| we purchased a house 3 years ago with over 100 rose bushes. I have read some about their care and have some beautiful, healthy roses. A few of the bushes have an ugly gold leaf with big black spots. I have sprayed and I try to cut these leaves off each time I deadhead (once a week). It is better, and only a few of the bushes have this, but I want to get rid of it. What is it called and what do I do to get rid of it all? then I have some very light pink roses that will have about 8-10 buds on one stem but the edges curl and turn brown and they don't last very long once they are cut. I believe they are some type of peace rose. Is there anything I can do to prevent this? One other bush is climbing and is also some type of peace rose-a salmon pink color that has tons of wonderful smelling roses. It's leaves often have a white filmy substance on them. At first I thought it was just diry, but this seems to be some sort of disease. What is it? and what do I do for it? It seems better since I first sprayed in May, but I would like to know what it is. Thank you for your response |
| Roses require a lot of care but you'll be rewarded by your efforts. What you describe are the symptoms of the most common rose diseases; black spot and powdery mildew. Each has its own set of control options. Rather than attempt to cover all of the options in this forum, I'm going to provide a website address sponsored by the American Rose Society. Everything you need to know about growing roses and controlling diseases is explained in detail. I'm sure this website will provide lots of help in getting your fabulous rose collection back into shape: http://www.ars.org/About_roses... When you get to this page, click on Powdery Mildew, and the Black Spot and when you've finished reading the basics, you can surf the site for info on feeding, pruning and watering your roses. Best wishes with your roses! |
