Q.Rose Rosette disease affecting knock out roses
Need to speak with someone about above problem. I have sprayed the roses,but, they look horrible. Do I dig up all of them. Not positive that this is the disease that they have but from what I’ve read and seen, it seems it may be.
Thank you.

If you correctly identify it with Witches Broom, it should be removed.
