I have the same problem with a Madame Alfred Carriere climber. This is against a wall with a Warm Welcome
climber 9ft away on the same wall, same soil, same sun. The Warm Welcome is just fine with lots of flowers.
The Madame Alfred Carriere is very healthy with good vibrant green growth but no flowers. It is a mystery.
By the way, how do you identify a blind shoot? Is every piece of new growth/new branch a potential blind shoot?
