Leaf damage on rose bushes?

Asked April 29, 2020, 8:27 PM EDT

From 3 different types of rose bushes have yellow & green leaves. I thought that was just their coloring, but now I'm wondering if this is bad?

I would suggest a soil test surrounding the bush to see if you are missing something before applying any amendment. While blackspot is normally not a problem, if these bushes are in the shade is is a possibility.
