As the vibrant summer days fade and temperatures begin to drop, it’s essential for gardeners to prepare their Canna lilies for the upcoming dormancy period. Proper fall care ensures healthy growth next season and preserves the beauty of these tropical-looking plants.
Understanding Canna Lilies and Dormancy
Canna lilies are perennial plants known for their striking foliage and bright flowers. Native to tropical regions, they thrive in warm climates but require special care as temperatures decline. Dormancy is a natural part of their growth cycle, allowing the plant to conserve energy during colder months.
Steps to Prepare Canna Lilies for Fall
1. Stop Fertilizing
Cease fertilizing your Canna lilies by late summer. This helps the plant prepare for dormancy, reducing excessive growth that could be damaged by cold weather.
2. Reduce Watering
Gradually decrease watering to allow the plant to enter dormancy naturally. Overwatering in cooler weather can lead to root rot and other issues.
3. Cut Back Foliage
Once the foliage begins to yellow and die back, cut the stems down to about 4-6 inches above the ground. Remove all dead plant material to prevent disease.

4. Digging Up Rhizomes
In colder climates, it’s best to dig up the rhizomes after the first frost. Carefully lift the roots with a garden fork or shovel, taking care not to damage them.
5. Cleaning and Drying
Brush off excess soil and let the rhizomes dry in a warm, well-ventilated area for a few days. This helps prevent rot during storage.
6. Storage Tips
Store the dried rhizomes in a breathable container such as paper bags or mesh boxes. Keep them in a cool, dark place with temperatures between 40-50°F (4-10°C). Check periodically for mold or rot and remove affected rhizomes.
Additional Tips for Successful Fall Care
- Label your rhizomes to keep track of different varieties.
- Avoid storing in damp or humid environments.
- Start planning for replanting in spring once the danger of frost has passed.
- Consider mulching around the planting area in early fall to insulate roots.
By following these fall care tips, you can ensure your Canna lilies will emerge healthy and vibrant next season. Proper preparation during dormancy is key to maintaining their stunning appearance year after year.
