    Black spots are a fungus. Apply a systemic three in one control for fungus,insects and fertilizer by Bayer

    I second the recommendation for Bayer 3-in-1 and would add that the granulated is better than the liquid concentrate, due to its time release formula.

    contact the local rose society...there is one in every state....or state agriculture department for ideas proven in your area.....often this is because of too much moisture...especially on the leaves

    Banana peels added down next to the roots of the roses so they can readily absorb the nutrients is a great boost to healthier plants & beautiful flowers!
