Blackspot on Knockout Roses

Posted by Vetlor Foothills of NC (My Page) on

We have 3 knock-out roses in the middle of a boxwood hedge. (see photo) My wife has fought blackspot fungus for years and is ready to give up and pull them out. Someone suggested that the reason this supposed resistant plant is so plagued is because of the surrounding hedge. (The Japanese Beetles also drive us crazy but they have been worse on the okra this year and really really loved the edamame plants last year.) My request is for suggestions for another colorful plant to place in the middle of this boxwood ellipse. We love the multiple colorful blooms of the knock-out roses but they are far from being carefree.
