Just looking at your rose photos gives me the feeling that you have been, and will continue to be successful growing roses.
A long time ago I got sick after using some chemicals on plants and since then I decided if a plant needed constant spraying then maybe I should select more disease resistant plants. It's good to know there's a book available to help those of us who prefer not to spray.
Sounds like a book I will have to read!
Thanks, Margie.
