What is causing black spots on my Pieris leaves?

Our Advice:

Your Pieris has a fungal leaf spot disease. This can be controlled with Fungus Fighter from Bayer or Rose Shield from Doff. This will protect the new growth but the spots will remain on the older growth. Also, apply a foliar feed like Seaweed Extract with Sequestered Iron from Vitax, as leaf spot is always worse on underfed plants.
