Aquilegia McKana - deadhead?
Hopefully one of you experts can advise! My Aquilegia McKana were planted last year as bare root and did well. This year the flowers are about 4ft tall and some have gone over with the recent heavy rain. At what point should I deadhead and how? Should I wait until all the petals have dropped, just start dropping, 50% dropped? And do I cut the whole flowering shoot back to the base or just cut off the flowers? Will I get more flowers? All the videos I have found deal with much smaller varieties that don't look like mine
