Garden question! (rose bush) (louisville ky)
I have a spreading rose bush, I think it is a Scarlet as I remember. It has developed some really odd looking branches. At first I thought it was a weed growing up through it, but nope, it really is attached to the bush.

@David B: If you catch the disease very early on, and completely remove the affected cane, some experts say you might be able to save your rose. Otherwise, you have no choice but to remove the plant. (And it should be sealed in a plastic bag and sent to the landfill, not put on the compost pile.)
There's good information in this article from the American Rose Society: ...»

good portion of the dirt at the site. Sterilize any tools used on the bush as well.
Beware, damage by herbicides (Round Up or lawn weed killer) can resemble RRD. Before sentencing your roses with weird growth to be dug up and thrown away, ask yourself if there's a chance that anyone has used herbicide in the vicinity.
@Shannon, there's no need to remove any soil from the site of this rose when it is dug out. RRD is not soil borne. It is carried in the diseased plant itself. ...»
To dispose of this, cut the above ground portion of the rose off and bag or burn them. Dig up as many of the roots as you can, to prevent it from sprouting back from any roots left in the soil. When I have RRD in my rose garden, I wait for a few months before replanting, to make sure that the diseased rose is truly gone and doesn't resprout. In fact, I have a spot right now where one is attempting to regrow ... I must have missed a root when I dug it out this spring.
This bush is huge about 7-8 feet in diameter.
