What is the best product to use on my hybrid, antique, climbing and english roses (19 varieties in my back yard) to get rid of black spots on my rose leaves? All of them have it. Should I use soap & water and if so, what is the mixture? Is Ortho the best way to go? I'm confused by all the products available so I thought I'd ask the experts. Does the black spot have anything to do with the full bloom roses shrivelling up and turning brown every time it rains really hard? They look like they had the life literally sucked out of them overnight. Thanks for your assistance. |
