Calla lilies, with their elegant trumpet-shaped blooms, add a touch of sophistication to any garden. But what happens to these beauties when the weather turns frosty? How do you winterize calla lily bulbs to ensure they return with vibrant blooms the following spring? This guide will walk you through the process, ensuring your calla lilies thrive through the winter months.
Understanding Calla Lily Bulbs
Calla lilies are not true lilies, but rather members of the arum family. They are perennial plants, meaning they live for more than two years, and their beauty lies in their striking, showy flowers that emerge from a single, elegant spadix. Calla lilies are also popular houseplants, but their bulb-like rhizomes need special care during the winter months.
When to Winterize Calla Lily Bulbs
The timing of winterizing your calla lily bulbs depends on your climate. If you live in a region with mild winters, you may not need to winterize them at all. However, if you experience frost or freezing temperatures, you’ll need to bring your bulbs indoors.
Here’s a general guideline:
- Cold climates: Start winterizing your calla lily bulbs in late fall, before the first frost.
- Warm climates: You can leave your calla lilies in the ground during the winter, but it’s a good idea to mulch them to protect them from extreme temperatures.
Preparing Calla Lily Bulbs for Winterization
Before you begin winterizing, ensure your calla lily bulbs are healthy and free of diseases. Here’s how to prepare them:
1. Cut Back the Foliage: Once the foliage starts to turn yellow or brown, cut it back to about 2 inches above the soil. This will help prevent disease and pests.
2. Dig Up the Bulbs: Carefully dig up the calla lily bulbs, being sure to get the entire rhizome. Use a garden fork or spade to gently loosen the soil around the bulbs before lifting them.
3. Clean the Bulbs: Brush off any excess soil from the bulbs. Inspect them for any signs of disease or pests. If you find any, discard the affected bulbs.
Storing Calla Lily Bulbs for Winter
Once you’ve prepared your calla lily bulbs, you need to store them properly for the winter. Here’s how:
1. Drying the Bulbs: Allow the bulbs to air dry in a cool, dry place for a few days. This will help prevent rot.
2. Choosing the Right Storage Container: Select a breathable container, such as a mesh bag or a cardboard box with holes punched in it. Avoid plastic bags or airtight containers, as they can trap moisture and cause the bulbs to rot.
3. Storing the Bulbs: Place the dried bulbs in the container, ensuring they are not touching each other. Store the container in a cool, dark, and dry place, such as a basement, garage, or attic. The ideal temperature for storage is between 40°F and 50°F (4°C and 10°C).
Tips for Successful Winterization
- Avoid storing bulbs in areas with fluctuating temperatures. This can cause them to rot.
- Check the bulbs periodically for any signs of rot or mold. If you find any, remove the affected bulbs immediately.
- Do not fertilize your calla lilies during the winter months. They are dormant and do not need nutrients.
Bringing Your Calla Lily Bulbs Back to Life
When spring arrives, it’s time to wake up your dormant calla lily bulbs. Here’s how to do it:
1. Planting: Plant the bulbs in well-draining soil in a sunny location. The depth of planting should be twice the height of the bulb.
2. Watering: Water the bulbs thoroughly after planting. Keep the soil moist, but not soggy.
3. Fertilizing: Once the foliage emerges, you can start fertilizing your calla lilies with a balanced fertilizer.
4. Enjoy the Blooms: With proper care, your calla lilies should start blooming in late spring or early summer.
Beyond Winterization: Ensuring Continued Calla Lily Health
Winterization is a crucial step, but it’s just one part of ensuring your calla lilies thrive. Here are some additional tips:
- Choose the Right Location: Calla lilies prefer sunny locations with well-draining soil.
- Water Consistently: Keep the soil moist, but avoid overwatering.
- Provide Adequate Fertilizer: Fertilize your calla lilies regularly during the growing season.
- Protect from Pests and Diseases: Monitor your plants for any signs of pests or diseases.

Winterizing your calla lily bulbs is a simple yet essential step to ensure a vibrant display of blooms the following spring. By following these steps, you can ensure your calla lilies remain healthy and beautiful throughout the winter months and bring a touch of elegance to your garden come spring.
