Hi all....I panicked and pulled out that rose,and a multiflora wild rose that was growing near by..the other roses seem to be ok thank god.one thing is for sure..no more knock outs for me! Never liked them much anyway.the virus is out there though.seen a few wild roses with them.on many landscaping projects in front of malls etc,there are rows and rows of knock outs half dead.ill upload more pics tomorow
Knockout's are not any more prone to catching RRD than other roses. There is just higher percentage of Knockouts planted because of their popularity. So it looks like more Knockouts come down with RRD than other roses.
If you go to Blog talk radio and enter rosechat they have episodes on the subject...plus it's a great show if you'r a rose lover :D

That's interesting Seil (though of course disappointing). I see that occur off and on in my roses in the ground as well, when the canes leaf out just fine then shrivel never more to be seen. I think the cane stores up just enough energy to put out some leaves but without the roots it can't sustain the growth.
I had a dramatic proof of that last year when I received a rose in a band pot that had literally no roots (the company of course replaced it). I went ahead and stuck it in a band pot to see what would happen and I was pleased to see it put out leaves, but after it shriveled and died, I pulled it out and there were still literally no roots. I guess that's why we in colder zones are most concerned about root/graft survival, since there's nothing to save the rose if that goes.
Sympathies on these two plants, vampygirl - if it's any consolation, Marilyn Monroe gave up the ghost on me in the ground in my zone 6 pocket without a fight, so I expect she's on the tender end of HTs. Chicago Peace has more fight in it if you want to replace it.

Reds- I would suggest you look at Don Juan. I just had to move a 5 year old one when we moved and it was a good 14 ft tall and covered with big red blooms. I have a small RU that I am currently loving.
Yellow-You are 6b so not sure a Tea would work for you, but Climbing Lady Hillingdon is a gorgeous yellow for me. Sky's the Limit is also supposed to be great and if you want to try an Austin I have seen some impressive Lady Hamilton roses grown as climbers.
It should be a very healthy, vigorous bush for you. Expect it to be about five feet tall by four feet wide. When it develops multiple canes, you won't need to tie it to anything. All you really need to do is feed it a good balanced rose food according to the instructions on the fertilizer package and water, water, water.
If you post a photo of the open bloom on the antique roses forum, someone will tell you the name of the bush.
Yellowish new foliage with green veins is iron deficiency. This is usually caused by high (alkaline) pH. Check the pH and get some sulfur at the garden store. This will very slowly acidify the soil. You could also apply an iron product such as iron sulfate granules. Don't overdo either of these treatments and be patient. I would not remove the young yellowish leaves. They can be greened up.
The plant can be made more bushy by pruning, but since it has had a hard time, I would leave it until early next spring, then cut back part way.
A Burbon that fits the bill is Louise Odier. Both of my plants are 4-year old, and each has a very small fall flush (the emphasis is on the word "small") that can last into November.
Archduke Charles is another that might work. It is a China and might be only borderline hardy here, but I did recall seeing a reasonably-sized plant at the P. Rockefeller Rose Garden in the Bronx. Haven't been there this year so I don't know if it has made through this past winter alive. . Another rose that may qualify is Baronne Prevost, a Hybrid Perpetual, which I think you can find both at the Rockefeller Garden an the Cranford Rose Garden. I don't grow either and cannot tell you how big a fall flush you can expect from each.
"So lovely, thanks for sharing. In my next life, I am going to live in California. (smile)"
Oh, donaroe. You cannot imagine how often I think of you all who must make such a valiant effort to have the roses we love. It staggers and shames my lazy bones. My respect and admiration swells whenever I read your posts about the work that goes into your roses. My friend in Ohio brings her geraniums inside each fall, and a few roses, as well. I am truly made humble.
All of you made my day with your kind replies.....even more so, 'cause
my garden is puny by comparison to many of yours.
Such a really nice group you all are on here!

