Setina: Should I be worried?

A while ago we had huge winds and shortly thereafter I noticed a developing bud on Setina that looked thornier. I removed that lateral and decided to just remove the very large "mother" cane that had many laterals attached. However, I still wonder though about this newer recent growth that's only come about since I've treated it for severe midge. It's only its second year in the ground so it's still its "creep" year and this could just be a more mature growth habit. Judging from the following pictures, should I be worried? I'd rather remove it than endanger other roses, but I'd hate to jump the gun. Pics to follow once my phone cooperates.

    What a fabulous rose!

    Where have you been hiding this beautiful rose, Sheila? I swear I haven't seen any photos before of this one. I's just stunning. Diane

    What's my post a. A. I mainly worried about the thorns as there is no evidence of witches broom.

    I neither have nor know Setina.

    I see what concerns you, vaporvac. I would be on edge, too, and would be observing that rose closely, twice a day.

    Sheila’s note, if I understand what I think she meant to say, is reassuring, though.

    Vap, that doesn't look nearly thorny enough to be RRD. When I've seen it there were thousands of thorns packed so tightly together you couldn't see the cane. If it doesn't have any other symptoms I'd relax.

    I'll look at my thorns/prickles tomorrow Vapor. I'll get back here.

    Diane, I have had this rose among the Teas and it really can be adorable. ATM, my garden is not deadheaded, and needs a good rain. We also got 5 inches less of rain last Winter than the one before. I really need to get on it if the smoke ever leaves. Do a rain dance for me please.

    Sheila, I'll do a rain dance for you, if you'll do a rain dance for me (no rain here since May). I hope we all get mega rain, and the last of the fires are extinguished.


    Vapor, I don't know much about RRD, but that doesn't look like it to me. I agree with Seil. Diane

    Thank you all. Is there something else that could account for the selective hyperthorniness? I just found it strange in picture number 3 down to see the thornier lateral coming off the less thorny cane. Sheila, how long have you been growing Hermosa? I grow her also at Setina's feet.

  • 6 years ago

    I had the reaction you are having, Vapor, to a cane Munstead Wood grew last year. It was a thorny rubbery aggressive new growth that had me worried. I let it go and it turned out fine. Now I know MW can do that. Maybe Setina does that too.

    Vaporvac Z6-OhioRiverValley thanked Sheila z8a Rogue Valley OR

    Sheila, I, too, have noticed Munstead doing that sort of thing once in a while. It must be characteristic of certain roses. Diane

    Thank you Sheila. That is what I'm hoping to hear. Unfortunately so few people grow Setina but I'm hopeful that those that grow Hermosa will see this and respond. I probably should have put that in my original title.

  • 6 years ago

    Vapor, I looked for canes similar to your new cane but I do not have any new growth on this rose at the moment. My Hermosa is 4 years old from ARE. I am not saying much because I really cannot say I have noticed what Hermosa new growth looks like. I'll keep an eye out from now on. If we ever get rain, I might get new growth here. Of course, your climber could be different too.

    Thank you, Sheila. I'm keeping a close eye on it. I remember the new growth as a younger plant where the laterals grew like short little candles on a Xmas tree and I was thinking she might be low-thorn, but since I've tied her up, they have lengthened and grown pricklier. Hermosa is also getting large, but still has few thorns as a youngster.

    Regarding the soft thorns seen with RRD... do these ever harden up? I ask as those which were initially soft have hardened and don't look so packed as the laterals lengthen.. I'm hoping this might mean it's not infected. Why didn't I take a pic of what I removed??? ...Smacking head with palm. : ((

  • 6 years ago

    Vapor, I know the soft rubbery weird looking prickles on my MW did harden. The plant did not have RRD. I do not know if RRD rubbery prickles ever harden.

    I also have occasionally missed taking a photo that I really could have used. Too bad when that happens.

    Vapor - I found this:

    the main symptom of rrD is the ab- normal growth of congested clusters of stems called witches' brooms. ... Often, there is a prolifera- tion of thorns on the stems, but these do not harden like normal rose thorns. the virus eventually impacts the rest of the plant and ultimately kills it.

    So it sounds like it's not RRD!!!! Yay!!!


    Sheila - Your Hermosa is INCREDIBLE!!!! Oh Swoon!!!


    Oh...I found this that says they MAY eventually harden. Dang.

    Just thought I would post a few more pics from today. The first picture shows what I considered normal growth heretofore. The second picture that same sort of growth on the left came with what I consider new aberrant growth.


    Click to enlarge. This next picture shows abnormal Thorns that have now hardened.

    More posts to follow cuz I don't want to lose these.

  • 6 years ago

    This is New Growth that has elongated since yesterday and started growing thorns.


    I'm noticing that this growth is on new laterals coming out now. Again, quick to see full picture.

    So sorry, wish I knew. My sympathies, this waiting is so stressful. I kept my infected rose for a year and was lucky the RRD did spread.

    I wish I had new growth to compare, Vapor. Yours being a climber might look different too. I wish I could help more.

    I don’t have any idea about Hermosa or Setina, specifically, but I can add that I have one Excellenz von Schubert bush and he has some canes with zero thorns and some that are covered in little prickles. I only mention it as an example of another rose variety with canes with vastly different prickle levels on the same bush, so this might happen with other varieties too.

    So worriesome. I have no idea. Good luck, and hopefully everything is fine.

    Thanks everyone for the condolences. I can only write from one platform these days. And it's sketchy at best. Stephanie that is good news that EVS show something similar. It's just so hard to say since most folks post pics when the disease looks progressed. I often wonder how long they have been infected to get the typical witches broom. Here are a few more from today of the same growth.

    please click to see detail. The following was suspect growth that has matured a bit.



  • 6 years ago

    That last/bottom photo looks normal to me Vapor. Not having the climber is a handicap as far as advice, sadly.

    Thank you so much. That last pic is what I consider normal growth. I dont know what to do. It's hard to get a good pic.

  • 6 years ago

    I think your pictures are good, but I don't know if Setina normally does what yours is doing, if you know what I mean, in the other photos you are worried about. You might be the only one growing it here. When this happened to my MW, I think I posted about it and nobody said anything either. :-(

    Carol, I also wanted to thank you for that linked to the Oklahoman article on RRV. it was excellent and had several points I had not read before such as spraying dormant oil and hard pruning. My roses do not look anything like those pictured, but they have not set bud either so I can't make a judgment there. However, it mentioned a couple of things which I can check. Thank you again.

    Vaporvac - Oh! You're most welcome!! I'm so glad if I helped in any way!! :) :)

    I just read the RRD Management section...that is really helpful, I think. I didn't realize that removing the entire rootball is necessary...and waiting a few months to make sure the rose doesn't regrow.
