| I know there are a few of you out there who garden in places where powdery mildew is a big issue. Lots of Teas seem to have a tendency to get it badly. Could you please recommend a few Teas and Tea-Noisettes which seem to be more resistant to it? Large, small, bushy or climbing anything goes. A little bit of PM I don't mind but I have decided to throw any PM magnets out of my garden be them teas, bourbons, HPs, HT's, hybrid musks or whatever. I just can't stand it anymore and I'm not going to spend the rest of my life spraying stuff on roses. Nik |

| Many teas have left my garden due to PM, and many of the remaining teas get a touch of it during "PM" season (now), but are redeemed by looking good the rest of the year . I can recommend three that have never had it here: Etoile de Lyon, Niles Cochet, and Souvenir de Pierre Notting. Of the tea-noisettes, my experience is that they all get some now and then, but it tends to be worse on young plants and transitory and less blemishing on established plants. |

| I don't have much powdery mildew in my climate, but I do have some but don't recall seeing much on my teas. I've not noticed any on Mrs BR Cant. She is an incredible rose in my climate. Duchess de Brabant and Mrs Joseph Schwartz are also pretty free of pm, as is Maman Cochet and all her sports. |

| Powdery Mildew R Us. And I long ago decided that in most cases, things that mildew (or rust) all the time just can't stay. I've found that some clones of Duchesse de Brabant are HORRID mildewers here -- I've tried three. The one I have now, which we collected in an old cemetery, has never mildewed, so she's getting a spot in the ground. NEVER have seen mildew on the Cochets: Niles Cochet, Maman Cochet, and White Maman Cochet. The NABONNAND roses seem to be completely immune to mildew (at least, they are, here). General Gallieni and Rosette Delizy are wonderful here. So, so far, is the Vintage Gardens import Alice Hamilton (another Nabonnand). Mons. Tillier has never mildewed for us. Etoile de Lyon never did. Mrs. B.R. Cant isn't real happy here, but she has no disease problems, at all. Lady Hillingdon is in a miserable shady spot, but no disease. Now, there's Mme. Lombard. She has a reputation as a congenital mildewer -- but THIS spring, she is finally mature, and she has had NO mildew. She's covered with sparkling, perfect foliage (see below) and a mass of buds. My fingers are crossed. Maybe it is that she likes what climate change is doing to this environment. Jeri |

| Thanks all about the comments and recommendations, noted. DdB I have as this year's grafted bareroot from Peter Beales' in the UK. I have sprayed it 3 times already out of fear it might die on me due to PM... Which goes to show...If she doesn't sort herself out by next year she's out. She's 10'' tall btw but full of blooms and buds. Which goes to show... Keep it coming folks, please. Nik |

| Nik - I agree with everything Jeri said about teas which do not mildew here. I would add that I have Safrano, which blooms from Jan through Oct with no signs of any disease. Also 3 plants of the tea noisette MAC (can't really call them "bushes", as they are 20-30 feet high) which are clean w/o spraying . How old are your teas? Evidently some teas "grow out of" getting PM when they mature. If they still have it after about 3 years of age, I would get rid of them too. Jackie |

| Hi Jackie, all my teas are young. I'm a very patient gardener. Which one's MAC? I'm no good with acronyms. Nik |
|
| For me, Rosette Delizy, Mlle. de Sombreuil (a young plant), Le Vesuve and Mrs. B.R. Cant are the good guys. My worst ever was Alexander Hill Gray (naturally it had the most gorgeous flowers). Souvenir d'un Ami has no mildew in spite of the heavily mildewed Miss Atwood hugging him on one side and the equally mildewed Mrs. Dudley Cross on the other. Le Vesuve is leaning into the mildewed Mrs. Dudley Cross on the other end and is still clean. William R. Smith is also virtually without mildew. Ingrid |

| Just remembered that Clementina Carbonieri had perfect, beautiful foliage, too, but is no longer here due to the flowers having virtually no heat resistance -- not a good thing in Livermore! |
