This rose bush was my Great Grandmothers (I'm 48 years old). I dug it up from my parents house in Florida because it was dying. It's gotten better here in the last year but is still so weak frail. Now these black spots! I need help! I don't even know what kind of rose bush it is... We've always called it "The Nettie Rose", that was my grandmothers name.
Can you help me?
