Calla lilies are a popular and elegant flowering plant that can be propagated through their rhizomes. Harvesting these rhizomes correctly ensures healthy growth for future planting seasons. This guide provides step-by-step instructions on how to harvest calla lily rhizomes safely and effectively.
Understanding Calla Lily Rhizomes
Rhizomes are underground stems that store nutrients and produce new shoots. In calla lilies, these rhizomes develop annually and can be divided and replanted. Proper harvesting at the right time is crucial to ensure the rhizomes remain healthy and vigorous for future growth.
When to Harvest Calla Lily Rhizomes
The ideal time to harvest calla lily rhizomes is in the fall after the plant has finished blooming and the foliage begins to die back. This period typically occurs several weeks after flowering. Harvesting during dormancy minimizes stress on the plant and allows the rhizomes to store energy for the next growing season.
Signs that indicate it’s time to harvest
- The plant’s foliage has turned yellow or brown.
- The plant has stopped producing new growth.
- The soil around the plant is dry and crumbly.
Tools Needed for Harvesting
- Garden spade or shovel
- Garden fork
- Pruning shears or scissors
- Gloves
- Clean bucket or wheelbarrow
Step-by-Step Harvesting Process
Follow these steps to harvest calla lily rhizomes properly:
Prepare the Area
Clear the area around the plant. Remove any debris or weeds that may interfere with digging.
Dig Carefully
Use a garden fork or spade to gently loosen the soil around the base of the plant. Dig deep enough to expose the rhizomes without damaging them.
Extract the Rhizomes
Carefully lift the rhizomes from the soil. Use pruning shears to cut away any damaged or diseased parts. Handle the rhizomes gently to prevent bruising or breaking.
Clean and Dry
Remove excess soil by rinsing the rhizomes with water. Allow them to dry in a cool, shaded area for several days. Proper drying prevents rot during storage.
Storing Calla Lily Rhizomes
Store the dried rhizomes in a cool, dry, and well-ventilated space. Use paper bags or mesh containers to prevent moisture buildup. Label the containers with the harvest date for future reference.
Tips for Successful Harvesting
- Harvest during dry weather to avoid excess moisture.
- Handle rhizomes gently to prevent damage.
- Inspect rhizomes for signs of disease or rot before storage.
- Divide large rhizomes to promote healthy growth.
By following these guidelines, you can ensure a healthy harvest of calla lily rhizomes that will flourish in your garden year after year. Proper harvesting and storage are key to maintaining a vibrant and beautiful collection of calla lilies.
