Hi I'm new to the "Garden" and have 36 roses in my collection of perennials. I've had roses for nearly 30 years now but am having a serious problem w/ my roses that I've never had before. The leaves at the top of about 1/3rd of them are a rust color even orange on the worst affected. Along w/ the regular schedule of Shult'z rose food I've used for years I have added iron/sulfur, magnesium, phosphorous and potash, I believe one of those is helping as some improve for awhile and then they start it again. I can't find anything that describes the rusty/orange color in the books I have. Does anyone have any ideas???????
I'd send a pic but really haven't had time yet to get one. We've had so much rain ever since early spring and I'm thinking some important nutrient has leached out of the soil
This is a crazy busy summer as I am also establishing and caring for new 10 new beds as the volunteer gardener at our local domestic abuse center. I'm hoping to make full use of Dave's Garden and all of the collective knowledge here.
Thanks for any help you can give
