Someone told me that cannas should be deadheaded after the bloom begins to fade. I don't understand. Doesn't one just cut the bloom off at the bottom of the bud? Thanks for instructions.
I like to deadhead the Canna Lily flowers after they have faded. It keeps the garden and plant more tidy and will promote more flowers.
You do need to be careful and cut the spent flower stalk down directly above the next flowering node which is just opening.
Repeat this with each fading flower.
