determining Tokudama heritage
I have anthracnose on my property to the degree that I can't spray enough to eradicate it. Apparently it's in the trees. According to the Ohio University thing on another thread, Tokudama is particularly susceptible to it. The only one of my hosta that really suffers with it is Blue Angel, (others have slight problems) which doesn't show up as having Tokudama heritage ('Aden 365' x 'Aden 361').
I would like to avoid anymore that are particularly susceptible to it. Does anyone have any ideas on how to do that?
