Anyone here know anything about rose bushes? I live on a very dusty street my roses are close to the street, the leaves get covered in dust everyday, I have yet too spray the bushes to clean them because, all the warnings about roses being sensitive to fungus caused by moisture and I already am fighting that. Is it possible that besides fungus that the dust could be also causing health problems for my roses like stunting growth and recovery? I hope someone has the answer because I realllllllllly don’t want to wade through forums about plants.
We always gave our roses a good once over with a hose about once a day and never had any fungus problems. We live in Colorado so not as much dust to deal with, but just a spraying shouldn’t do that much to them. Not enough to just keep the dust off.
Thanks Sky, here in Mississsipi the humidty causes fungus and that the coating of dust will either increase the fungus or protect it maybe. I have to admit I really want to go along with you on this just by gut instinct alone. If anyone else has any knowledge either agreeing with Sky or contrary it would be apreciated, I generally am pretty good at killing plants. I really don’t want to kill my roses if I can help it. Believe it or not I have actually killed cacti. by neglect and overwatering
talk to your local plant distributor or whoever sold you the roses…

Ah yes… The black thumb syndrome. I know it well. Rinse 'em off and watch for fungus or powdery mildew. You may have to keep a fungicide handy and give them a little help now and then. Here in Slickrock we have all of that plus aphids. Not to piss off the organic people, but I’m a strong believer in better living through chemistry… 
Uh the roses came with the house and I have tried a couple of the local nurseries but all I get is about the same answer. “We have a book we can sell you that might answer your question” also I really only leave this place about once maybe twice a month and go to town.
Asking my hubby to pick it up would take a month or two for him to get around to remembering that I was reallly serious about him getting it for me. 
I agree with the chemical living to some degree but, our cats eat the leaves at least the lower leaves. LOL I have one small naked rose bush which seems to be the feline favorite, it also produces the most sugary sap too. So I have to be careful and organic for their sakes. Wood ash and ivory soap help deter some fungus growth. I would use tobacco but, nicotine is highly toxic to cats too.
so so far the vote is give the roses a good rinsing , I think just before daybreak would work best so that they can dry off quicker and not burn.
