Do Canna Lilies Rebloom

How to Grow Canna Plants. In planting zones 8 and up, cannas will repeat-bloom throughout summer, and throughout the year in zones 9 and above.

How many times does a canna lily bloom?

Cannas easily bloom all summer without much effort. But for those of you who want to give your plants an extra boost, apply a 5-10-5 or 10-10-10 in the spring and, if you wish, two more times during the growing season.

Do you deadhead cannas?

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.
