Rose Rosette

Two of our rose bushes have succumbed to Rose Rosette.  I've researched the virus online and understand that there's nothing we can do to try to save the bushes. We have five other rose bushes that do not show any signs of  it.  Has anyone else has dealt with Rose Rosette and if so, did you end up losing all of your roses? 

I have not, and nor had I heard of anyone locally who'd yet encountered it.  Sorry about your roses! I think if you catch it early and mites have not yet spread the disease, your other plants should be fine. Good luck.

@iwasmim - thanks for your feedback.  It's nice to know rosette is not common around here.  The arborist from SavATree is coming on Wednesday.  I'm pretty sure it's rosette, but it'll be good to get a second opinion before I pull out the bushes. It seems the more I try to care for our plants, the more they end up being struck down by pests, blight, viruses, etc.  

Actually if I recall correctly, someone posted about this affecting their rose bushes last year.

So it does seem some in town are affected. I wonder if my one rose bush has it, but I can't tell.

Hi, Sadly I started that thread.  It is real, it is here and so far?????

Our arborist said that there was nothing to do but pull them out and burn them.  That was two years ago.

They are growing again this spring and I'll report on how they look.  All the symptoms are present:   Hairy thorns on the stems.  Dark red overgrowth of leaves and less bloom.  Will report as spring progresses.   He told me we could keep them for several years to see...  That's what we decided.

Best Regards,

We are open on May 7 for $7 a person or a Garden Conservancy ticket.  You can come look.

@rcarter31:

Does your garden rose collection currently feature any non KO's; if so, were any (or all) afflicted w/RRD last year?

I googled rose rosette (I have two rose bushes that I recently transplanted to my mother's yard in the hopes of saving them from neighborhood cats) and apparently this disease is often carried by multiflora roses. What I didn't realize was that multiflora is an invasive species. My mom has one in her yard. Should I hack it out? It is a good 20' away from the transplanted roses, so there is no danger of contact between them.    

@rcarter31 - thank you!  I will come over on May 7th and take a look.  Look forward to seeing you and your lovely garden.

@spontaneous - I wouldn't hack out the multiflora unless it shows signs of the virus.  I think multiflora is very susceptible to rosette, but it can strike any rose.  I don't know enough about roses to tell you what kind we have.  Two of our bushes are infected and they are at least 100 feet apart (on opposite sides of our house).

If it was only contact  ...  RRD is not like a mammalian venereal disease; would be nice if it was.

There's invasive, and there's noxious invasive - multiflora is the latter.

Roses saved from cats?  should be the other way around. Are they thornless?

They are not thornless.  Neighborhood cats decided that the mulch underneath my roses made a good litter box.  Apparently the thorns did not deter them from doing so.  I tried cat-away spray, lemon rinds, moth balls, voodoo spells, you name it.  The cat-away spray was so noxious that I could smell it from inside the house.  Nothing worked.

Management of Rose Rosette Disease
Poster Number: Tuesday, August 09, 2016
08:30 AM - 08:45 AM
Sheraton Hotel Atlanta
- Capitol North Room
Rose rosette disease (RRD) has been responsible for the destruction of 10’s of thousands of roses in commercial and private landscapes throughout the Mid-South.  The only management strategy has been to destroy symptomatic plants and many of the plants were not destroyed until large rosettes developed in the infected bushes.  For four years we looked at pruning at first symptom detection of RRD, using a green barrier to impede movement of the vectors, preventative miticide sprays and rogueing at symptom detection.  Pruning out symptomatic foliage was ineffective for reducing RRD symptoms from emerging on other canes.  Green barriers (1.8-2.1 m plants of Miscanthus sinensis) reduced incidence of RRD in test plots by more than 50%.  Plants sprayed on 14 day spray intervals with Akari, Forbid, Kontos or Talstar did not develop symptoms of RRD whereas all plants sprayed with water (control) were symptomatic for RRD by the end of year three.  Monitoring roses daily for RRD symptoms and rogueing of plants at first detection of symptoms prevented plants less than 1 m away from becoming symptomatic for RRD. authors

No rose gardens downwind from the secret garden?

In addition to the two transplanted roses mentioned above I planted third rose. The other day when watering them I noticed some red leaves one one of the two original transplants, and further inspection shows the stem having too many thorns. It doesn't yet look like the classic pictures, but I fear it is the early stages of the disease. None of mine are KO roses, they are Griffith Buck roses.

Also, there is an office building up in WO that has rose rosette at their entrance. I happen to be there on a somewhat regular basis, so I spoke with the woman who coordinates and she said she would inform the grounds crew. All they did was trim back the bushes, but they are still there. So I'd say that rose rosette is taking a foothold in Essex county, and we will be seeing more.
