I’m sorry, I am having a hard time understanding what “Pruning to an open (bowl?) shape…” means. Could you perhaps guide me to so info?
I have a book of rose care but I don’t see this…

If steam's have black spots do they need to be cut off?

[@maipham-qo8lt]

did that,still came back with black spots

After picking off the infected leaves, would they benefit from a light spritz bath of dilluted castile soap with distilled water? Or is that pointless😂
