How to Identify Rose Blackspot.
Rose Blackspot starts at the base of the bush. The first signs are yellowing of the leaves and the appearance of the tell-tale black spots. They are large, a definite black and have a fringed edge.
As the disease progresses all of the leaves become infected, turn yellow and fall prematurely.
Rose blackspot can appear at any time and is encouraged by warm, wet weather and a close atmosphere.
