| These roses were put in last fall, so this is the first time I've seen this issue. The new growth and buds look stunted and flowers are incomplete. The buds are very small and crinkled. I dissected the buds and didn't find insects or disease. I used Bayer 3-in-1 granules about
1.5 months ago, and about 1.5 weeks ago, I applied miracle grow foliar application. Some of the canes/buds appear normal within the same plant. The get irrigation 3 times weekly. We've had more rain last week than the last 2 months. Please Advise. Please see pics, I have also added what the plants looked like 1 month ago. |

| oh wow that bloom was beautiful too.. |
|
| Maybe just a whiff of herbicide--roses are extremely sensitive to them. |
|
| Chilli thrips have been reported from your part of the world; there are some good sites with lots of chilli thrips affected roses pictures. |
|
| Have you been spraying around there for weeds? With something like Round-UP? That stuff can produce some rather weird growth and blooms sometimes. If that is what it is, I think all you can do is wait--in a couple months it will hopefully start growing normal again. Kate |

| I recently had to put down a fungicide on the turf, but that should not have bothered. I am going to put out my lense tomorrow and take a closer look. I know that Chili Thrips have been a problem but I have never seen them to know what they look like. |

| Ok....duh. I got out there with my lense and couldn't find anything. Then I looked over and realized I, in fact, recently used round up about 20 feet away. Could it have drifted that far? I don't recall it being breezy the day I used the roundup, but the timing that I started seeing the problem coincides with when I used the herbicide. |

| The drift and "bounce" from R-Up is much greater than you think. I have a large piece of cardboard that I use to block the drift when I'm spraying weed killer. I also use different sized bottomless cardboard boxes in closely planted areas. I put the box around whatever it is I want dead and spray down into the box which blocks any drift or bounce. |

| Round Up can drift on the air amazing distances. Even a tiny amount will badly affect roses - I don't use it. Once my next door neighbors gardeners used it in his back patio, and it KILLED a rose in our yard. Really nasty stuff. I would wash them off well with the hose, water them well, and just wait. Do not feed them for a while, until they start putting out normal growth again - they will be OK. |

| thanks for all the input. I would have never thought about the herbicide! |

| I lived in Port St. Lucie for 11 yrs. Grew about 120 roses. From about 2003 or so I fought a constant battle with Chili Thrips. You might not see them, but that damage looks just like their damage. Retired and moved to N.GA in late 2008. To cold in the winter for Chili Thrips up here. I don't miss them ONE BIT!!! |

| I would agree the stunted growth looks like chili thrip damage,but there is no curling of leaves or yellow/brown leaves either. |

| I just came across an article on Rose Rosette Disease. My stunted buds and new growth look a lot like this. |
Here is a link that might be useful: RRD
|
| The reason no one has suggested Rose Rosette disease is that you live in Florida. If you have no discoloration of the kind that chilli thrips produce, it is probably herbicide. There are some other uncommon viruses, rose leaf curl and rose spring dwarf. It is probably too hot for spring dwarf. |
|
| I wonder where that henry guy is that always talks about round up... He/she would prolly know... When you need his input he's not here but when you don't he is here... sorry had to say that.. |

| Are roses in Florida not effected by RRD?? |
|
| Florida roses share RRD susceptibility with all other roses; but (and this is where you have been lucky, so far) you have water on three sides and you seldom have winds from the north in May through September (this means you don't get cold fronts then either.) The vector mites for RRD are wingless and windborne. For them to carry RRD to Florida from areas to your north would require right wind condition + being a time of year, up north, when mite populations have built up. Florida isn't totally free of RRD. Two Hybrid Musks near Tallahassee were diagnosed with RRD over five years ago. Multiflora isn't common in the southern halves of the Gulf Coast states. That's a good thing for youall. A bad thing for youall is that R. laevigata can catch RRD. I know because mine has it, and I have a report of it just south of Charleston S.C. One thing on the pictures that is really interesting: the blooms on the affected roses. Your use of the word "Stunted" is a very good description of both leaves and petals. The blooms' petals are truly stunted but what caught my attention was the deep color of the petals. Of the many plants I've seen with RRD, I've never seen a situation when the petals got changes in the colors to make a deeper petal color. I've seen a lot of pink roses with RRD and pink Knock Outs with RRD....the colors have tended to become lighter, or splotchy. Do you have a scanner with your computer? Most scanners can be used as a microscope to see if you've a mite problem that is below the limit of what we see with the 'naked eye'. Ann |

| I live in California, hear we don't have RRD here. But if you looked at a couple of roses at my bosses house, you might think we did. BUT I know differently-cause I saw the bosses gardeners busy with roundup killing weeds in the driveway. |
|
| LOL Jessica, I was thinking EXACTLY the same thing.... |
|
| kippy I would knock on wood... :) buford: :-D |
