    Black spot (blackspot) is one of the most common diseases of rosebushes; and, if left unchecked, it can cause quite a bit of damage to yourrose garden. Caused by the fungusDiplocarpon rosae, black spot begins just as its name suggests, with black spots showing up on the surface of the leaves.

    Some roses are just more prone to black spot than others. Use baking soda - about 2 tablespoons -- dash of mild dish soap -- in a gallon of water. Spray once a week and immediately remove any fallen leaves from the ground and leaves that have spots from the rose itself. It is a never ending struggle and you need to be diligent about spraying, especially after a rain. Don't water your roses at night and use soaker hoses instead of top watering. Good luck.
