Tricyrtis hirta question

I'm in Ohio right now and I have a question. There is
a Tricyrtis hirta here that is nice and large, just
starting to bloom and lovely. But, every year it gets
large brown necrotic spots all over the leaves. Is
this typical for this plant or is there a disease for
which I can spray? 
It is growing on the north side of the house, it gets
maybe 1 hour of direct sun at sunrise and then that is
it, it is very bright shade from then on. The soil is
mostly clay but I have been adding amendments over the
years to help improve it. There is a Japanese painted
fern right in front of it that gets more sun and it is
doing just fine (other than being crowded out). 
Thanks for all your help.
