| I am a snoop here on this forum. I hang out on the daylily forum but I have a Rose that is growing weird. I bought this rose in 1973 and it has done so well all these years. It has growth that has a million thorns and the foliage is rather dark and kinda reddish. It has a bloom that comes on and is nothing like the original. Any comments would be appreciated. Thanks...Ellie

| Well, two possibilities. One is that a rootstock for your original rose has established dominance....explaining the change in growth habit and flower. Another is that you have a Rose Rosette Disease case. I'd recommend you have a local Extension agent come out to identify the problem for you. If I had my bet from your picture, I'd go with rootstock...most of the RRD cases have many more and smaller thorns and the foliage is all purple. |

| A third possibility is it got hit by a herbicide like Round up. Even a little spray drift will cause similar symptoms. |

| That growth looks like healthy Dr. Huey to me (rootstock). Is the "nothing like the original bloom" red? Check to see where that cane is coming from. Is it coming out of another cane, or is it coming from way down in the dirt near the base of the rose? If it is coming out of another cane, it might be a disease or herbicide damage as described above. However, if it is coming straight out of the dirt, or way down at the base of the bush, then it is probably rootstock. What you need to do is dig down until you can see where it is growing out of the main base of the rose. Do not cut it off at the dirt level - it will just grow back stronger. You may need to dig down several inches below the surface of the dirt until you get to where it is sprouting out of the main stem of the rose. Then cut it off flush with the main stem, put all of the dirt back in the hole you dug, and hope that it does not re-emerge. If you let it grow, it will eventually kill the main rose, and you will be left with a rose bush that is 100% rootstock, which will probably only bloom once a year. Jackie |

| More and better pictures would help. We need clear unobstructed close-ups of stem with unusual thorns, of any unusual branching, of unusual leaf laid flat alongside a normal leaf if there are any of the latter. On the central stem with russet foliage, I think I might be seeing many long awl-shaped thorns that are pale-colored. If that is what Is really there, it's weird enough to suggest the dreaded rose rosette disease. The oversized crumpled purple leaf in upper left is also suspicious. Do look up the Dr. Huey rose and check out the flower. |

| The original bloom on this rose is pink. The new bloom is pink but much smaller and darker. It couldn't be caused from round-up because I haven't used any this year! Or last year for that matter. The growth is in several places coming from the limbs, well above the ground. I may add that when I touch it to break it off, it's very tender and requires no clippers. I have another rooting from this so I may just cut it down to a couple of feet and hope for the best! Thank you all for your help and input! Ellie |

| Let me encourage you again to post informative pictures that illustrate clearly any differences between the strange new growth and normal growth from further down. If your rose has rosette disease, it is incurable and contagious. The plant must be removed at once. The dark pink flower means we can pretty much rule out the hypothesis of rootstock suckers, and you haven't used herbicides. |

| Michaelg, here are some more photo's. This bush is about 4 ft wide and 5 feet tall so it's rather hard to get in there! This is some of the bad! Notice the difference in the leaves. The ones surrounding the bad stuff are healthy.
this has a bloom trying to get through..
This is part of the "growth" coming from a seemingly healthy limb.
healthy limb!
Another pic of the bad stuff!
Healthy .

| Unfortunately it appears your plant has RRD (rose rosette disease) the excessive thorniness and "witches broom" growth habit of the foliage are diagnostic. The disease is spread by mites which can and will infect other roses. Sorry to say but the best course of action is to remove and dispose of it. |
|
| It does look like rosette disease. Don't delay removing the plant, but treat this as an emergency. To prevent escape of infected mites, it is good (though optional) procedure to spray the foliage with hairspray or Wilt Pruf. Cut and bag the canes, and burn or send to the landfill. Immediately after cutting, brush the stumps with full-strength Roundup and wait a week. This is to kill the roots, because any suckers from roots will be infected. Then dig the plant. If this seems too complicated, just dig, getting as much of the roots as you can, and bagging the foliated parts. |

| t-bred & michaelg, I have cut the rose bush to the ground and bagged it. I will spray it with round-up tomorrow. My other roses are on the otherside of the house so hopefully, it won't affect those. Thank you all for your help because I didn't know what it was or what to do. Come visit us on the daylily forum. lots of nice folks there too!! Ellie |

| Mizellie, sorry again that you lost a plant that you have had for so long, you did the right thing though. |
