BarryBoyd said:I have had RRD in three of my bushes previously - a red carpet rose, a chestnut rose, and a R. multiflora.

I detected RRD in the carpet rose when it only affected one cane. I cut that cane to the ground and RRD never reappeared in that bush. I kept an eye on it for the next three years before I moved.

I detected RRD in the chestnut rose when it affected about 1/3 of the bush. I cut the entire bush back to the ground and the rose came back from runners it had sent out and those runners were unaffected. In fact, I transplanted one of the runners to my new house and it has been in fine health for the past six years.

I detected RRD in the multiflora when almost the entire bush was affected. I cut it down to the ground and hit the stump with roundup. It was not worth trying to save.

At the time, I had over 400 rose bushes (I'm now down to 160). Trying to save the affected plants did not cause a major outbreak in my garden. Your mileage may vary.

If that was my New Dawn, I would cut all affected canes to the ground and see if the problem goes away. If it doesn't, you can always dig it out later.

Very helpful, thank you and thanks to everyone who posted links as well.

I had read the e-book and about everything I could find, but thought it just seemed extreme to destroy a bush this old and don't have the heart to do it. It's obviously been cut back drastically, but we've cut it back that harsh before.

Took several cuttings to try as well. We have a few spots on our property that are downwind and overgrown so we may try a new one there just in case the it comes back sick next year.

Either way, aside from cleaning up the base and figuring out how to get that tree out of the middle, we're leaving it alone for this year. Will be interesting to see how it does next spring however as it will have gotten more TLC this year than it has in the past 20.
