How to treat black spot on roses  

Thank you

Thanks

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?

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😂
