Hi Everyone. I’m wondering if this is RRD on my plum perfect. The many tiny thorns on this stem looks off.
If it is RRD is it ok to plant another rose in the same spot?
"RRV" was used here on the forums interchangeably with "RRD" until quite recently, when it became generally accepted that "RRD" was more correct and accepted among the wider scientific community. Technically, the RRVirus is the CAUSE of RRDisease. Since rifis is so adamant he's never seen "RRV" used, I suggest these threads:
RRV and here
And Seil, I knew you had mis-read my post. No harm done. But trust me, I'm probably more familiar with both RRD and RMV than most gardeners as owner of 110+acres riddled with invasive multiflora infected with RRV-or-D (whichever is more appropriate in that context); having lost more roses to RRD than I can count (or afford to replace); and having almost 70 out of 200+ roses in my garden originally grafted on Dr Huey (the source of almost all RMV).
Does not look like RRD, that is the correct foliage also. To answer your other question, yes you can just clean up any plant material and plant a new rose. I have lost 5 roses to RRD and they have all been replaced without any issues.

Knockout roses infested, what bug is this?
Thank you for your reply Dianela! The small thorns looked kind of odd so I wanted some help from the experts :)
What is RRD?
Ann, RRD is rose rosette disease. It is sometimes called RRV, rose rosette virus.
Fig-insanity: Thank you!
Dianela is correct. You have nice healthy robust new growth. Enjoy!
You are welcome. I am no expert, but I think this is just one of those diseases we are all on the lookout for around here. After losing several plants I made myself a routine of always looking for it in my garden. Removal at first sign is probably the safest bet to avoid major loses. I am glad your plant is healthy 😃it always breaks my heart when a rose gets it.
What are the signs & symptoms?
Only rose whisperers are privy to a rose’s symptoms, Ann.
Ann and Fig, RRD and RMV are two different diseases and are not related in any way. Rose Rosette Disease is a virus that is spread by a tiny mite that floats through the air, lands on a rose, bites it to feed and thus infects the rose with the virus. RRD is always fatal. The plants should be removed immediately upon discovery and destroyed. Do not compost! SOME symptoms are the very red AND distorted new growth and hyper-thorniness. Also larger canes growing out of skinnier canes but there are others. There are many articles devoted to this disease on the web.
RMV, Rose Mosaic Virus, was introduced into US roses back in the early 20th century when infected root stock was widely used to propagate roses for sale. As a result there are VERY FEW roses available today that are not virused. Even own root plants are virused because they were grown from virused cuttings. There is a heat treatment called indexing that can kill the virus in the plant matter. But virus indexed roses are few and far between and are more expensive. If you are buying a rose from a site and it does not say "Virus Indexed" then it probably has the virus. I'd bet money every rose in my garden has it. RMV is NOT FATAL! Most plants with RMV will live and grow and bloom beautifully for decades! Symptoms usually only show up when a rose is already stressed due to some other issue, like heat or drought. It is said that the virus may weaken some roses so that they do not winter as well. I have a 65 year Pinocchio, in Michigan where it gets real cold, that I know is virused that belies that! The main symptom of RMV is a yellowing, sometimes lightening shaped, pattern on the leaves. Otherwise you'd never tell the difference. You probably already have RMV infected roses in your garden and don't even know it if they have been well cared for.
Oh, Fig, OOOPS! I just reread your post and realize you said RRV not RMV! So sorry. But I think I'll leave my post because I think it still has good info for Ann. Sorry again!
Agree with leaving it, seil. Otherwise Ann might confuse RMV ( when she otherwise would have first heard of it) with fig’s “RRV”.
I wonder if “RRV” is a regional expression. I’ve not heard it nor read of it before, here in NJ.
What do youse ( you guys, y’all) think?
Thank you everyone for all the super helpful info... I so much to learn.
Thanks rifis! I do prefer RRD because RRV does get confused with RMV too easily and they are so very different.
Fig, thank you for understanding. You do have extensive experience for sure. I just get really crazy when people want to throw away perfectly healthy otherwise plants because they have a few yellow patterned leaves once in a while. The big problem is that people don't understand that nearly all roses sold here now have RMV and they don't even know it. They think that one rose, that for what ever reason, showed some symptoms is the only one virused they have and that it has to go! If I tossed every rose in my garden with RMV I'd have no roses!
Thank you everyone! I planted this rose last year and thanks to the deer I haven’t seen a bloom yet. I’m glad to hear that this is normal healthy growth and look forward to seeing it bloom!
The following was stated: "Most plants with RMV will live and grow and bloom beautifully for decades!"
H. Kuska comment: no citation is given. Perhaps this quote is applicable:
"I don't disagree with you at all, Kathy. I do buy grafted roses all the time. And I don't think being grafted causes a shorter life span. What I do think is that a lot of grafted roses are infected with RMV (Rose Mosaic Virus) and THAT does cause a shorter life span."
About planting a rose in the same spot. I read about Rose Replant Disease a while ago, so I was careful and didn't plant another rose after I lost a tea rose even though it was at a prime spot in my flower bed. But I saw people replacing a rose all the time. Just wondering if I was being over cautious.
