I have four pyracanthas that have developed some sort of blight. The blossoms and new berries are turning black and drying up and the leaves are also falling off. There is lots of new growth on other parts of the bush though. Two of these bushes are at least 30 years old and are usually a mass of berries that the robins feast on in the winter. I’ve attached some photos. Has anyone else had problems with their pyracanthas or does anyone know what this might be? Thanks
Possibly pyracantha scab, it's been a great year for fungal diseases. Pyracantha scab / RHS Gardening
