There are several good recipes for powdery mildew here and on the web. There's a good one that I have used on Garden Web that you can find just by searching which is baking soda, dish soap and water. I bought a couple of roses from Rite Aid around Mother's Day. They both had powdery mildew so when I got them home I star washing them with water, used the baking soda mixture referenced above, transplanted them into bigger pots with good sun and air circulation and the problem went away in short order. Then again some roses are PM magnets. I might be chucking one of my new ones this year soon for that reason. But I'm sure someone will chime in with the exact recipe you need to try and fight it. Hope this helps. Kate

I am having the same problem or two of my older mini's. I know it is important to keep the leaves dry and have them in the sun, but I still have the problem. I have tried an organic spray for mildew but it did not help. A couple years ago I just drastically pruned one with this problem and it grew out ok. If you find an answer let me know. It is frustrating! Linda

It's been years since I've dealt with this, I had one climber that got this every year. There wasn't anything back then, in the 80's that would stop it. I would have to say if it's shriveled that you'd need to prune it, you have to cut off the affected area, powdery mildew spreads on dry foliage. Why don't you take this and post it on the main rose forum and see if someone will offer up a solution since you're not getting any answers here. I'd also go and look at the Lowe's or someplace at the spray's and see if there is anything topical that you can use. Sorry I'm not much help. There may be something you can use to keep it from spreading, one method suggested is to wash off the spores each day late in the afternoon or spraying it with Neem Oil. I'm sorry, I lost alot of plants in the freeze too. Good Luck to you. Leslie

Hi B2, Yes! Roses do very definitely get mildew! I'm linking a thread where I expounded upon my own personal theory on how to minimize the problem, and there will probably be others along with info on what works best for them. When I was in the green industry I used some of the different commercial mildew suppressants, with little improvement, and here at home I had tried the "home remedy" kinds of things like baking soda and milk, but the only thing I've found to work for me is the "watering theory" I talk about in the linked thread. The swap WAS fun! Hope you can make it to the Fall Swap! (Hope I can make it too! I'm taking my vacation a couple weeks earlier than normal this year, and I happened to think, about a week ago, that that might keep me out of the mix this fall! Will just have to wait till then and see what date gets picked!) Good luck with your roses, Skybird Here is a link that might be useful: RMG: Roses
