Cannas grow on rhizomes, and like most rhizomes plants, they need to be cut down to the ground once the plant is done actively growing. The best time to do this is a few days after the first hard frost of fall. The frost kills the aboveground parts of the plant. Let them dry out, and then prune them.
How do you cut back canna lilies for winter?
Cut the leaves and flower stalk at the soil line when the plant dies back after the first frost. Use a knife or a pair of sharp clippers to cut through the fleshy stalks. Stop fertilizing in winter to allow the canna plants to go dormant. Spread a 4- to 6-inch layer of mulch over the soil above the roots.
What do you do with canna lilies after they bloom?
After the flower stem has been deadheaded several times and is no longer producing flowers, cut the flower stem and any attached foliage to the ground, as this can help nearby cannas get more light and flower themselves. (If you prefer, just cut the stem back to the foliage, which will last until the first frost.)
