by

The Canna lily is a stunning tropical plant known for its vibrant flowers and lush foliage. Proper harvesting techniques are essential to ensure the health of the plant and to maximize the quality of the bulbs for future growth. This article explores effective methods for cutting and storing Canna lilies after the blooming season.

Timing of the Harvest

The best time to harvest Canna lily rhizomes is in the fall, after the plant has finished blooming and the foliage begins to die back. Waiting until the foliage has yellowed and withered ensures that the plant has stored enough energy in its rhizomes for the next growing season.

Techniques for Cutting

Careful cutting of the Canna lily is crucial to prevent damage to the rhizomes. Follow these steps:

  • Use clean, sharp garden shears or a spade to dig around the base of the plant.
  • Gently lift the clump from the soil, keeping the root system intact.
  • Remove excess soil by brushing it off gently with your hands or a soft brush.
  • Cut back the stems to about 2-4 inches above the rhizomes to prevent disease and rot during storage.

Storing the Rhizomes

Proper storage conditions help preserve the rhizomes for the next planting season. Follow these guidelines:

  • Allow the rhizomes to dry in a cool, shaded area for a few days to prevent mold.
  • Cut the rhizomes into sections, each with at least one eye or bud.
  • Place the sections in a breathable container such as paper bags or mesh boxes.
  • Store in a cool, dark, and dry location with temperatures between 40-50°F (4-10°C).
  • Check periodically for signs of rot or pests and remove affected sections immediately.

Additional Tips

To ensure healthy growth in the following season, consider the following tips:

  • Label stored rhizomes to keep track of varieties.
  • Avoid storing rhizomes in airtight containers to prevent moisture buildup.
  • Replant the rhizomes after the last frost date in your area.
  • Apply a balanced fertilizer during planting to promote vigorous growth.

By following these techniques for cutting and storing your Canna lily rhizomes, you can enjoy their stunning blooms year after year. Proper care during harvest and storage ensures the health and vitality of your plants for many seasons to come.
