Are you familiar with "Rose Rosette Disease?" I have decided this is what my roses have. It started with the Knockouts last year. I noticed what appeared to be reddish new growth and lots of buds.

I do not see symptoms on the New Dawn, but have read that it is highly susceptible.
In the information I've read, the disease is thought to be spread by a virus and there is no known cure, but no one seems to have definite answers. It is believed to have started with the wild multiflora rose, which is an invasive plant imported from Japan. Until just recently, these were present in the lot next to our yard, so I am assuming that is where my roses contracted it.
I wonder how widespread it is in this area. I have not heard of anyone complaining of it yet, but I do not know a lot of "rose people." In other parts of the country it is a big problem.
I am not real upset over losing the roses, as I have enjoyed them for many years and am ready for a change. However, I am partial to the New Dawn and hope that it stays disease free. It is so beautiful in the spring.
