What is black spot? Black spot is the most serious disease of roses. It is caused by a fungus, Diplocarpon rosae, which infects the leaves and greatly reduces plant vigour. Expect to see leaf markings from spring, which will persist as long as the leaves remain on the plant. The fungus is genetically very diverse and new strains arise rapidly.

Youâve already taken the first step in treating black leaf spot. Youâve been inspecting your garden on a regular basis and youâve caught it early.
