Hi All. I’ve got a couple of Juglans nigra which haven’t fruited well this year and look to have a bacterial infection on the case. It doesn’t seem to be infecting the nut as such. It looks like an anthracnose disease but I know little about this genus. The plants are in blue mountains in australia. They’re growing in the most divine basalt soil (kraznozem) and don’t appear to lack nourishment. thanks in advance
