Calla lilies are beautiful and elegant plants that produce stunning flowers. Many gardeners enjoy growing them not only for their blooms but also for their bulbs, which can be harvested and stored for future planting. Proper harvesting and storage of calla lily bulbs ensure healthy growth in subsequent seasons.
When to Harvest Calla Lily Bulbs
The best time to harvest calla lily bulbs is in the fall, after the plant has finished blooming and the foliage begins to yellow and die back. This indicates that the bulbs have matured and are ready for removal. Avoid harvesting too early, as immature bulbs may not store well or produce healthy plants next season.
How to Carefully Dig Up the Bulbs
Use a garden fork or spade to gently loosen the soil around the calla lily plant. Carefully lift the plant, ensuring you do not damage the bulbs. Shake off excess soil and inspect the bulbs for any signs of disease or damage. Healthy bulbs should be firm and free of mold or soft spots.
Cleaning and Preparing the Bulbs
Remove any remaining soil from the bulbs by brushing gently with a soft brush. Allow the bulbs to air dry in a warm, dry location for a few days. This helps prevent rot during storage. If the bulbs have any damaged or rotting areas, cut them away with sterilized scissors.
Storing Calla Lily Bulbs
Store the dried bulbs in a cool, dark, and well-ventilated space. Use mesh bags, paper bags, or crates to allow air circulation. Keep the storage environment at a temperature of about 50°F (10°C). Avoid storing bulbs in plastic bags, as moisture can cause mold and rot.
Additional Tips for Successful Storage
- Ensure bulbs are completely dry before storing.
- Check stored bulbs periodically for signs of mold or rot.
- Label the storage containers with the planting date for future reference.
- Replant bulbs in early spring after the danger of frost has passed.
By following these steps, gardeners can enjoy healthy calla lilies year after year. Proper harvesting and storage are essential for maintaining the vitality and beauty of this elegant plant.
