Rosetta disease

Hi. New to this forum and a only a moderately experienced gardener! We had what I've identified as rosetta disease on our favourite climbing rose.
I will remove it of course,but we have many roses and now wonder if we will lose the lot?Can I replant,how is the disease spreadand are any roses resistant?
I couldn;t find much information online.Any advice much appreciated.

    Hi, welcome to the forum.
    Could you please let us know where do you live? This is British forum (although there are members from other countries too) and rose rosette disease is not present in the UK.
    Could you also post photos?

    We are in Lincolnshire! Oh .Lord ,well I looked and looked online,but it looked exactly as rosette disease is described,a climber suddenly threw up long,thick,soft red coloured shoots from the base and we have another rose now showing similar looking growth,and the flower stems were spindly and broom like....but obviously I'm mistaken if it isn't in the U.K.,so what is this freakish growth,and can it be dealt with. ( once I thought I had identified the problem I cut the rose to the base, but on the other Rose I'll watch for what I saw and send pictures.)

    Most probably it is just new growth. It can sometimes look scary and it is almost always red.
    Rose rosette canes are excessively thorny, thick and deformed. They rarely grow from the base, they usually grow from a different cane and eventually all new growth is affected.
    You could also have weedkiller damage if you see any deformities. Post a photo if you want to be sure.
    But what you describe sounds like a normal basal cane. You want these new shoots, this is how your rose grows and climbs. Something to be celebrated, not dealt with.

    Oh boy,it's been growing for several years with nothing like this red super vigorous growth! Our favourite too! Never mind the rose canes,my face is pretty red too!

    Hi I live in texas at ground zero for the rosettes disease.  I have lost 5 knockout roses to the disease.  I think the reason it is so bad here is that everyone was planting knockout roses.  The rose was very good at everything except rosettes disease.  I hope you never get it in the uk.

    It does seem that the roses i get from the david Austin nursery here are more resistant to the rosettes disease.  I have only seen the rosettes disease in the knockout roses.
  • It is possible that your rose was spending a few years developing a strong root system before it really got going above ground--the better varieties tend to do that. But I'm puzzled by the 'broom-like' flower stems, so it would definitely be a good idea to post a photo.

    I'm not convinced this rose has it but it looks suspicious due to increased thorns
  • If you are concerned that it might not be the normal new growth or weedkiller damage that @edhelka mentions and still suspect that it could be a case of rose rosette virus, the RHS have a link where you can report suspected cases to the UK Plant Health Information Portal. It's on their "Rose problems: frequently asked questions" page.

    As @Cambridgerose12 says, posting a photo might allow people to give you a more definite answer. I am a total newbie to gardening and know literally nothing about roses so can't offer any advice either way, but many others on here are much more experienced and may be able to help. That way, they may be able to help put your mind at rest. The RHS do describe weedkiller damage on roses as "small clusters of pale green or pinkish-red leaves, resembling mini witches’ brooms", so more experienced gardeners might be able to confirm this for you if you can provide a decent photo of the affected plants.

    Hope this helps.

    @jamesholt Named cultivars of roses are grafted onto rootstocks.  If your rose is badly planted - eg insufficient depth - or the graft union is damaged, the roots will produce stems themselves and these will be thornier and often a different colour and leaf form from the cultivar.   If you leave them on they will suck all the vigour and weaken the cultivar so check and see where your rogue stems are coming from before you decide it's disease.
