The causal agent of rose rosette disease is not soil- borne, so it is possible to successfully plant healthy roses in beds where diseased plants have been removed. However, because the pathogen is systemic in infected plants, the virus may persist in RRD-infected root pieces that remain in the soil.

As a result as long as the entire root system has been removed immediate replanting of a virus free rose should not result in infection. There is also no evidence that infection can occur if the root system of an uninfected plant comes into contact with an infected plant.

I had my infected Knock out roses removed last fall along with ( hopefully ) all root system, when is it safe to replant in that flower bed and with what kind of plants. Do you recommend spraying with Clorox? Thank you

In reply to joe.

Dear Joe,
Sorry to hear of the lose of your rose, hopefully you caught it before it spread to any others you have in the garden.

After reading this post I realize that my friend of the last 6 years is infected with RRD. I live just north of Nashville and this appeared for the first time recently. (couple of months ago). Sure did spread quickly. Taking it out tomorrow.

Still looking for Judy Penney to discuss more on this subject. I wiped out her email address when I got a new computer evidently, but would love to be in touch. So would a journalist who is writing an article for a local Princeton Paper.

The best thing you can do to protect your remaining rose bushes is to remove the infected plant and any leaves or debris on the ground adjacent to your healthy roses.

Today I noticed what I suspect to be RRD on one of my double knockout roses I had planted last spring. I plan on digging up & destroying the plant tomorrow. Is there anything I can do to protect the remaining rose bushes?

Debbie,

You should remove your plant and destroy it to prevent the RRD spreading to other plants.

I had a beautiful double knockout rose bush that has been envy of neighbors. I started cutting it back on Sunday because it had grown so much. I don’t know how long it has had RRD but it has looked strange for a while. I thought it might be a fungus until I started reading. I live in western NC in the foothills. ????

I only have 3 rose plants. My 2 knockouts had this disease for several years and I just though it was a weird mutation. I have now removed the roses and won’t be planting knockout or any other roses in the area. I was hoping to save my climbing Zephirine. No luck, it is now infected as well. I will have to remove. I will try to remove all bits of roots and plant another. I only had the vine 3 years, but this was the first year it bloomed. I was so excited to see the blooms on my shady side of the house. I didn’t notice the disease until a month ago, but it is really taking over fast. Very frustrating, but I really feel for the owners of really old special roses. Very heart breaking. I know several other friends in my area that have the same problem with their knockouts. This is really a serious problem, I hope someone can find a solution soon. I live just north of Nashville.
