Tiny yellow spots on leaves
Roses don't normally get blackspots here so I bought this rose plant assuming that the diseases will all go away with some TLC. I thought it must have been the conditions (and overwatering) at the growing facilities that made it so prone to disease.
I see it has a minute amount of black spot. Ok, no problem, I can't ever remember seeing any roses in the neighborhood yards with black spot, so it will go away. The powdery mildew, I'm sure I can manage (I've wiped most of it all). But I wonder what are these yellow spots? Are they a precursor to black spot disease?
I tried searching for information on yellow spots to no avail. Is this something I should worry about or will it go away with some TLC?
