Why Dig Up Calla Lily Bulbs?
Calla Lilies, native to warmer regions, aren’t naturally equipped to handle freezing temperatures. In USDA hardiness zones 7 and below, digging up the bulbs (technically rhizomes) is crucial for their survival. This process allows the rhizomes to enter a proper state of dormancy, preserving their energy for the next growing season.
If your winter means freeze, snow and cold, your outdoor Calla Lily would certainly need intervention
For those lucky gardeners in zone 8 and above, your Calla Lilies can typically overwinter in the ground with some added protection. A layer of mulch can provide insulation, but remember to leave a small gap around the stems to prevent rot.
When to Dig Up Calla Lily Bulbs
Timing is crucial when it comes to digging up your Calla Lilies. The ideal moment is shortly after the first frost has caused the foliage to die back, typically in late fall. This ensures that the plants have stored up enough energy to survive their winter dormancy.

Using a garden fork, gently lift the Calla Lily rhizomes from the soil. Take care not to damage them in the process.
2. Remove Excess Soil
Brush off loose soil from the rhizomes using your hands or a soft brush. Avoid washing them, as excess moisture can lead to rot.
3. Inspect for Health Issues
Examine each rhizome carefully for signs of disease or damage. Discard any that show rot or other problems to prevent spread.
4. Trim the Foliage
Using clean, sharp pruning shears, cut back the remaining foliage to about 2-3 inches (5-7.5 cm) above the rhizome. Make angled cuts to discourage water pooling.
5. Cure the Rhizomes
Allow the rhizomes to dry in a warm, well-ventilated area for 4-7 days. Aim for temperatures between 65-75°F (18-24°C). This curing process toughens the outer skin, improving winter survival rates.
6. Prepare for Storage
After curing, wrap the rhizomes in newspaper or place them in paper bags. Choose a cool, dry storage location with a consistent temperature around 50°F (10°C).
7. Monitor Throughout Winter
Regularly check your stored rhizomes for signs of sprouting or decay. If you notice any issues, trim away damaged areas and apply a fungicide if necessary.
Tips for Successful Winter Storage
- Maintain good air circulation around stored rhizomes to prevent moisture buildup
- Never water dormant rhizomes – they don’t need it and excess moisture can cause rot
- If storing multiple varieties, label them clearly to avoid confusion in spring
