Tired of dealing with blackspot--what mini is more resistant???
I have struggled for 3 years with my grocery store rescue mini roses. They have beautiful flowers in my little raised bed outdoors, but sure as shooting, they always come down with dreadful blackspot which eventually knocks off all the leaves. Yeah, I water them from below. Yeah, I have tried various sprays. Yeah, I picked off all the affected leaves and threw them away far from the roses. Nothing has helped.
So--what multi-hued varieties of mini rose could I order online which are more blackspot resistant??
