Blotches on Japanese Kerria Leaves

musicinthegarden(z6-7MD)July 10, 2010

A friend has a kerria bush that is suffering from something- see the picture- the newest leaves look fine but most of the established leaves have brown blotches throughout the leaves. Is this a sign of some nutrient deficiency in the soil or a disease? The hydrangea bush nearby seems to be doing fine.

The kerria has a Leaf and twig blight (caused by a fungus).
Stem cankers can develop if the blight spreads. You can treat it with a fungicide to try to control the spread or prune out the affected areas......This fungus will not spread to your hydrangeas.....but hydrangeas have their own leaf spot (cercospora)
