Discula anthracnose is present all throughout the enviorment.... it won't
infect the soil in the sense that you mean, although picking up dead,
diseased leaves will help.

Hi,
I have a dogwood that is croaking inch by inch from anthroacnose and I
wonder if it is dangerous to leave it in the earth with the disease, or
will
it infect the soil. I want to put a stand of cluster birches in it's place
next year. Anyone know about this disease?
Thank you,
Jane
