Calla lilies, with their elegant trumpet-shaped flowers, add a touch of sophistication to any garden. However, these tender perennials can be susceptible to cold temperatures, making it essential to provide proper care during the winter months to ensure their survival and continued beauty.
Prepping Calla Lilies for Winter
1. Dig Up Corms:
As temperatures begin to drop in fall, carefully dig up the calla lily corms. Use a garden fork or spade to gently loosen the soil around the plants, avoiding damage to the corms.
2. Clean and Dry Corms:
Remove any excess soil from the corms and gently rinse them with water. Allow them to air dry in a warm, well-ventilated area for several days.
Storage Options
3. Cool and Dry Storage:
Place the dried corms in a paper bag or cardboard box lined with newspaper. Store them in a cool, dark, and dry location with good air circulation, such as a basement, garage, or shed. The temperature should be maintained between 40-50°F (4-10°C).
4. Refrigerator Storage:
Alternatively, you can store calla lily corms in the refrigerator. Wrap them in a slightly damp paper towel and place them in a sealed plastic bag. Store them in the crisper drawer at a temperature of around 35-40°F (2-4°C).
Monitoring and Care
5. Check Regularly:
Inspect the corms periodically during storage. Discard any that show signs of rot or damage.
6. Keep Moist:
If storing in a cool and dry location, occasionally mist the corms with water to prevent them from drying out.
Replanting in Spring
7. Prepare the Soil:
When spring arrives and temperatures rise, prepare the soil for replanting. Amend it with organic matter, such as compost or manure, to improve drainage and fertility.
8. Plant the Corms:
Plant the corms with the pointed end facing up and the roots down. Space them about 6-8 inches apart and 2-3 inches deep.
9. Water and Fertilize:
Water the corms deeply after planting and fertilize with a balanced fertilizer.
Additional Tips
- Choose hardy calla lily varieties that are more tolerant of cold temperatures.
- Mulch around the calla lilies in fall to provide insulation and protect them from frost.
- If you live in an area with severe winters, consider growing calla lilies in containers that can be brought indoors for the winter.
- Overwintering calla lilies in a greenhouse or cold frame provides optimal conditions and increases the chances of success.
Recommendations:
By following these comprehensive instructions, you can successfully keep your calla lilies over winter and enjoy their stunning blooms season after season. Remember to provide proper storage, monitor their condition, and replant them in spring to ensure their continued health and beauty in your garden.