P.s. One more for Leslie: Just Joey
The Connecticut Rose Society's rose show is this Sunday, 6/15, at Elizabeth Park in West Hartford. It is a wonderful place to see many varieties, including the ramblers. It looks like ~1 hour from Fairfield.

Sorry to hear about the violence :( Anyone cruel enough to hurt a defenseless animal is a menace to society and needs to be caught and punished.
This might not suit your needs, but I thought I'd mention it. My neighbor who has had trouble with neighborhood dogs going after his chickens installed cameras that required no wiring. He said they are available anyplace you would find hunting equipment. They are motion sensitive, battery operated, and just have an internal memory card. He has them mounted on tree trunks.
Rat dogs
We tested one of the game cameras. They do work great but want to be north facing and the street is north facing. So we got every car that drove by. Lol.
I am going to put up signs that say under 24hr security camera etc. You would be amazed at how much just posting signs change what people do.
Great! Thank you, everyone. That's all good to know, and a big relief. OOPs on the date - I didn't realize the year was off. That'll get fixed like now.
*All* my roses consist of 4. I'm nowhere near where any of you are, just starting with not a lot of room in the sun. But yes, they get watched plenty as will this one. I'm really curious as to what it might turn out to be. If multiflora, as long as it's healthy and I can find a place for it, COOL!

Thanks for the help problem solving guys! I did have to chuckle a bit at your California gauge of how tall roses should be by this time of year, Kim, given the assumption of different height and air patterns with the columbine. Sadly, after this brutal winter nothing but the climbers are blooming at anything above knee height after being pruned to the ground, which puts them at exactly the same height (and presumably same air patterns) as the columbine pods.
I tend to like the theory of the plant-specific type of aphids going on here, particularly since it's so all or none on the plants. These are definitely the actively crawling (green colored) aphids, not just the honeydew residue, though I'm sure stickiness has something to do with them staying put for now.
WHICH of course raises another question in my ongoing puzzled brain - are there aphid-species-specific predators then? Are the peach aphids tastier than these "columbine aphids"? If not, then what's up with my usual ladybugs and other good guys? The columbine infestation is heavier than I usually notice for the first flush of roses, and this level of aphid swarm would definitely get my attention if it was on my roses. Presumably the predator level has to rise to the level of the food to be consumed, but it's definitely a greater imbalance this year than I've ever seen. As I've mentioned, I've seen fewer ladybugs this spring than usual, though plenty of other assorted bugs, and I was wondering if the harsh winter cut the usual spring population back. Usually they're crawling out of the mulch as soon as I pull it back from the roses, and invading the house all spring, but this year I saw none in the mulch and only one in the house. I'm sure they have some dormant eggs that will hatch eventually, but the inquiring side of my brain that is no longer consumed with rose planting is pondering the other half of this equation.
It's interesting to know that the peach aphid is the culprit for roses, Michael. OK, one more curious question on that account - I recently planted a peach tree in my yard, which is a good 4 years from blooming and even further from setting fruit. Still, once it does bloom, would you guess that having the roses to attract the peach aphid hurts the peach prospects or helps because it also attracts the predators? Being mostly organic (aka lazy), I'm unlikely to do anything about it unless it gets particularly bad, just curious.

Predators usually lag behind pests. We'll have a particularly wet winter and the following spring the pests are legion. They respond seemingly immediately to the increase in resources (food). The predators lag behind a season or two, but eventually catch up. I'd bet your lady bugs were either harder hit by the conditions or are slower to respond to the improving conditions, as if to naturally make sure there is ample food supply before they do their things. Of course not "consciously" but by development. Kim
Mr. Kim Rupert: Roses are evergreen with little to no blackspot issues (or other diseases). Prolific blooms throughout the season.
Kordes: Generally very healthy in the 8a (Pacific Northwest) climate.
Francois Lacharme, for his magnificent Bourbon/Noisettes which, alas, I can't grow here.
I can now add Jacobus, now that 'Morning Stars', 'Autumn Bouquet' and 'Dream Girl' are growing back; I thought I had lost them.
