I have three scraggely roses in my yard that something is eating on. The leaves also have little white spots, yellow leaves, and black spots. They are all very scraggely too. I'm afraid to cut them because I don't know what I'm doing. What should I treat them with? Two of these only have one branch coming from the ground, if I cut that will it shoot off branches? What time of year should I do that? I just don't have a clue. I'm attaching a few photos under separate posts.
