RRD - witches broom? Knockout roses

Posted by CharNC 7 (My Page) on

Can any identify if this is RRD? About 25% of the bush has this in it. We are located in NC if that matters. None of my other roses are showing signs but they are spaced pretty far part and this is my only knockout.

Thanks for the help.

Geesh--each pic got worse! By the third pic, I was ready to pronounce this rose a victim of RRD. Destroy it immediately before it can cause harm to any others (RRD mites getting borne on wind currents around your yard).

So sad!


RE: RRD - witches broom? Knockout roses

The first two I wasn't sure. But the third definitely looks like RRD. And if it's over 25% of the bush, you have no choice but to dig it up and dispose of it.

The look of the rose buds is the give away for RRD on these bushes. Healthy Knockouts have simple hardly ornamented sepals. The sepals on these blooms are horrifically overgrown and aberrant.
