What are the black spots that are all over my rose bushes?
This is a disease called black spot. It is a common and disfiguring disease of roses. Fungicides are more effective when applied as a preventative disease control. We suggest alternating between different fungicides to reduce any chance of disease resistance. Roses will need to be sprayed once every 2-3 weeks from May through September to keep black spot and possibly other problems under control. See our staff for guidance and specific control recommendations.
