Wandering around the garden today, I noticed that one of my two forsythia bushes is looking very unhappy. It has a large number of leaves that are brown around the edges. Many of the leaves are also turning yellow, especially along the veins. The problem resembles blight in potatoes or tomatoes (but forsythia isn't in the same family as these, so I wouldn't expect it to have the same diseases). I can see a similar browning of the leaves on a pot-grown wisteria in another part of the garden, which might or might not be related to the problem with the forsythia.
