I just hate the look of blackspot on roses. To me the rose as a green leafed shrub has to look good in the landscape. Not just look good in bloom. Of course they look fabulous in bloom, they just need to look decent out of bloom also. It needs to fit into the garden in whole. I have so many things here, hardly just roses.
I know there are many people who say live with some blackspot and choose resistant varieties. Even a resistant variety can't stay clean in our humid weather and any blackspot is more than I want to tolerate.
I spay with the liquid fertilizer here the same every two weeks as I do with the fungicide. I just wait until there is a bit of spring growth as I have always just put on the bagged Rose Tone first thing in the spring after I see new growth coming.
