Effective Ways to Store Iris Rhizomes for Longevity

Iris plants are beautiful flowers that come in many colors and varieties, adding a touch of elegance to any garden. However, they require specific care and attention, especially when it comes to storing their rhizomes during the off-season. In this blog post, we will explore everything you need to know about how to store iris rhizomes properly.

What Are Iris Rhizomes?

Before we dive into storage techniques, let’s first define what iris rhizomes are. Rhizomes are modified stems that grow horizontally underground and produce roots from their nodes. For irises, these structures serve as both food storage organs and propagation methods.

The Importance of Storing Iris Rhizomes

Storing iris rhizomes correctly is crucial for ensuring the health and longevity of your plants. Improper storage can lead to diseases such as bacterial soft rot or fungal infections that damage or even kill your plants.

When Should You Store Iris Rhizomes?

Typically you should store iris rhizomes in late summer or early fall after they have finished blooming for the season.

Your Storage Space Matters!

Choose a dry area with good ventilation where temperatures remain between 40-50°F (4-10°C). A garage or basement works well if it meets these conditions.

Preparing Your Iris Rhizome

Before storing them away for winter make sure the foliage on each plant has died down completely before digging up its root system. This signals that energy transfer from foliage growth has completed its cycle leaving food reserves stored inside the bulb-like structure at its base called a “rhizome.” Cut off any remaining leaves with sharp scissors then gently lift each clump out of soil using a pitchfork taking care not to damage tender sprouts starting anew from attached roots. Rinse under running water to remove soil and debris.

How To Store Iris Rhizomes

Now that you’ve harvested your iris rhizomes let’s dive into how to store them properly.

Clean Your Rhizomes

Wipe each one dry with a clean cloth or towel then inspect closely for signs of damage, disease or insect infestation. Discard any damaged bulbs as they will not survive the winter storage process. Sprinkle powdered sulfur over the entire surface of each rhizome until covered before placing in mesh bags specifically designed for bulb storage.

Avoid Overcrowding

Avoid overcrowding container space when storing iris rhizomes by using individual mesh bags. This ensures sufficient air circulation around them, reducing risk of fungal spores developing while keeping pests at bay.

Store Them In A Cool And Dry Location

Find a cool and dry location away from direct sunlight like an unheated garage or basement where temperatures remain between 40-50°F (4-10°C). Avoid damp areas which can promote mold growth especially if you live in humid climates where moisture is abundant year-round.

In Conclusion

Knowing how to store iris rhizomes correctly is essential for ensuring their health and longevity. Following these simple steps will give you the best chance of enjoying your beautiful irises year after year without any issues!
