Discover the Secret to Winter Calla Lily Bulb Storage: How Do I Store Calla Lily Bulbs for the Winter?

Calla lilies, with their elegant trumpet-shaped blooms and vibrant colors, are a beloved addition to any garden. But what happens to these beauties when the cold weather arrives? Knowing how to store calla lily bulbs for the winter is crucial to ensuring they thrive and bloom again in the spring. This guide will walk you through the process of storing your calla lily bulbs, ensuring their safe hibernation and a spectacular return next season.

Why Store Calla Lily Bulbs?

Calla lilies are generally considered hardy plants, but they are not cold-hardy. This means they can tolerate some chill, but prolonged exposure to freezing temperatures can damage or even kill the bulbs. Storing them indoors for the winter allows them to rest and conserve energy, ensuring they have the strength to produce beautiful blooms the following year.

When to Dig Up Calla Lily Bulbs

The best time to dig up your calla lily bulbs is after the first frost, when the leaves have started to die back. This usually occurs in late autumn, around October or November, depending on your region’s climate.

Preparing Calla Lily Bulbs for Storage

Once you’ve dug up your bulbs, it’s important to prepare them for storage:

1. Clean and Dry: Gently brush off any excess soil from the bulbs. Rinse them lightly with water if necessary, but avoid soaking them. Allow the bulbs to dry completely in a warm, well-ventilated area for a few days.

2. Inspect for Damage: Examine the bulbs for any signs of rot, disease, or pests. Discard any damaged bulbs.

3. Cut Back Foliage: Trim any remaining foliage back to about an inch above the bulb.

Choosing the Right Storage Method

There are two primary methods for storing calla lily bulbs:

1. Dry Storage:

• Materials: Paper bags, cardboard boxes, or mesh bags.
• Process: Place the dried bulbs in a single layer in your chosen container. Ensure good airflow by not packing them too tightly.
• Location: Store in a cool, dark, and dry place with temperatures between 40°F and 50°F. A basement, garage, or attic are good options.

2. Refrigerated Storage:

• Materials: Plastic bags or containers.
• Process: Place the dried bulbs in a plastic bag or container, leaving some air space.
• Location: Store in the crisper drawer of your refrigerator.

Maintaining Ideal Storage Conditions

Both dry and refrigerated storage methods require consistent monitoring.

• Temperature: Regularly check the temperature of your storage area. If the temperature fluctuates, adjust the location or use a thermostat to maintain the ideal range.
• Moisture: Avoid over-watering the bulbs. Dry storage should be kept dry, and refrigerated storage should be checked for moisture buildup.
• Ventilation: Ensure good airflow in the storage area to prevent mold and mildew.

Bringing Calla Lily Bulbs Back to Life

When spring arrives, it’s time to wake up your calla lily bulbs!

• Planting Time: Wait until the threat of frost has passed and the soil has warmed up, typically around April or May.
• Planting Depth: Plant your bulbs 2-3 inches deep, with the pointed end facing upwards.
• Watering: Water the bulbs thoroughly after planting, and continue to water regularly as they grow.

The End of the Journey: A New Beginning

By following these steps, you can successfully store your calla lily bulbs for the winter and enjoy their stunning beauty season after season. Remember, proper storage is key to ensuring their health and vitality, allowing them to flourish and grace your garden with their elegance.

Frequently Discussed Topics
