LOL Neal, I may have to find the "Typhoid Mary" in my neighborhood.
I have one neighbor across the street with Knockouts, and my neighbor next door put in a bunch of roses, over 20, that he bought from Lowes in the past year on sale. He planted them in red clay soil with no amendments or fertilizer, so I'll have to see if his plants are diseased. Of course, his plants aren't doing well.
I have a few Knockouts that look fine, and my other roses are fine as well, with no signs of RRD.
