White stuff on leaves
I have another question. This year my roses also had a lot of white
stuff on the leaves. I think that this is mildew or mold. What is the most organic way to get rid of it? Any advice would be appreciated. |

oups.com... I have another question. This year my roses also had a lot of white stuff on the leaves. I think that this is mildew or mold. What is the most organic way to get rid of it? Any advice would be appreciated. I'm fortunate to live in an area where my roses are bothered by not much of anything, except some blackspot, so any information I give isn't based on my experiences. A good source of information on rose diseases is Baldo's site: http://members.tripod.com/buggyrose/ By your description, you might have powdery mildew. I do get it occasionally on one rose and one or two of my crape myrtles. I wish I could recall what I did, but I can't. Here's one site I found that lists cultural, chemical and organic methods of control: http://ianrpubs.unl.edu/plantdisease/g1321.htm Here's another that recommends milk (first I ever heard of that!): http://www.gardenerspath.com/article...erymildew.html I might try that myself. Rosarians who live in susceptible areas tend to spray on a regular basis for a variety of diseases that affect their roses. You might check a local nursery or botanical garden to see if such practices are recommended for your area. Gail near San Antonio TX Zone 8 |
