I am posting for my mom, who is seeing something odd on a few of her Knock-Outs.
A bud forms, grows, and before it opens it sends out leaves on the bud, then they dry and drop.
She writes:
"Sometimes a branch on one of the knock-out rose bushes will get flower buds that look like they are going to open up, but they start getting covered with dark red, frilly, leaf-like growths. They never do open and eventually just turn rusty and dry up. Sometimes all the branches on the bush do this. Sometimes just one or two branches do it. The branch in the picture below was the only branch on the bush that was affected. Note the fading, normal looking blooms."

Any clue what is going on?

If the growth is red, thorny, and "wild" looking, it could be the beginnings of Rose Rosette disease.

Thanks- we were completely unaware of this disease and are now terribly saddened.

Yes this is ROSE ROSETTE DISEASE.
You need to remove the infected plants before you will lose all you other roses.

Does anyone have an idea howlong it takes the soil to recover from RRD once an infested bush(s) is removed? Is it a matter of years?
Thanks!
