What do you folks think?
Do they need to be taken completely out?
I have cut 2 of the bushes to all but 6" from the ground. I'll see what they look like when they start leafing out.

The ones in front of the house (no pics) seem to be ok.
Thanks

They do look bad don't they? So sorry, but I think they have Rose Rosette Disease. Everything I've read on the disease says you must get rid of the rose bush. Even the roots. Otherwise it will spread. good luck.

Yeah, sadly it looks like it to me too. Mine were t***** but they never had that many thorns. It's such a shame because they are so hearty otherwise.

They look like such a beautiful variety Boooo Hoo for Birdie! You might even need to refresh
the soil in that area before planting anything else there? No rose expert but they make me want to itch! LOL What causes that?

I'm going to be the odd ball out. I don't think they have it.
Mine looked much like that and I just cut them back to 12-18" this spring and they are fine now & full of blooms.

Here's a link to what is typical on KO roses...

If you want to find out for sure, cut off a good sized piece, put it in a zip bag & take it to your local county extension office. If they can't answer, they can send it to the university for testing.
And keep in mind, I'm certainly NOT a rose expert, I'm just going by my own experience with my knockouts.

I would try what gakaren said and I am no expert either. At the moment I have no roses. I was going to try knockout roses but after this post I need to think about it. I thought they were so resistant of disease. I know resistant does not mean they don't get disease. I just never heard anyone complain about diseases.

Ok, I looked up some more stuff on the disease...
Here is a list of all the things that can show it and you should have several of them in any combination if your roses have it....

quote:
Symptoms: Disease symptoms vary with rose cultivar, but combinations of all or some of the most distinct symptoms are used for diagnosis.


· Stem bunching or clustering, witch’s broom
· Elongated and/or thickened canes

· Bright red leaves and stems

· Excessive thorniness, small red or brown thorns

· Distorted or aborted flowers

· Under-developed or narrow leaves and/ or distorted canes

· Dead or dying canes, yellow or brown foliage, dwarfing or stunting


And here is another link with a picture of KO roses with the disease....

The canes look like those of the Rosa Rugosa that grows wild in my yard and gets cut down often as a "weed". Was this KO Rose grafted? If so the root stock has taken over and you no longer have what you thought you had.

I was also thinking what Kimmsr said but don't know enough about roses to confirm it. Guess you need to make up your own mind as to what to do. Frankly the oldtime roses from 60 years ago are a favorite of mine. My grandmother had some in her yard and I remember they looked heavenly. The only problem I remember was they only bloomed once and not for very long.
