|Canna Lily 'Tropicana' picture obtained |
Q. Dead-heading canna lilies seems to work but results in the stalk getting very high and less stable as the flowers become smaller. At times I'll cut the stalk off at it's base if the leaves start to lose color or get wind-tattered but the plant may get really thinned out especially as winter approaches. Is there a best way to dead-head canna to get maximum flowers?
A. It sounds as if you're doing it correctly. As the individual flowers fade or are spent, twist them off of the flower stalk. Some flowers will be smaller than others. Dead-heading flowers doesn't necessarily mean the flowers remaining on the stalk will get a lot bigger. It does conserve energy for the entire plant so the number of flowers or the relative size will increase overall and help conserve energy for growth and flower production in future years. You were still going to see a difference in flowers size among the flowers on a single stalk. As the flower numbers in size and no longer serve you, then remove the entire stock at its base.
By the way, canna lilies very well in our desert climate and add a touch of a tropical feeling to any landscape design.
