It’s important to avoid storing the bulbs in locations that get too warm or humid, which can cause them to rot or sprout too soon. 

Properly storing iris bulbs in a cool location is crucial to their health and the success of your springtime display.

9. Ensure Proper Air Circulation in the Storage Area

Proper air circulation is crucial to store iris bulbs. If the storage area lacks airflow, moisture can accumulate and cause the bulbs to rot. Therefore, it is essential to ensure proper ventilation in the storage area. 

9. Ensure Proper Air Circulation in the Storage Area

You can achieve this by opening windows, using fans, or installing ventilation systems. Moreover, storing the bulbs in an area with a consistent temperature and humidity level is better. If the storage area is too humid, use a dehumidifier to reduce moisture. 

Too dry conditions can cause the bulbs to dry out and lose their viability, so monitoring and maintaining the humidity levels in the storage area is crucial. 

Proper airflow and humidity levels in the storage area can help prevent mold growth and other pests, ensuring the bulbs remain healthy and viable for replanting.

10. Check the Iris Bulbs Regularly During Storage

If you’re interested in storing iris bulbs long-term, taking key steps is important to ensure their survival. One of these steps is to check the bulbs regularly during storage. 

Iris bulbs can be susceptible to rot and other damage if not properly stored, so it is important to monitor them for signs of trouble. 

10. Check the Iris Bulbs Regularly During Storage

Generally, you’ll want to inspect your stored bulbs every few weeks, looking for any signs of softness, discoloration, or other issues. 

If you notice any problems, you can remove those bulbs from storage and either try to save them or discard them. 

By staying vigilant and checking your iris bulbs regularly, you can help ensure they remain healthy and viable for many years.

11. Replant the Iris Bulbs After Storage

Replanting iris bulbs after storage is essential to ensure their longevity and growth. Proper storage conditions are crucial to maintaining the quality of the bulbs. Once the bulbs are stored over the summer, they must replant in the fall before the first frost. 

Planting the iris bulbs in well-drained soil in a location that receives at least six hours of direct sunlight is recommended. It is necessary to plant the bulbs about 4 inches deep and 12 inches apart from each other. 

Moreover, watering the bulbs is crucial to promote their growth. By following these simple steps, one can store and replant iris bulbs successfully.

12. Rotate the Iris Bulbs During Storage

When it comes to storing iris bulbs, one important aspect to consider is the rotation of the bulbs during storage. 

This practice involves periodically checking and turning the bulbs to prevent them from developing mold or rot. Properly rotating the iris bulbs ensures they remain healthy and viable for the next growing season. 

We recommend storing the bulbs in a cool, dry place with good air circulation. By rotating the bulbs during storage, gardeners can help ensure a successful and beautiful iris garden in the coming year.

13. Dispose of Iris Bulbs that are Not Viable for Replanting 

When it comes to iris bulbs, it is essential to dispose of any that are not viable for replanting. It is crucial for maintaining the overall health of your iris garden. Store only high-quality, healthy bulbs free from disease or damage. 

13. Dispose of Iris Bulbs that are Not Viable for Replanting 

To determine if an iris bulb is viable for replanting, check for any visible signs of damage or disease, such as rot, mold, or discoloration. 

It is best to dispose of the bulb if any signs are present. Properly disposing of non-viable bulbs can prevent the spread of disease and ensure the success of your iris garden for years to come.

14. Dispose of the Old Containers Properly

Properly disposing of old containers when storing iris bulbs is crucial in maintaining longevity and health. Neglecting to do so can damage the bulbs and ultimately reduce their lifespan. 

It is important to ensure that the containers used for storing the bulbs are clean and free of any prior plant material or soil. 

14. Dispose of the Old Containers Properly

Placing the bulbs in a new container with adequate ventilation and drainage can also help prevent mold and disease. 

Taking the time to dispose of old containers properly can save gardeners time and money in the long run by promoting healthy plant growth and avoiding potential disease issues.
