As autumn’s embrace transforms the garden landscape, it’s time to prepare your beloved calla lilies for the winter slumber. Preserving their bulbs ensures their vibrant blooms will grace your garden again next spring. This comprehensive guide will unveil the secrets of how to save calla lily bulbs for winter, ensuring their vitality and longevity.
Digging Up the Bulbs
When the foliage of your calla lilies turns yellow and begins to die back, it’s a sign that the bulbs are ready to be lifted. Dig carefully around the base of the plant, using a shovel or trowel. Avoid damaging the bulbs, as any nicks or cuts can provide an entry point for disease.
Cleaning and Drying
After digging up the bulbs, gently shake off any excess soil. Rinse them thoroughly under running water to remove any remaining dirt or debris. Allow the bulbs to air-dry in a warm, well-ventilated area for several days.
Curing
The curing process helps to harden the bulbs and prepare them for storage. Place the bulbs in a single layer in a cardboard box or crate lined with newspaper or sawdust. Store them in a cool, dark, and dry location with good air circulation. The ideal curing temperature is between 40-50°F (4-10°C). Allow the bulbs to cure for 4-6 weeks.
Inspecting and Sorting
Once the bulbs have cured, inspect them carefully for any signs of damage, disease, or pests. Discard any bulbs that are soft, mushy, or have visible blemishes. Sort the healthy bulbs by size, separating larger bulbs from smaller ones.
Storage
Store the calla lily bulbs in a cool, dark, and dry location with good air circulation. The ideal storage temperature is between 35-45°F (2-7°C). Avoid storing bulbs in plastic bags, as this can trap moisture and lead to rot. Instead, use breathable materials such as mesh bags, paper bags, or cardboard boxes.
Humidity Control
Maintaining proper humidity levels is crucial for successful bulb storage. Too much humidity can promote rot, while too little can cause the bulbs to shrivel. Aim for a relative humidity level of around 60-70%. If necessary, use a hygrometer to monitor humidity levels and adjust accordingly.
Monitoring and Sprouting
Check the bulbs periodically during storage for any signs of sprouting or deterioration. If you notice any sprouting, move the bulbs to a cooler location or reduce the storage temperature. Discard any bulbs that show signs of rot or disease.
Planting in Spring
When spring arrives and the soil has warmed, it’s time to plant your calla lily bulbs. Choose a sunny location with well-drained soil. Plant the bulbs 2-3 inches deep and 4-6 inches apart. Water thoroughly after planting and keep the soil moist but not soggy.
Conclusion: Wintering Your Calla Lilies with Success
Preserving calla lily bulbs for winter is a rewarding endeavor that will ensure the continued beauty of these elegant flowers in your garden. By following the steps outlined in this guide, you can successfully store your bulbs and prepare them for a vibrant bloom the following spring.
