Should Cannas Be Deadheaded

Deadheading is another way to prune cannas. Rather than cutting the canna back to the ground, deadheading means removing the spent flower blossoms. This allows the plant to put more energy into producing new blooms rather than going to seed. Cannas should be deadheaded on a continual basis to encourage re-blooming.

How do you keep cannas blooming?

For best blooms, plant cannas in full sun, water regularly and fertilize plants 2-3 times throughout the growing season with a general 10-10-10 fertilizer. The most common reason for no flowers on a canna plant is overcrowding. When grown as perennials, canna lilies will grow and spread very quickly.

Should you remove seed pods from canna lilies?

Answer: Leaving the seed pods on canna plants to pop open and grow more plants could be fun but it is not necessary. If you want to give seeding a try wait until the pods turn yellow to brown. Then remove the seed, nick them and sow them in a potting mixture covering once their thickness.
