Which ever RMV it is it's probably not an automatic death sentence. I have roses with RMV that are 20 or 30 years old and still going strong. And I have mighty cold winters most years. The symptoms do show up most often when the plant is stressed for some other reason like heat or drought. Otherwise you wouldn't be able to tell which ones they are. They grow and bloom with the best of them.


Yes, it is rose stem girdler. There will be a swollen area at the bottom of the dead part with shallow spiral tunnels under the bark. Just cut below that and bag the swollen section. If you do this whenever a cane dies, you will break the reproductive cycle.
This pest prefers rugosas and it occurs from here into the far north of rose territory.


Higgs, I personally POP the little devils with my fingers. They do pop rather satisfactorily! If you don't feel up to that, you could hose them off with a strong blast of water, aimed upward, from under the foliage.
But popping is more certain, and satisfies a bit of savagery in human nature.

Lynn, my Don Juan is about 8-9 yrs old, southeast corner of house (best spot for our climate) and receives irrigation from both the spray-pattern emitters positioned on it and a deep-flood from the hose every couple weeks during the summer. Today the high is 116F and it'll be over 110F for the rest of the week. Possibly I just have a bad plant but there hasn't been a 3-inch bloom on any of my roses since July 1... about the time it hit 115F several days straight. That's pretty common around here especially after the monsoon winds come rolling through on top of the heat.

moroseaz,
Your current temperatures are similar to our July and beginning of August, with the exception of a 120+ day here and there ( July). Having those regular 100 teen days in August too, separates Las Vegas from AZ. We hit 106, I believe, today, and last weather check we were in the 101-103 range for the next few days, so about 10 degrees or so more where you are give or take; which is significant. Our temperature decline, while it is still hot, begins in mid to late August.
My Don Juan is watered daily via a drip line irrigation that sends water down around the root zone. It also is well mulched. My first flush was from late March or early April all the way through mid June. The current bloom is the first 3" bloom I have seen during the summer. In August, unlike July, the plants receive a reprieve as the lows dip down into the high seventies or so for hours, whereas in July, it dips down into the mid to high 90's for a couple of hours or so.
Your Don Juan has definitely been there long enough to show you how it is going to perform given the same input.
Good luck.
Lynn

The ARS trying to sell HTs of any kind as a "gateway" rose to bring in new people who want to grow roses is so antiquated it's silly. Please tell me that the goal of this whole thing wasn't to increase general rose sales.
Believing my only options were HTs I didn't grow roses in my perennial gardens for 20 years. It wasn't until OGRs became something less fuzzy in my mind and I realized I didn't have to purchase my plants locally (since no one sells OGRs here!) that I dipped my toe in the rose world. A study that (1) promotes HTs and (2) claims something you spray is "easy." Would have done nothing to capture me and that much more to push me away from roses in general.
Having it taken so long for me to finally find Tea roses it makes me sad to see them so maligned by associating them like this with HTs--intentionally. I really get why someone like Jeri would be unhappy about this. It's like her life's work of educating us about Tea roses has been hijacked. Just as she seems to be making some traction they come in a try to steal the goodwill she and others have built for Tea roses by erronously glomming on to the "Tea" name.

Consumers, in general, have often confused HTs and Teas because they just don't understand the difference. We see it here on the forums all the time. "My Tea rose.." and it regularly is an HT. The ARS' mission statement says they exist to EDUCATE. I'm glad others see the fallacy of this "education", too. Kim

Hello Henry:
Nothing new- we get called to a lot of "problem situations" that turn out to be RRD. We saw our first RRD in garden situations some years ago- about the same time Terry did - might have been some before that misdiagnosed as weed killer damage. I've got to assume it had already showed up on wild multifloras. I used to tell people to bring their infected roses to their county extension - I don't even bother with that any more. They've probably seen enough of them.
Wild multiflora roses have become significantly reduced in this area in the past few years - even the ones that were planted as highway barriers are significantly reduced. That's got to be from RRD. I assume the ones that are left are somewhat resistant to the virus. Since this virus requires a vector, that might be succumbing to natural predators as well.
Here is a link that might be useful: Featured Creatures: eriophyid mite vector of Rose Rosette Disease (RRD)

Hybrid teas are the ones that got me hooked, so they will always be special to me. I think they can be quite beautiful planted en masse and the individual blooms are lovely, many have wonderful fragrances. I love all roses though and want to give them all a chance. Maybe not Knock Outs, but even they serve a purpose.

Why can't they understand? I feel your frustration. My dad made a mess of the garden too when I was just starting out. After a while he stopped. I have had plumbing crews and other service people smash down plants far outside of the work area, even those roped off. I can never understand it. Sometimes its like you have to stand right there watching and waiting to be ready to make a rescue. I do whatever I can myself and try to hire people that will listen if I can't do it myself. It's that " they're only plants " way of thinking and it drives me crazy.
Keep them watered and clean up any raggedy cuts. I would probably go in and cut out any dead growth and clean up/ shape the plants as long as they are getting a trim now. go together to buy some mulch to help them along since they don't have the leaves shading the roots now and the heat will come on. That makes a big difference in helping them bounce back. As soon as the heat passes, you can feed and I bet you'll have some great roses around Thanksgiving. Let us know how it goes.

Thank you all for your responses. Hopefully he will get the hedges cleared out soon as it is a mess right now. But I will keep in mind to water and fertilize after the heatwave is over. I'm going to cross my fingers that they grow back. I think I am more annoyed that he doesn't care about landscaping and can't appreciate it enough to maintain things. He just wants to get rid of all the trees, hedges that he can get his hands on. I need to keep an eye on him when he walks around with the cutters.

Hi Tigers,
I have Chrysler Imp and Veteran's Honor. Plus I'm an aussie living in the USA but I know Melbourne fairly well! I love both these roses but 2 things: you will definitely have to spray regularly and I'd place them where they get sun from sunrise to noon or so. CI has the most fantastic fragrance, beautiful rose form and is quite a nice shaped bush to boot. Veteran's Honor is simply the most amazing vivid shade of red I've ever seen. It's incredible. Unfortunately, little to no scent. Seems like a nice plant too and pumps out the flowers. Have you been up to the rose gardens at Weribee Park? It's been quite a few years since I was there but they used to be great and they might have specimens for you to check out.

Thanks guys for all your help great info.Yes I have been to the rose garden in werribee wonderfull place and great roses there.I'm just looking forward to see how all 3 go to be honest after reading and speaking to people about them.I must say all 3 roses are pretty rare to come across here.


I envy you guys who share your rose obsession with your S.O. But then I remember he shares my horse obsession, so it's all good. It's really kind of funny, because he doesn't understand spending hundreds on roses, but wouldn't blink if I suggested spending thousands on another horse.

Thankfully I do not have the room for spending hundreds on roses, well after I add in the fact I just started my 'container garden' this year. So now it'll just be maintaining haha.
My SO is half and half with supporting. He knows how happy these roses make me, though with the state of the porch, he kinda grumbles when I suggest walking through the garden center hehe. He's actually even helped me on occasion when I ask nicely for a strong man :)
And update for ya'll, those 3 roses came in today and not one comment was made by him, AND yesterday when we wandered through my Lowes, I found the stevia plant I've been looking for all season and he suggested I buy it now! Yippee!




No problem, My rose outgrew me which made me happy at first, then when getting the roses got to be a serious pain I just cut it all hahaha...
Just cut some branches 6 days ago.
I grow Caramel FT as a small climber, the main canes arch over, and the blooms come off of laterals. I cut a lot of it off after the first flush (early July). It is now in full bloom again, the only one (other than Blushing KO) in the garden that looks good.
