Here is a picture of a new canna this year for me to grow. canna Cannova red shades It has been developed to go into containers and it looks awesome. I have a question about taking off the spend part of the bloom. So here is what I found out.
Canna Cannova 'Red Shades' is a dwarf growing Canna with green foliage and deep red flowers. Plants will grow between 3 to 4 feet tall and flower all summer.
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. To do this, cut off the spent flower stalk directly above the second flowering node, which should be just opening. Usually a single canna has several flowers blooming in different stages. Continue to prune off the spent flowers, leaving the ones that have are just opening or have budded. Now that is what I will do before the fair.
