My Dublin Bay Climbing Rose Is Suffering

Question

My Dublin Bay some 7 years old is struggling. 2 years ago I cut out some what appeared dead or dying wood. last year it started to recover but grew strong long sucker like stems with the blooms on the top. each stem has the standard 5 leaves looking normal but no growth on long stems until the top. See images.Question, are these long stems appearing suckers and why have I so many onion type growths on the main stems.

Answer 1

Repeat flowering climbing roses need to be deadheaded often to keep them blooming well. Yours needs a lot of corrective pruning, i.e., remove the dead, damaged, and crossing stems. I believe the knob with several stems emerging is a graft. Canes coming out below the graft can be removed.
