I am a beginner in terms of gardening but enjoy it immensely and am new to this forum so grateful for any help and advice.
I love roses and have planted three or four types in my garden. The white roses often end up with black spots on the leaves.
I also have some beautiful red roses which have just started blooming, but they have white spots on them and look pretty awful.
I have no idea what us causing the problems or how to treat them so any advice would be most grateful.
I've attached a couple of photos.
