When it comes to storing canna bulbs, it is generally recommended to cut off the roots before storing them. This is because leaving the roots intact can increase the chances of rot or fungal diseases developing during storage.
To begin the process, I typically leave a stub of the stem attached to the bulb. This helps me identify the top of the bulb when it comes time to replant them. Once I am ready to store the bulbs, I carefully cut off the stems, making sure to leave a short stub.
Next, I gently dig out the roots from the soil using a garden fork. It is important to be cautious during this step to avoid damaging the rhizomes, which are the thickened underground stems of the canna plant. I find that lifting the bulbs with the garden soil still attached is beneficial.
Leaving the garden soil on the rhizomes until it dries out helps to create a protective barrier against moisture and potential pathogens. This can be especially important if you live in a region with high humidity or frequent rainfall. Once the soil has dried, the bulbs can be stored in a cool, dry place.
By cutting off the roots and allowing the soil to dry before storage, you can help prevent rot and fungal diseases from affecting your canna bulbs. This will increase the chances of successfully storing and replanting them in the future.
In my personal experience, I have found that following these steps has helped me successfully store canna bulbs over the winter months. By taking the time to properly prepare the bulbs for storage, I have been able to enjoy healthy and thriving plants when it comes time to replant them in the spring.
To summarize, cutting off the roots of canna bulbs before storing them is generally recommended to prevent rot and fungal diseases. Leaving a stub of the stem attached to the bulb helps with identification during replanting. It is important to be gentle when lifting the bulbs to avoid damaging the rhizomes. Leaving the soil on the bulbs until it dries out can provide a protective barrier against moisture. Storing the bulbs in a cool, dry place will help ensure their viability for future planting.
