Normal growth on roses, or something else?

6 years ago

Hello!


I've been noticing some odd-looking growth on a few roses; the first two are of Earth Angel, last couple are from Princess Alexandra. The bushes are about 30 ft away from each other. Bright pink thorns have been around since March on PA, and I'm just begnning to notice some distortion in the leaves. Normal, or early signs of something else? Very grateful for your input!

    Looks like basal shoots to me. One of my roses just had 2 vigorous basal shoots that are much longer than other branches and now have multiple buds on them. I plan to cut them back after they bloom.

    It's hard to say from the pictures, but .....

    The first pictures look like they might be Rose Rosette Disease. Particularly if the cane is larger in diameter than the cane it comes from.

    The second ones don't look noticeably abnormal, unless the cane has stayed red longer than other roses in the neighborhood. Given the on/off nature of spring this year, many things are just maturing late.

    @ sbrklyn_7bny I hadn't even considered basal shoots! Went to check, it's not connected to another stem, and appears to be a basal shoot.

    @ mad_gallica Sorry about the photos, they are indeed not the best. I'll post some new ones below.


    Thank you, everyone!

    Looks like normal growth to me. Weather has been so weird everywhere I think we are all going to see some odd things in the garden this season. I have poppies ready to bloom before my iris have opened. Some of my daffs are still blooming when all my tulips are done. Lots of weird things going on out there.

    I thought the same as what mad_gallicasaid- that it could be Rose Rosette Disease-BUT only if they are getting distorted & knarly & weird looking, because this time of year fresh new leaf growth on some roses look rosy also.

    Most of your photos look ok to me from what I can see. I wouldn't cut it off until I saw sure signs, and then I'd cut it off and bag it and wash my clippers really well, because I heard it's caused by a virus.

    Also I see you are zone 6a and I'm in zone 6b and a couple of those really cold nights recently seemed to be harsh on my New Dawn Climbing Rose, so a mild frost bite maybe?


    Right now all of my Rose Munstead Wood have really pretty red leaves and it's not that disease. I've seen Rose Rosette Disease attack roses at a neighbors house and it is distinctly odd looking in texture and form, and really looks "wrong".,and yes it's red but not healthy looking growth.

    There is a good photo on this link:

    "Virus transmission occurs most readily between the months of May through mid-July when plants are making active growth. Symptoms from new infections usually start appearing in mid-July. In general, smaller plants go through the disease stages more quickly than larger plants. source-http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/diseases/viruses/rose-rosette.aspx

    Hope that helps.

    @Sue Hughes Zone 6b in Pittsburgh Your Munstead Wood looks lovely! Thank you so much for the info and links, and I'm so sorry for your neighbor's shrubs. I think you may be correct re: the cold spell (which we likewise had/is ongoing in my corner of KS), and also re: the information that RRD seems to show up in mid/late summer.


    I will also look into sending K-State's office a sample; apparently they are still open and running diagnostics.

    SamuellaZ6a, good luck with your roses!

    Looks like brand new, wonderfully growing basil shoots to me - congratulations!

    I'm new to growing roses, can anyone tell us all about basil shoots?

    Are they the shoots that get rose buds on them? How does one prune them? do they come out of the base of the plant or up. Do all types of roses get them or just Tea Roses?

    I was reading this link https://library.wur.nl/WebQuery/wurpubs/24129 and it was pretty heavy reading...I'm hoping for some one to give a simpler easy explanation.

    Thanks!

    Basals are new shoots from the base of the plant. They are great to see. Do not prune them. Let them flower.

    Would anyone be open to sharing other examples of basal shoots on their roses, and what the buds (particularly the sepals) look like? The growth on my shrubs indeed seems to be coming from the base of the plants (not growing off another stem--at least for now), but the angular, elongated presentation of stems, leaves, and buds just have this "off" quality to them--but I am likewise a new(er) gardener, so I'm thankful for everyone's comments and input!

    Yeah, what SamuellaZ6a said would be nice.

    Update: More of the same bizarre-looking growth on other, not-nearby roses (will post later for the group). Sent some photos to Mizzou and K-State; a master gardener via the University of Missouri Extension believes it's RRD, and no word from K-State yet (I imagine they're swamped as one of the few labs still open). I still want to send samples to be absolutely certain, but it seems like a grand cull of the majority of shrubs in my garden is nigh.

    And just so I'm prepared: other than disinfecting shears (which I have normally done after every snip by spraying shears with several sprays of 70% pure acohol, but maybe I'll try a bleach solution instead from now on), how does one go about NOT spreading this around the garden? Would anyone have tips on disinfecting gloves? I have 2 pairs that I have sprayed down with the alcohol spray and let dry in the sun, but would love to hear your tips!

    Ann Peck's ebook on Rose Rosette

    The link will answer a lot of your questions. RRD is less of an issue where I am because of a fairly chronic lack of heat. Winter lack of heat usually kills infected multiflora, while summer lack of heat reduces the spread.

    @mad_gallica (z5 Eastern NY) WOW. Thank you for Ann Peck's ebook resource (so comprehensive!); I hadn't come across it in my research. Looks like if I want to continue growing roses in KS, I've got to read everything I can on the disease.
