mildew on new rose bush
Comments (5)Some roses mildew off and on for their first year or so, and then outgrow that weakness -- so I'd say, give it a little time. OTOH, powdery mildew is a common weakness of fragrant red roses. Mildew is probably our most common disease problem, and I detest it. If a rose doesn't outgrow a susceptibility to it, it doesn't stay here. Wind can be very drying. So a rose sitting in a pot in a lot of wind might be drying out. Perhaps a more protected location might be better. Jeri...See MoreBest Treatment for Powdery Mildew?
Comments (18)I got Grandmother's Hat in Aug '07, so 3 years. And I do have 4th of July, actually 4 of them, and it does not mildew, but it does rust once in awhile in the season. I don't have the others on your list. That said, I exaggerated a little when I said everything mildews here. I recently made a list for publication on the rose society site of roses that don't mildew here, and those were the following roses. Hybrid Tea/Grandifloras: Cherry Parfait (red/white) Frivolous Pink (pink/yellow) Lasting Love (red) Honey Dijon (gold) Stephen Rulo (lavender/brown) . . . Floribundas: Julia Child (yellow) Shockwave (brightest yellow) White Licorice (light yellow) Lovestruck (pink speckled) Playboy (orange/yellow) Gebruder Grimm (brightest orange) Kimberlina (pink) Perfume Tiger (yellow/pink stripe) Hot Cocoa (russet) . . . Shrubs: Darlow's Enigma (white fragrant hybrid musk) Dragon's Blood (dark red big shrub) Red Ribbons (red groundcover) My Stars (thornless dark pink) Rural England (reblooming pink rambler) Route 66 (purple) Mme. Plantier (white once blooming alba) . . . Climbers: Berries n Cream (pink/white stripe) Candy Land (pink/yellow stripe) Fourth of July (red/white stripe) Rhapsody in Blue (it's a climber for me -- purple) Blaze of Glory (brightest orange/red) . . . Mini's: Irene Marie (yellow with red picotee) Swedish Doll (orange/red) Sequoia Twist (orange/yellow stripe) Gourmet Popcorn (white polyantha-like shrub) Gingerbread Man (dark yellow) Gizmo (orange single) Hurdy Gurdy (red/white striped mini climber) . . . Everything else gets sprayed fairly consistently all year. Kathy...See MoreWhite powdery stuff on leaves of my rose bush
Comments (2)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...See MorePowdery Mildew & Milk Test on Roses
Comments (21)Is your Gruss an Teplitz grafted? In Pakistan, all Gruss an Teplitz are own root. Actually, here one just needs to put a cutting from Gruss in some kind of soil and water it couple of time and it will sprout. I will post a few pics of Gruss an Teplitz grown in the fields for commercial use. It's a great sight to see millions of them on many acres of land. I would suggest you grow it own root and I think you will have no problem with your GaT. Or may be GaT is not a good performer in cold regions. But it performs very well in Pakistani cold region up to zone 3 (if protected during coldest period). But since all of them are own root, they grow back in summers....See Moredchall_san_antonio
